Opis:
The article presents the changes in the values of average air temperature and its spatial diversity in the four seasons of the year (spring, summer, autumn, winter) in the years 1981–2010 compared with the 1971–2000 period. In the 1981–2010 period (the new climate normal currently in force) the largest increase in air temperature expressed in the average area value occurred in summer and reached 0.5°C. In spring and autumn the increase in average air temperature was smaller and was 0.4°C and 0.3°C respectively; in winter average temperature did not change compared with the previous climate normal.

Opis:
The forest line has been widely studied by a number of scientists representing various research disciplines. Changes in its position are an indicator of climate change. However, despite numerous studies, it is not always known what has the greatest influence on the position of the forest line. In the Tatras, which are Alpine moun-tains, the position of the forest line in places not disturbed by human activity or slope processes mainly depends on the annual mean air temperature and the number of days with negative temperature and its value in the warm season. The most unfavourable thermal conditions are found at the bottoms of concave landforms, just above the forest line. This thermal barrier effectively limits the upward movement of the forest line, even if the average annual temperature increases. Small concave landforms may have a higher vertical temperature gradient and lower air temperature values at their bottoms than larger and higher-lying forms.

Opis:
The climate of a high-altitude postglacial cirque, such as Kozia Dolinka, is conducive to the occurrence of permafrost. Both the depth of permafrost and the area it covers, as well as the presence of year-round snow patches, can serve as indicators for assessing the impact of global warming on the climate of mountains, including the Tatras. With few meteorological stations to survey the remote and inaccessible high-altitude areas of the Tatra Mountains, any research must rely on measurements spanning limited time periods. Against this background, the 5-year series of temperature measurements from the Kozia Dolinka cirque obtained by the Institute of Geography and Spatial Organization of the Polish Academy of Sciences (IGiPZ PAN) can be used to analyze air temperature patterns on concave and convex terrain forms in the alpine climate zone if compared to the results of measurements from stations of the State Hydrological and Meteorological Service located nearby, i.e. the Kasprowy Wierch HighMountain Meteorological Observatory and the Hala Gąsienicowa Nival Research Station of the Institute of Meteorology and Water Management, National Research Institute (IMGW-PIB). This study confirms that there is a relationship between air temperature and the formation and duration of snow cover on concave and convex terrain forms. It also reveals a hitherto unknown fact that concave terrain forms, i.e. postglacial cirques, of the alpine zone have milder thermal conditions in winter than convex terrain forms. The analyses highlight the need for further, more detailed research using modern automated meteorological stations.

Opis:
Results of air temperature measurements in the 1957-2014 multi-annual period were analysed in the paper. The data originated from Jelcz-Laskowice locality situated in the south-western part of Poland, at the flat part of the Lower Silesia, on Silesian Lowlands. Average annual and monthly air temperatures and the number of days of thermal seasons duration were analysed. Trends of changes were set and extreme values of average monthly air temperatures were analysed. Mean annual air temperatures in the studied multi-annual period revealed a tendency to increase. Average monthly extreme values of the analysed factor revealed a similar direction of changes; however, more apparent changes occurred for the maximum values. Over the analysed period, average monthly air temperatures revealed a tendency to increase. The most serious changes occurred in July, slightly lesser in August, May and April. The number of days in the years 1957-2014 in the interval limited by the air temperature threshold values: 0°C, 5°C and 15°C was greatly diversified. Analysed results had a clear growing tendency for the summer, slightly lower for the spring, but evidently declining for the autumn.

Opis:
Krakow is one of the most polluted cities in Poland. Its natural ventilation is limited due to the location of the city in a river valley. Air temperature inversions are an important element of the local climate in Krakow and a factor strongly influencing air pollution dispersion conditions. Traditional, multi-annual (1972-1996) measurements of air temperature, from three rural stations, and 1-year (03.2009-02.2010) intensive automatic measurements from two rural stations, one urban station and from a mast top 115 m above the ground were used. In the night time, inversions are less frequent in the urban than in the rural area, but still the frequency is over 30% from spring till autumn. In the studied 100-meter air stratum, no crossover effect was found. The relatively high frequency of air temperature inversions in the urban area of Krakow is a significant mesoclimatic difference in comparison with cities located in flat areas. It is also a factor seriously decreasing the natural ventilation and air pollution dispersion conditions.

Opis:
Diurnal air temperature ranges (DTR) have been counted based on the monthly mean values of the daily maximal and minimal air temperature from 23 Antarctic stations. DTR shows a considerable spatial differentiation on the Antarctic. The lowest DTR values (4-6°C) occur along the western coast of the Antarctic Peninsula and on the subantarctic islands. At the remaining coast of Antarctica the mean DTR vary from 6-7°C to 10°C at the stations situated on higher geographical latitude. In the Antarctic inlands the largest DTR values occur at the highest parts of glacier plateau (8-9°C), while on the South Pole they are distinctly smaller (6°C). In the annual course of DTR the following types have been distinguished: oceanic type at the western coast of the Antarctic Peninsula with small DTR in summer (2-4°C) and twice higher in winter; oceanic-continental type at the coast of Eastern Antarctic with large DTR during the whole year; continental-oceanic type with high DTR in summer and still higher (up to 13°C) in winter occurring at Western Antarctic and in the Weddell Sea basin; continental type characteristic for the interior of the continent with the highest DTR in summer (11-12°C) and smaller in winter; polar type with small DTR in summer (to 3°C) and considerable higher in winter (7-8°C). A decrease of DTR occurred on the Antarctic in regions characterized by increasing temperature in the second half of the 20th century, especially on the western coast of the Antarctic Peninsula, on the coast of Ross Sea and on the Queen Maud Land. The decrease in the DTR values was connected with the quicker increase of daily minimal air temperatures. On the other hand, in the regions where cooling was noted the DTR values increase (inlands of Eastern Antarctic and South Pole, and the Weddell Sea basin), mainly due to the fall in daily minimal air temperatures.

Opis:
In order to cover the subject matter, monthly data concerning air temperature from over the years 1951-2005 were gathered from 34 meteorological IMGW stations situated in Poland. Statistical characteristics included mean values, extreme ones, amplitudes, standard deviations, in different time intervals: months, seasons, and year. Multi-year variability of temperature was described using linear trend and the increase or decrease in the air temperature was evaluated by means of direction coefficients of simple linear regression referring to the period of 1951-2005. In Poland in the studied multiannual period the largest increase in the temperature of air occurs in February - from about 0.4°C per 10 years in the south of the country to about 0.7°C in the north. Other months of a large (statistically significant) increase in temperature are March, May and August, the mean air temperature increases from about 0.3 to 0.6°C per 10 years. The studied trends of temperature in the 10 year periods show a decrease in the temperature till the end of the decade of the 70s, and then its distinct increase in the last two decades. This is also confirmed by accumulated deviations of the annual average from the multiannual value which is found to be clearly increasing since 1987. The decrease in the annual amplitude of the air temperature in decades of the period over 1951-2000 (particularly distinguished in the stations situated by the sea indicates a stronger and stronger effect of the Atlantic Ocean on the climate in Poland).

Two coniferous forest communities were selected for analysis: a marshy coniferous forest and a young spruce forest, both located in the Borecka Forest. Thermal conditions develop differently in each community during the spring, due to different tree crown closure, which influences the amount of direct solar radiation reaching the substratum. Soil humidity is another factor influencing the air temperature, since the capacity and thermal inertia of the soil depend on its humidity. The results of the study are compared with thermal conditions outside the forest.

Opis:
On the Antarctic the annual course of air temperature shows a considerable spatial differentiation. Over the inland the course of temperature during the year is conditioned by insolation-radiational factors. On the coast the role of circulation factors connected with the advection of air masses from above the ocean or from the interior of the continent. In the paper mean monthly air temperatures from 56 stations making standard meteorological observations and from 38 automatic weather stations (AWS) have been used. On the Antarctic there types of annual air temperature courses can be distinguished: Oceanic - characterised by positive air temperatures in the summer season with the highest temperatures in February and by mild temperatures in the winter months (to -10°C). As a result of the ocean influence spring is considerable colder then autumn. The annual amplitudes are small (to 10-15°C). This type occurs on the western coast of the Antarctic Peninsula and on the subantarctic islands. Continental - with very low air temperatures. The warmest month is December with temperatures below -30°C in the interior of the continent. In winter the lowest mean monthly temperatures reach -70°C. The temperature frequently increases in the middle of winter; this phenomenon is called kernlose winter. The annual amplitude of air temperature is not high and in the interior its value reaches 30-35°C. The continental type includes the whole Antarctic except the narrow coastal belt. Coastal - characterised by air temperature around 0°C in the summer period. The warmest month is January. The lowest temperatures occur in January (-30° do -40°C). The growth of temperature in spring delays the heat uptake for the melting of sea ice. The annual amplitude of the air temperature is quite high and exceeds 20°C. Due to the influence of circulation factors on the Antarctic the annual course of the air temperature shows a large variability from year to year.

Opis:
The dissertation takes up the problem of homogeneity of the air temperature field in Poland in terms of cyclical fluctuations. The thermal conditions within the area of Poland were described through the chronological series of the monthly a verages of air temperature, registered at 58 stations of the Institute of Meteorology and Water Economy in the years 1951-1990. The spatial differentiation was determined of the periods, amplitudes, and phases of the identified short-term fluctuations of air temperature, and the synchronicity of these fluctuations on the area of Poland was demonstrated. An objective of the study was constituted, as well, by the identification of the natural causes of the periodicity of air temperature changes - demonstration of the synchronicity (correlation) of the cycles of air temperature, atmospheric circulation, and solar activity. An attempt was also undertaken of determining the share of the short-term variability in the observed trends of air temperature in Poland. The significant cyclical components identified on the basis of the data from the years 1951-1990 were made use of in the forecast of air temperature in Poland for the decades to come.

Opis:
The paper presents the calculation of the vertical air temperature gradients for the free atmosphere within the mountainous area of the southern part of Poland (separately for the Carpathians and the Sudety Mts.) and the northern slope of the Karkonosze Mts., the highest part of the Sudety Mts. The gradients were determined on the basis of the analysis of the aerological diagrams with the least squares technique and the method of differential quotient between the air temperature values noted at the neighbouring weather stations. The average annual gradient of air temperature - irrespective of the method applied and the spatial scale - was equal 0.5°C/100 m of altitude. The gradients calculated feature the typical - for the moderate latitudes - annual course, with the lowest values in the cooler part of the year (0.4°C/100m), and the highest - in the months of the warmer half-year (0.6°C/100m). This is the result of the annual changes in the radiation balance: in the winter months the longwave out-radiation from the active surface dominates, leading to the decrease of the gradient values, white in the summer months the heating of the earth's surface dominates, entailing the increase of the air temperature differences in the vertical profile of the boundary layer of the atmosphere. Each of the methods of calculation of the vertical gradients of air temperatures gives the correct image of the directions and range of temperature changes corresponding to the increase of the altitude above the sea level. These methods, though, serve different purposes, since they define the properties of the thermal conditions existing in the free atmosphere (aerological gradients) and in the so-called mountain atmosphere. In the second case the geographical gradients define the features of the macroclimate, while the hypsometric ones - of the climate associated with the influence of the mesoforms of the surface relief. A comparison of the geographical or hypsometric gradients with the aerological ones gives the opportunity of developing the description of the influence exerted by the earth's surface on air temperature field observed in the free atmosphere.

Opis:
Soil temperature is an important factor in biogeochemical processes. On-site monitoring of soil temperature is limited in spatio-temporal scale as compared to air temperature data inventories due to various management difficulties. Therefore, empirical models were developed by taking 30-year long-term (1985-2014) air and soil temperature data for prediction of soil temperatures at three depths (5, 15, 30 cm) in morning (0636 Indian standard time) and afternoon (1336 Indian standard time) for alluvial soils in lower Indo-Gangetic plain. At 5 cm depth, power and exponential regression models were best fitted for daily data in morning and afternoon, respectively, but it was reverse at 15 cm. However, at 30 cm, exponential models were best fitted for both the times. Regression analysis revealed that in morning for all three depths and in afternoon for 30 cm depth, soil temperatures (daily, weekly, and monthly) could be predicted more efficiently with the help of corresponding mean air temperature than that of maximum and minimum. However, in afternoon, prediction of soil temperature at 5 and 15 cm depths were more precised for all the time intervals when maximum air temperature was used, except for weekly soil temperature at 15 cm, where the use of mean air temperature gave better prediction.

Opis:
Seasonal variability is the complex non-linear response of the physical climate system. There are two types of natural variability: those external and internal to the climate system. In any given season, natural variability may cause the climate to be different than its long-term average. This study examines with the seasonal variation of the maximum temperatures during the summer season. In addition, the maximum temperatures in May become close to the characteristics of the summer season. The monthly data for maximum temperature of May, June and July were used from Iraqi Meteorological Organization and Seismology (IMOS) for 47 years from 1970 to 2017 for Baghdad city. This period was long enough to estimate the range of approaching maximum temperature (Tmax) May to summer. Results revealed a significant Tmax for Baghdad during the second period (1992–2017) and ?shown similar behavior of Tmax in May to June and July; on the contrary that first period (1970–1991). In second period, two phases have been found out, positive phase and negative phase. The positive phase were happened in 1995, 1999, and 2006, and the negative phase was four cases (1992, 2004, 2013, and 2016), while a few cases recorded in first period. The amplitudes of monthly variability had same distance of leaner correlation especially in 1999 and 2013 that represent coherent wave with summer seasons. The variance difference for Tmax between May and June approximately was 2°C for second study’s period, while exceed this range in first period. This variance change to 7.5°C when found difference between July and May.

Opis:
Celem pracy było zaprezentowanie przebiegów średnich miesięcznych i rocznych wartości temperatury powietrza w rejonie Bydgoszczy ze szczególnym uwzględnieniem kształtowania się ich tendencji w latach 1949–2008. Ze względu na powszechnie poruszany i żywo dyskutowany, zwłaszcza w ostatnich latach, problem ocieplenia klimatu Polski, dokonano także porównania charakterystyk temperatury powietrza w całym 60-letnim okresie badawczym (1949–2008) i ostatnim 15–leciu (1994–2008). W celu wyeliminowania wpływu lokalnych, miejskich czynników antropogenicznych, w pracy wykorzystano pomiary temperatury powietrza prowadzone w niewielkiej miejscowości Mochełek pod Bydgoszczą, na obszarze słabo zurbanizowanym i uprzemysłowionym. Stwierdzono, że wyniki charakteryzujące zmienność średniej temperatury powietrza w Mochełku można uznać za reprezentatywne dla rejonu Bydgoszczy. Średnia temperatura powietrza w rejonie Bydgoszczy charakteryzowała się, zwłaszcza w miesiącach zimowych, bardzo dużą zmiennością czasową, właściwą dla umiarkowanego i przejściowego klimatu Polski. W latach 1949–2008 średnią temperaturę powietrza okolic Bydgoszczy w 3 spośród analizowanych 13 kroków czasowych (maj, sierpień oraz cały rok) cechował wzrost wraz z upływem czasu. W odniesieniu do średniej temperatury rocznej, wynikało to głównie z wystąpienia serii cieplejszych lat 1989–1994, w których temperatura powietrza była wyższa o około 20% od warunków przeciętnych. Twierdzenie o ocieplaniu się klimatu okolic Bydgoszczy należy traktować z dużą ostrożnością ze względu na różne równania trendów liniowych z dominacją równań nieistotnych oraz stwierdzony brak nasilenia się w ostatnim piętnastoleciu okresów o anomalnych i ekstremalnych warunkach termicznych.
The aim of this study was to present the courses of mean monthly and yearly values of air temperature in the Bydgoszcz area with special attention paid to their tendencies over 1949–2008. Due to the problem of warming of Poland’s climate, which has been widely raised and lively discussed, particularly in recent years, air temperature characteristics in the whole 60-year research period (1949–2008) and the recent 15-year period (1994–2008) were also compared. For elimination of an antropogenic effect of a city, temperature measurements took place in Mochełek that is a slightly urbanized and industrialized area placed near Bydgoszcz. On the base of the multi-year research it was found that results of mean air temperature varaiability in Mochełek are typical for the Bydgoszcz area. The mean air temperature ecpecially in winter months was typical of the temperate and transitional climate of Poland. In the period 1949–2008 the mean air temperature of three of analized thirteen timesteps (May, August and a year) were characterized by an increase with time. In case of a mean annual temperature the increase resulted from occurance of warm years series in the period 1989–1994 when the mean air temperature was higher by about 20% than those of average. A statement that the climate is getting warmer should be threated with caution due to different trends of linear equations that are dominated by insignificant equations and also due to stated the lack of severity of anomalous and extreme termal conditions in the last fifteen years.

Opis:
The projected effect of climate change is the increase of both the frequency and intensity of extreme weather events. An attempt has been made to study the extremes in temperature over two regions of India i.e. North-East Region (NER) and West Coast Region (WCR). A detailed analysis indicated that in the NER, ten stations indicate increase in annual extreme minimum but significant at four stations. Post-monsoon season is very predominant where five stations show significant increase. In the WCR, all the stations indicate increasing trend in annual extreme maximum temperature significant at nine stations. Majority of the stations indicate significant increasing trend in all the seasons except monsoon season.
