The paper presents the results of meteorological measurements carried out in the Kaffioyra Plain in the summer season of 2001 and in the period form July 2001 to April 2002. The main meteorological observations were conducted in N.Copernicus Polar Station. situated in northern part of the Kaffioyra (NW Spitsbergen). The paper also presents the results of snow accumulation measurements on the Waldemar Glacier and Irene Glacier. which are located at Kaffioyra Region. The mean air temperature in the summer period (21.07. to 31.08.2001) was 5.9°C and was visibly higher then the long-term average. The sum of precipitation in this time was 37 mm and was lowest then the long-term average. The comparison between summer season 2001 and mean values from the years 1975-2001 in the common period shows that this season was characterised by air temperature higher then many year?s values. The mean air temperature in the period from July 2001 to April 2002 was -5.3°C. The highest monthly air temperature was in August (5.2°C) and the lowest was in March (-14.7°C). The sum of precipitation in the time with snow cover at Kaffioyra was 86.6 mm. Investigations of a snow cover on the Kaffioyra have been carried out in two points. Snow cover on the Kaffioyra was started to form in the end of September. Winter snow accumulation equal to 91 cm in point B and 18 cm in point B. The changes of snow thickness was depended from a velocity of wind. Investigations of a snow cover on the Waldemar Glacier and the Irene Glacier have been carried out form September 2001 to April 2002. The Waldemar Glacier and Irene Glacier are located in the northern part of the Oscar II Land (Northwestern Spitsbergen). In spite of small areas of these glaciers. there is great spatial variation in snow deposition. During the winter 2002 the highest snow accumulation of the Waldemar Glacier was noted in the northern part of the glacier. both on its accumulation part and at foot of Grafjellet which surrounds the glacier from the south. The lowest thickness of a snow cover was observed at terminus of the glacier and at foot of the medial moraine (up to 40 cm w.e.). On the Irene Glacier the highest snow accumulation was observed in two accumulation parts (up to 120 cm w.e.). The lowest thickness of a snow cover was observed at terminus of the glacier and at central part of glacier (up to 20 cm w.e.). Winter snow accumulation of the Waldemar Glacier was equal to 63.2 cm w.e. On the Irene glacier it was similar and equal to 64.7 cm w.e.
