Opis:
Oceny zmienności warunków cyrkulacyjnych na obszarze Polski względem jej centrum dokonano na podstawie charakteru cyrkulacji atmosferycznej, kierunku adwekcji i typologii cyrkulacyjnej opartej na dwóch wymienionych wskaźnikach cyrkulacji. Wyniki analizy poszczególnych wskaźników cyrkulacji atmosferycznej wykazały duży spadek zgodności wskaźników wraz z oddalaniem się od centrum Polski. Największą zgodność uzyskano w przypadku charakteru cyrkulacji atmosferycznej, a najmniejszą w przypadku typów cyrkulacji. W odległości 100 km od centralnego punktu wzorcowego stwierdzono zmianę typu cyrkulacji atmosferycznej w ok. 20-25% przypadków, a w odległości 300 km – w ok. 40%, a na południu Polski nawet więcej niż w połowie przypadków. Dynamikę zmian warunków cyrkulacyjnych na obszarze Polski sprawdzono opierając się na 16 typach cyrkulacji atmosferycznej określonych co 6 godzin i wyznaczonych metodą Jenkinsona i Collisona. Największe przestrzenne zróżnicowanie częstości zmian typu cyrkulacji atmosferycznej na inny odnotowano latem, a najmniejsze jesienią.
Evaluations of the variability of the atmospheric circulation in the area of Poland in relation to the center of country taken into account of the cyclonic and anticyclonic circulation, the direction of advection and circulation typology based on the above-mentioned two indices of atmospheric circulation. The results of the analysis of particular atmospheric circulation indices showed a significant decrease in the compatibility indices with distance from the center of Poland. The highest compatibility was obtained in the case of the cyclonic and anticyclonic circulation, and the lowest in the case of atmospheric circulation types. At a distance of 100 km from a center of reference point the type of atmospheric circulation changes in approx. 20-25% of cases, and at a distance of 300 km - in approx. 40%, and in the southern part of country even more than half of the cases. The dynamics of changes in the circulation conditions in the area of Poland were checked on the basis of 16 atmospheric circulation types determined every six hours based on the Jenkinson’s and Collison’s method. The highest spatial diversification of frequency of transition the specified atmospheric circulation type to another occurred in summer and lowest in autumn.

Opis:
The study presents variability of different circulation indices above the Spitsbergen for the period 1951-2000. Investigated area covers the part of the Atlantic sector of the Arctic located between 75-80°N and 0-30°E. The study based on the original calendar of circulation types (Niedźwiedź 1981, 2001), prepared with the help of the synoptic maps of Europe (Europäischer Wetterbericht, 1976-2000, Tägliche Wetterbericht 1950-1975). Twenty circulation types have been distinguished. The advection directions are marked by the capital letters while the anticyclonic situations by the subscript a and the cyclonic ones by subscript c; for example, Wa and Wc denote the anticyclonic and cyclonic situations respectively, with the air advection from the West. Thus, there are 16 circulation types with definite directions of the air masses. The other 5 situations are nonadvective: Ca - centre of anticyclone, Ka - anticyclonic wedge, Cc - centre of cyclone, Bc - cyclonic trough, and x - col and the situations which cannot be classified. This classification is similar to Lamb (1972) types and based on methods described in the most important works in synoptic climatology (Barry an Perry 1974, Yarnal 1993). The frequencies of the occurrence of all the distinguished circulation types for the 50-years period of 1951-2000 are presented on the table 4. On the average, the anticyclonic wedge (Ka ? 10.4 %) is the most frequent in the Spitsbergen. The second one is situation Ec and NE occurs during 9.9 and 8.8% of the days. The centre of high pressure over Spitsbergen (1.3 % of the days) and the NW situation (1.5 % of the days) are the least frequent. Weather and climate of Spitsbergen are modelled by the intensive cyclonic activity during 56 % of the days in a year. The largest frequency of the occurrence of low pressure systems is characteristic for the period from September to March with maximum in November (66 %), December and January (65%). The number of days with high pressure systems exceeds 50 % only in May (59 %). The variability of circulation have been obtained using the simple circulation indices: zonal westerly circulation W index, similar to P progression index, index of southerly circulation - S, and index of cyclonicity - C, as proposed by R. Murray and R. Lewis (1966) with some modifications. The author of this paper calculated these indices for each year, season and month (tables 1-3). The most characteristic for Spitsbergen is the zonal form of circulation with the eastern component (W = -147 for a year) with the great intensity in the period from October to April (March ?20.9). The minimum in the eastern air-flow can be observed in summer (July +0.7). Another characteristic feature for Spitsbergen is predomination of the cyclonic patterns (index C = 56 for a year), especially in the period from September to March (November 12.8). In May the index C is negative (-9.4), which confirms the great activity of anticyclonic pattern. Among the southerly circulation forms the northern component dominates (index S = -36 for a year). Only in July and August the opposite situation can be observed. Circulation forms over Spitsbergen have been fluctuated in the long-term period. In 1951-2000 the greatest changes have been observed in the indices C and W (fig. 3-7). Significant increasing trend was observed in annual values of C and S indices. Southerly circulation index S is well connected with North Atlantic Oscillation (NAO) index (table 6). The best correlation between the mean temperature at Hornsund and circulation indices exists for the S index (table 7).

Opis:
Evaluating synoptic conditions and the incidence of fog cases as well as number of days with fog across a large spatial spectrum such as atmospheric circulation and comparing results to local scale analyzes will help to accurately identify conditions conductive to formation of fogs on the territory of Poland. The aim of the study is to analyze the time of fog formation during the day, fog duration, and the extent of limitation of the horizontal visibility. Data coded in METAR (Meteorological Aerodrome Report) messages was used to perform the analysis of synoptic from 8 stations located at the largest airports in Poland. In the analysis, the main criterion was the number of cases when horizontal visibility limited below 1 km – number of fogs. Results show that there is a clear, seasonal pattern of fog frequency for all stations in this study. For a majority of stations, the minimum number of fogs occurred during the summer months and the maximum number of fogs was observed in October and November. The probability of fogs in the cold half of the year, during the anticyclonic circulation, is slightly higher than during cyclonic circulation and is connected with meridional air advection. In the warm half of the year the probability of fogs during cyclonic circulation increases. Fog duration in most cases did not exceed 3 hours for all stations. At the stations analyzed, fog most often limits the horizontal visibility to 500 m, but there are seasonal differences in the frequency for separated ranges of horizontal visibility.

Opis:
Maximum daily precipitation and the number of days with precipitation 10.0 mm was analysed in Polish Polar Station in Hornsund (Spitsbergen), based on the measurements during 8008 days in the period 1978 June - 2000 July. The geographical coordinates of the station are following: j = 77°00? N, l = 15°33? E, Hs = 11 m a.s.l. This region is characterised by relatively large annual precipitation, varied from 230 mm in 1987 up to 640 mm in 1996. The largest diurnal total of precipitation - 58.3 mm was observed on August 1, 1994. The second high value 52.6 mm was noticed on September 6, 1996. During the observed period only 5 times daily precipitation exceeded 40 mm and 14 time was higher than 30 mm. Return period for possible daily precipitation greater than 70 mm is less than once in a hundred years. In the annual course the maximum of precipitation was observed mainly in August and September. Also the largest precipitation appears most often during the advection of air from the South and South-West with cyclones coming from the Atlantic Ocean. Special attention was made to the daily precipitation >=10 mm. they occurred during the 201 days (2.5%) and bringing about 35% of annual total. The probability of such events is highest in autumn (25%) during the south westerly cyclonic circulation type (SWc). Two other circulation types are caused also such precipitation: southern cyclonic type (Sc) with probability 24% and south westerly anticyclonic ones (SWa), with probability 11.5%. During the last decade of 20th century there was observed the increasing tendency in frequency of large precipitation in Hornsund. The sudden increase take place since 1994. These changes were connected with greater frequency in the intensity of westerly and southerly atmospheric circulation expressed by the zonal and meridional circulation indices.

W artykule przedstawiono zmienność przestrzenną przebiegu rocznego ciśnienia atmosferycznego na Antarktydzie. Stwierdzono dwa typy przebiegów rocznych ciśnienia. Na wybrzeżu występuje przebieg charaktery-zujący się półroczną oscylacją, z maksymalnymi wartościami w sezonie letnim i zimowym oraz najniższymi w przejścio-wych porach roku. We wnętrzu kontynentu najwyższe ciśnienie występuje latem, a najniższe w chłodnej połowie roku. Największe amplitudy roczne ciśnienia występują we wnętrzu kontynentu. W ostatnich dwóch dekadach XX wieku zaznaczyły się istotne zmiany w przebiegu rocznym ciśnienia atmosferycznego.
At the polar latitudes of the Southern Hemisphere a circulation cell functions which is connected with the strong baric wedge feature of the atmosphere occurring between the Antarctic anticyclone and a very deep circumpolar trough by the Antarctic coastline. The circulation system in the Antarctic region shows seasonal variability called Southern Annular Mode (SAM). In the cold season the tropospheric exchange of air masses strengthens due to the increase of the katabatic winds? speed. The relocation of air masses from over Antarctica to its peripheries has an influence on the annual course of the atmospheric pressure. In the elaboration mean monthly air pressure values were taken into account from 106 Antarctic stations from the beginning of measurements to 2000. On the basis of these data the mean annual course of the atmospheric pressure has been counted as well as the yearly pressure range. Annual courses from two periods: 1958-1980 and 1981-2000 were also compared. Over the Antarctic the annual course of the atmospheric pressure is complex. At the costal part of the continent there are two maxima (in summer and in winter) and two minima in the transient seasons. This course is called semi-annual oscillation (SAO) in the literature. However this phenomenon shows certain regional specifics. On the Antarctic Peninsula and South Orkney Islands the winter maximum is more distinct, while minima are shifted to February and November. In the inland the winter maximum decreases with the distance from the coast and at stations situated in the highest parts of the glacial plateau the highest pressure values occur in summer and distinctly lower ones in winter. At some inland stations a slight increase of the pressure can be observed in the middle of winter what refers to the thermal coreless winters occurring frequently in this region. The annual range of the atmospheric pressure decreases from the coast (15-7 hPa) to the interior of the continent, where it reaches values above 20 hPa. During the last two decades of the 20th century significant changes took place in the annual courses of the pressure in comparison to the years 1958-1980. On the South Orkney Islands and the Antarctic Peninsula the pressure increased in summer and in autumn, while in winter distinctly decreased. At the remaining part of the Antarctic coast pressure decrease occurred in every seasons, and in the Weddell Sea region the autumn and spring minimum significantly deepened. At the majority of the stations the annual amplitudes of the atmospheric pressure decreased after 1980. These changes contributed to the disturbances in the functioning of the Antarctic climate system. On the Antarctic Peninsula the air temperature increased, while at many stations in the Eastern Antarctic considerable cooling occurred.

Opis:
The primary objective of the study was the determination of the spatial and multiannual variability of occurrence of days with very strong and extreme cold stress in Poland according to the Universal Thermal Climate Index (UTCI), as well as determination of baric conditions favouring their occurrence. The study was based on data from the years 1966/67 to 2018/19 from the Institute of Meteorology and Water Management – National Research Institute and National Centre for Environmental Prediction/National Centre for Atmospheric Research (NCEP/NCAR). The research showed a statistically significant decrease in the number of days with very strong and extreme cold stress on half of the analysed stations, and a slight tendency or no changes on the remaining stations. The occurrence of days with extreme cold stress in Poland, as revealed by the analysis was primarily related to the presence of high-pressure systems blocking zonal circulation. The study resulted in the designation of three circulation types, i.e. two types related to anticyclonic systems and one cyclonic type.

Analysis of time series was performed of cloudiness, air temperature and precipitation for the years 1951-2000, the data used representing lowland Poland. The properties of the temporal course of these elements of climate and the interrelations between their variability in time have been determined. The strength of dependence of precipitation and temperature upon the magnitude of cloudiness in the annual cycle has been assessed with the linear correlation coefficient. The essential climate-forming role of cloudiness has been confirmed. The magnitude of cloudiness over Poland explains up to 70% of variability of temperature and precipitation. These interrelations are the strongest in the warmer half of the year. Atmospheric circulation and cloudiness explain up to 85% of variability of the climate elements studied.

Opis:
This article deals with an attempt to estimate the value of the net balance of Hansbreen (SW Spitsbergen).In order to estimate thes value an assumption has been made that the value of the net balance of Hansbreen is a function of two groups of factors, i.e. static and dynamic ones. The static elements (georgaphical location of Hansbreen, topography of the glacier and its surroundings, etc.) have no influence on the elements of the interannual changeability of the balance; a constant value will represent these elements in formulae. A group of dynamic factors that introduces an interannual changeability to the net balance is made up of a set of meteorological factors (mainly the course of air temperature, precipitation and cloudiness). The said meteorological factors are influenced by the character of atmospheric circulation. Because the main features of the character of the interannual changeability of the air circulation over that area are influenced by the spatial distribution of the anomalies sea surface temperature (SST), the analysis of variances has been chosen as the method used to define the direct statistical estimation of winter and summer balances as the function of monthly anomalies in SST occurring in the North Atlantic in a preceding period. As a result of statistical analysis, two linear functions of great statistical significance have been obtained, i.e. formula [1] and [2] enabling the estimation of winter and summer balances respectively. These functions use the values of anomalies in SST as independent variables. The influence of these values on the course of changeability in atmospheric circulation over the Nordic seas is obvious. The calculated values of the net balance of Hansbreen, estimated by means of the above mentioned functions and the values observed (Fig. 4) proved to be almost the same. Having the values of anomalies in SST (Reynolds data set) a sequence of values of net balance of Hansbreen has been estimated for the period 1970/71÷1996/97 (Table 2, Fig. 5) with the help of this method. An error of values calculated in this way can be found within limits ą0.106 m. water equivalent. The values of the calculated net balance taken from the above mentioned period were used to find by means of best estimating correlation between Hansbreen net balance and temperature and precipitation sums at Isfjord Radio station. Thanks to these results, the next sequence of values of Hansbreen balance for period 1926/27÷1969/70 (Table 3, Fig. 6) has been calculated. The final values are of no statistical significance and contain unknown errors. If they are close to reality it might mean that the balance of Hansbreen has been permanently negative since the end of the 20-ties.

The synoptic situations types were defined using the classification proposed by Niedźwiedź (1981), whereas the sunshine duration values came from research carried out as part of the Integrated Monitoring of Natural Environment Project. The study covered the frequency of occurrence of individual circulation types and their influence on the sunshine duration in an annual and a long-term course.
W opracowaniu przedstawiono zagadnienie związku usłonecznienia z cyrkulacją atmosfery na podstawie badań przeprowadzonych w Koniczyncek/Torunia w latach 1999-2013. Usłonecznienie było mierzone heliografem Campbella-Stokesa, natomiast sytuacje synoptyczne zostały określone wg klasyfikacji T. Niedźwiedzia. W badanym okresie w Koniczynce stwierdzono istotną statystycznie korelację usłonecznienia z częstością typów sytuacji synoptycznych. Największe usłonecznienie wystąpiło w roku o największym udziale antycyklonalnych typów sytuacji synoptycznych. Wykazano, że pogodzie bezsłonecznej zdecydowanie sprzyjają układy cyklonalne, natomiast największym dziennym sumom usłonecznienia typy antycyklonalne.

Opis:
The study presents variability of simple circulation indices above Spitsbergen for the period 1899-2004 in January, based on original calendar of synoptic divided from the synoptic maps. After calculation of synoptic types frequencies the further results have been obtained using the simple circulation indices: W - westerly, zonal index, S - southerly - meridional index, C - cyclonicity index, as proposed by R. Murray and R. Lewis (1966) with some modifications, as well as Spitsbergen Oscillation (OS) defined as the standarized pressure difference between Bjornoya and Longyearbyen. The negative value of W index is typical for Spitsbergen, according to great frequency of eastern airflow. Variability of January temperature in Svalbard (t01SV) were investigated on the basis of averages from four stations: Isfjord Radio and Svalbard Lufthavn, as well as from Polish Polar Station in Hornsund Fiord on SW part of Spitsbergen, and from Bjornoya (Bear Island) - about 300 km SSE from Hornsund. After reconstructions of some lack data on the basis of linear regression, temperature data were obtained for the period of 1912-2004. For the temperature the main feature is period of cooling in the years 1912-1918 and then the great warming during the decade of 1930th (1933-1937). During the years 1937-1971 was observed the significant decreasing trend in January temperature to the cool period of years 1962-1971. The last period 1971-2004 has no any trend in temperature. But three large fluctuations took place with warm Januarys of 1972-1974, 1990-1992 and 1999-2001 and cool ones of 1975-1982, 1993-1998 and 2002-2004. Temperature of January changes in Spitsbergen depend on a great extend of circulation factors, mainly from the southern (S) and zonal circulation indices (W) or Spitsbergen Oscillation index (SO). Using the models of multiple regression was possible the recontruction of January temperature since 1899 on the basis of circulation indices. They explained about 63% of variance in temperature.

Opis:
There are many classifications of atmospheric circulation types. In Poland, the most important one, used by Polish weather services, is the classification of circulation types developed by Lityński. This paper proposes four modifications to the currently used algorithm for determining atmospheric circulation types. The proposed algorithms have been compared and it has been shown which one produces a catalogue of circulation types in which the division of the distribution of the values of the three indices (the zonal index Ws, meridional index Wp and cyclonicity index Cp) into three classes is the closest to being equally likely. In 19862015, the classification scheme that deemed to be the best, difered in above 19% of cases from the currently used classification.

This case describes structure of solar radiation balance in Ny-?lesund, Spitsbergen, basing on twenty-four-hour?s magnitudes in 1989-2003. We put to the analysis each radiation streams: shortwave and longwave. Basing on it one year?s and monthly balances were estimated: (K*, L*, Q*). The radiation data used in this article are derieved from: Norsk Polarinsitutt in Oslo: Hisdal, Finnekasa and Vinje (1992) and Hisdal and Finnekasa (1996); 'The Alfred Wegener Institute for Polar and Marine Research': Koenig-Langlo and Marx (1997). The data of clouds from Ny-Alesund are derieved from: Climatolology Division, Norwegian Meteorological Institute, Norway. In 1989-2003 period - annual radiation balance Q* in whole spectrum was oscillating from - 71 MJ/m2 to 194 MJ/m2, average Q* was 57 MJ/m2. Highest values of Q* in year are recorded on June, July - average - 210-260 MJ/m2, lowest on polar night period -October-February (-87 MJ/m2 to -100 MJ/m2). Short-wave radiation balance K* was depending on sun level, sculpture of the earth?s surface and cloudiness modify amount of downward sun energy. Yearly balance sums of short-wave radiation K* was oscillating from 931 MJ/m2 to 1438 MJ/m2, average -1178 MJ/m2. Yearly course of stream K and balance K* shows maximum from April to August and zero values in November-February period. Analyzing many year?s estimation -highest yearly sum of K stream - 2634 MJ/m2 - was recorded on 1993 and lowest - 2157 MJ/m2 on 1990, average of sums in this period was - 2402 MJ/m2. Average yearly balance of L* was 1120 MJ/m2 on 1989-2003 period. Annual balance sums were oscillating from -936 MJ/m2 to -1265 MJ/m2.

Opis:
The aim of the study washas been to determine the differences in the 24-hour means values of some selected meteorological elements between the stations analysed and also to determine the influence of atmospheric circulation on their distribution. Meteorological data collected at the Polar Station of the Institute of Geophysics of the Polish Academy of Sciences in Hornsund and the Calypsobyen Station of the Maria Curie-Skłodowska University of Lublin wasere used for the present research. The present studies showed that air temperature in Calypsobyen is on average 0.6°C higher than in Hornsund. Calypsobyen is warmer than Hornsund fromat almost all circulation directions. Hornsund is warmer only in the case of the NW direction. The highest levels of temperature differences (> 1°C) occur from theat S and SW directions. Calypsobyen was 0.3°C colder than Hornsund only in the case of the NWc type. Regarding the average total cloud coveriness of the sky [0-10], the difference between the two stations analysed was as small as 0.1. This results from thea high total cloud coveriness of the sky during summer. No differences were found in the case of medium wind velocity levels similarly as was in the case for the of cloud coveriness. The a mean difference forro this parameter was 0.1 m/s. The location of the station, as well as the orographic reletions in its surroundings, exerts a significant influence on the difference in thetiation of wind velocities in relation to the directions of the circulation directions. The total - taken ever twenty-four hour sums - of the atmospheric precipitation levels as an averaged with to the circulation directions in Hornsund were on average 0.8 mm higher than for in Calypsobyen. Precipitation levels were higher in Calypsobyen only from theat N and E directions and in the situation of a weather wedge over Spitsbergen (Ka), however, even then the values of these differences were small (0.1-0.2 mm). Analysis of the data analysis pointed to the significance of the direction of the circulation direction and its influence on the value of differences between the meteorological elements selected. In some cases (i.e. wind velocity, precipitation level) local factors - and including orographic relations and the location of the measuring site - are decisive.

Opis:
The meteorological measurements were carried out on NW Spitsbergen on the Waldemar Glacier (surface 2.66 km2) in three points: ATA (133 m a.s.l., marginal zone), LW1 (130 m a.s.l., snout of glacier), LW2 (380 m a.s.l., firn part). The base station of Toruń Polar Expedition is situated on the north part of Kaffioyra (KH, 11 m a.s.l.), about 3 km away from glacier. The air temperature and relative air humidity were measured by termohigrographs in standard meteorological boxes, and precipitation by Hellmanns pluwiometer in the period 14.07-8.09.1999. The weather conditions on the Kaffiöyra region are determined by solar and circulation factors. In the summer season 1999 north and east advection of air masses dominated. The meteorological conditions on Waldemar Glacier are formed by the influence of two contrasting environments: the glacier and its moraine foreground. The mean air temperature in summer 1999 at the Kaffiöyra equaled 5.4°C and at the moraine of the Waldemar Glacier (ATA) 5.2°C. On the glacier the air temperature was much lower, and on the snout (LW1) was 4.5°C and decreases with the altitude (LW2 3.2°C) . The average gradient of air temperature between LW1 and LW2 stands was 0.53°C/100 m. Between the warmed up dark moraine ground (ATA) and the melted surface of the glacier a ?thermal jump? occurred (0.4°C on the distance 160 m). The highest maximum of air temperature at KH was 18.1°C, and on the Waldemar Glacier 16.4°C (LW1) and 16.5°C (LW2). The relative air humidity on Spitsbergen are formed under the influence of oceanic water and foehn phenomena. In summer season 1999 the mean relative air humidity was 84% at the Kaffioyra and increased with the altitude on the Waldemar Glacier (LW1 ? 86%, LW2 ?89%). In the period 21-07-31.08 at the Kaffioyra sums of the precipitation equaled 58.4 mm and on the glacier: 85.2 mm (133 m a.s.l.), 100,6 mm (233 m a.s.l.), 108.9 mm (380 m a.s.l.) and 131.8 mm (421 m a.s.l.). In summer season the meteorological conditions on the Waldemar Glacier show a large variability. It is a result of incoming air masses, warm from moraine foreground up the glacier and cool from the glacier plateau, from the interior of Spitsbergen.

Opis:
Dni mroźne, definiowane jako dni z Tmax<0°C są jednym z termicznych wskaźników współ-czesnych zmian klimatu. Celem artykułu jest określenie wieloletnich zmian częstości występowania dni mroźnych w Hornsundzie oraz określenie relacji pomiędzy ich występowaniem i cyrkulacją atmosfery. Badania przeprowa-dzono na podstawie dostępnych danych dobowej maksymalnej temperatury powietrza (26.07.1957-16.08.1958 MRG; 4.07.1978-29.02.2012). Średnio w Hornsundzie notuje się 183 dni mroźnych w roku. Najczęściej pojawiają się one w marcu, zaś w ogóle nie występują w lipcu i sierpniu. W badanym okresie częstość występowania dni mroźnych istotnie malała w maju, czerwcu i grudniu. Tendencja spadkowa dotyczy również rocznych wartości liczby dni mroźnych. Sezonowe zróżnicowanie relacji pomiędzy częstością występowania dni mroźnych a cyrkulacją atmosfery jest słabsze niż w przypadku dni z przejściem temperatury przez próg 0°C. W większości miesięcy największym prawdopodo-bieństwem ich wystąpienia charakteryzują się typy antycyklonalne: Na, NEa, Ea, NWa oraz Ca i Ka. Występowaniu dni mroźnych nie sprzyja adwekcja ciepłego powietrza z południa.
Ice days defined as days with daily maximum temperature below 0°C are placed amongst the indices of current climate change. This paper aims at research both the long-term variability in the ice days occurrence and their relations to atmospheric circulation. All available data on daily maximum temperature were used (26.07.1957-16.08.1958 MRG; 4.07.1978-29.02.2012). On average, 183 ice days a year are noted in Hornsund. The highest number of the days occurs on March whereas they do not appear on July and August. The frequency of ice days were significantly lowering in May, June and August. The downward trend was also found in the annual index values. Seasonal differentiation of the relations between the ice days occurrence and atmospheric circulation are weaker than in case of days with freeze-thaw events. In majority months the highest probability of the ice days occurrence is linked to the six anticyclonic types (Na, NEa, Ea, NWa, Ca and Ka). Advection of warm air from south results in rarer ice days.
