W pracy przedstawiono przebieg warunków pogodowych w czasie XVII Wyprawy Geograficznej UMCS na Spitsbergen. Pomiary wykonywane były od 14 lipca do 31 sierpnia 2005 r. Obejmowały one następujące elementy meteorologiczne: temperaturę i wilgotność względną powietrza na wysokości 200 cm nad powierzchnią gruntu, temperaturę powietrza na wysokości 5 cm nad powierzchnią gruntu i temperaturę powierzchni czynnej, temperaturę gruntu na głębokościach 5, 10, 20, 50 cm, prędkość i kierunek wiatru, natężenie promieniowania całkowitego oraz UV (A+B), ciśnienie atmosferyczne. Pomiarów dokonywano za pomocą automatycznej stacji meteorologicznej (R-ASTER) z krokiem czasowym 10 minut. Dodatkowo określano stopień zachmurzenia nieba i rodzaju chmur oraz zjawiska atmosferyczne (o godzinie 00, 06, 12, 18 UTC). Ponadto raz na dobę (06 UTC) mierzono opad atmosferyczny i parowanie potencjalne.
Arctic, especially the region of Wedel Jarlsberg Land (western coast of Spitsbergen) has been the subject of a complex study carried out by the participants of Geographical Expeditions by the Maria Curie-Skłodowska University in Lublin for more than 20 years. The research into the meteorological conditions was initiated in 1986. In 2005, the meteorological investigation began on 14th July and ended on 31st August. 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. Mean daily air temperature at the altitude of 200 cm amounted to 4.9°C throughout the measu-rement period. The 28th August was the warmest day during the expedition. It was then that the highest mean daily temperature (7.5°C). The highest maximum temperature (9.4°C) was recorded the 24th August. The 17th July was the coldest day in the period, with a mean daily temperature of 2.8°C but a minimum temperature (0.9°C) was recorded the 20th of July. The mean soil temperature evaluated for the depths 5, 10, 20 and 50 cm was positive and varies between 6.0°C in the subsurface layer and 3.7°C in the deeper parts of the analysed profile. The mean relative air humidity was 85.8%. The highest relative humidity (97.1%) were recorded the 7th August. The 18th July was recorded lowest relative humidity - 72.2%. The precipitation total for the whole of the measurement period amounted to 56.7 mm. 26 days with a precipitation . 0.1 mm were observed (which means that rainfall occurred in 53% of the days), including 12 days with precipitation . 1.0 mm. The highest rainfall occurred on 28th July and amounted to 14.2 mm. Mean overall cloudiness amounted to 7.4 (on a 0-8 scale), and low cloud cover - to 5.4. Stratocumulus and Stratus clouds were dominant (60%). The mean wind speed was 4.0m/s. The highest wind speed was noticed 26th and 27th August - 9,4 m/s, but lowest wind speed (1.1 m/s) the 10th August. Dominated winds from East (22.9%) and from Northwest (19.2%). To summarise the summer season 2005 was a warmer, cloudier and wet than the period 1986-2002. - Źródło:
