    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:
    W opracowaniu scharakteryzowano przebieg warunków pogodowych podczas XXVI Wyprawy Polarnej Uniwersytetu Marii Curie-Skłodowskiej na Spitsbergen. Pomiary wykonywano od 8 lipca do 1 września 2014 roku za pomocą automatycznej stacji meteorologicznej zainstalowanej w Calypsobyen (Bellsund, Svalbard). Analizie poddano temperaturę i wilgotność względną powietrza na wysokości 200 cm nad powierzchnią gruntu (n.p.g.), temperaturę powietrza przy gruncie (5 cm n.p.g.) oraz prędkość i kierunek wiatru. Uzyskane wyniki zostały porównanie z danymi, dla okresu wspólnego, z dwudziestu sezonów pomiarowych z lat 1986-2011 tj. od 10 lipca do 25 sierpnia.
    Arctic is an area which rapidly react on the changes in environment. The weather conditions react the most quickly and determine other changes in geosystem. That is why the meteorology is the subject not only for meteorologist and climatologist but also for other researchers (like geomorphologists, hydrologists) and makes the background for their research in polar region. The region of Wedel Jarlsberg Land (western coast of Spitsbergen) has been a field of taking research by scientist from the Maria Curie-Skłodowska University (Lublin) for almost 30 years. Meteorological observations were carried out since 1986. At the beginning, measurements were taken every 3 or 6 hours. Since 1999 measurements have been doing by automatic stations taking measurements with 10 minutes time step (144 times per day). The aim of this paper is to present course of meteorological conditions during the XXVI Expe-dition of UMCS to Spitsbergen in 2014 on the background of multiyear 1986-2011. The station was located on Calypsostranda, a flat sea terrace, at the height of about 23 m a. s. l., at a distance of 200 m from Bellsund Fjord and 2 km from the Scott Glacier. The substratum was made of dry lichen-moss tundra. In 2014, the meteorological investigation began on 8th July and ended on 1st September. The mean daily air temperature at the altitude of 200 cm amounted to 5.9°C throughout the measurement period. The highest mean daily temperature (8.4°C) was recorded twice: the 23rd July and 4th August. The lowest mean daily temperature (3.1°C) was recorded the 31st August. Mean daily air temperature at the altitude of 5 cm also amounted to 5.9°C. The highest temperatures are recorded around 12 UTC, and the lowest just before midnight. In the 5-18 UTC temperature at 5 cm is higher than the temperature at 200 cm. The highest maximum temperature at the altitude of 200 cm (12.2°C) and at the altitude of 5 cm (14.0°C) was recorded the 4th August. Minimum temperature at the altitude of 200 cm (1.5°C) was recorded the 27th August and at the altitude of 5 cm (-1.7°C) the 25th August. The mean daily relative humidity at a height of 200 cm above the ground amounted to 85% and only twice (4th and 24th August), the humidity dropped below 60%, which was associated with the presence of foehn from the East. For the whole measurement period, the total precipitation amounted to 38.6 mm. 17 days with a precipitation ≥ 0.1 mm were observed (which means that rainfall occurred in 30% of the days). The highest rainfall amounted to 9.6 mm and occurred on 10th July when the air temperature at the altitude of 200 cm decreased from 10.2 do 5.6°C and the weak south wind changed direction to the west, and his speed increased to more than 7 m∙sˉ¹. The mean wind speed was 3,6 m∙sˉ¹ throughout the season. To compare selected meteorological weather conditions of the summer season 2014 against the multiyear 1986-2011, based on data for the period that is common (10th July – 25th August). The mean daily air temperature in 2014 was up to 1.1°C higher than the average temperature of period 1986-2011. Only season of 2002 was characterized by higher average temperature (6.3°C). The sum of the 2014 season precipitation was lower than in multiyear. The mean daily wind speed of season 2014 was 3.6 m sˉ¹ and was lower only by 0.7 m ·sˉ¹ from the mean of multiyear. During the season 2014, the winds from W were dominated (25.7%), while its frequency in other seasons does not exceed 5-10%.

    Opis:
    Arctic, especially western coast of Spitsbergen has been a field of taking research by scientist from UMCS and AR in Lublin for more than 15 years. Researches have been taken there are connected with earth sciences like: meteorology and climatology, geomorphology, hydrography, geology and agriculture and botany. Meteorological observations were steady point of researches taking on every UMCS?s trips in Spitsbergen. At the beginning, at the 1986-1988 seasons were very wide, and measurements were taken every 3 hours. Between 1989 and 1999 measurements were taken 4 times a day a.e. every 6 hours. Since 1999 measurements have been doing by automatic stations. Appliance this equipment let us taking measurements with 10 minutes time step. The aim of this paper is to present course of meteorological conditions during the scientific trip to Spitsbergen in 2001 at the background of period 1986-2000. There were made comparisons of course mean daily four meteorological elements as: air temperature measured at 200 cm height [°C], wind speed [m/s], cloudiness, and precipitation [mm] from 2001 season with data collected during 15-years UMCS geographical trips on Spitsbergen. We can make statement that in thermic season 2001 was a bit cooler (0.1°C) than the period 1986-2000. At that season variability of mean daily temperatures was lower than in period. The lowest mean daily temperature was 2.5°C, and all days in period 2001 were lukewarm. The rate of mean daily cloudiness in period 1986-2000 is compensated. 2001 season was the same as other seasons during period. The air masses are strongly modified by circulation and orography. Season of 2001 was featured by lower mean daily wind speed (3.2 m/s) than in the period ? 4 m/s, also highest mean daily wind speed in 2001 was lower than in period 1986-2000. The greatest variability of four analysed elements on that period has precipitation. The variable of this element exceed 71.7 mm, which we can express as a ratio 1 to 20. 2001 season was dryer than mean of period about 11 mm.
