Measurements and meteorological observations at Hornsund were carried out in the frame of the 22nd Polish Polar Expedition "Spitsbergen 1999/2000" research work. This was the consecutive year-long expedition organized by the Geophysical Institute of the Polish Academy of Sciences. Circulation factors have a great influence on the meteorological conditions at Hornsund. The mean annual atmospheric pressure at the sea level (1005.0 hPa) was lower than its long-term average. The mean wind velocity was 5.8 m/s. There were 971.9 hours with sunshine. The analysed year was characterised by high air temperature as for the Arctic conditions. The mean annual air temperature was -3.7°C, and was 1.1OChigher then its long-term average. The analysis of the air temperature trend in the period 1978-2000 shows a systematic warming about 0.07°C/year on the southern Spitsbergen. The annual sum of precipitation was 500.9 mm, i.e. about 77 mm higher then the long-term average. In September the highest monthly precipitation sum (230.0 mm) was measured till now.

The article presents results of meteorological observations carried out in the summer of 1997 on the Kaffiöyra Plain during 13rd Toruń Polar Expedition. The measurements were carried out four climatological time a day (01, 07, 13 and 19 LMT) from 21st July to 1st September 1997 i.e. 43 days. The values of meteorological elements are presented in tab. 2 and fig. 2. Apart from the 1997 summer data, there have also been presented for comparison mean values of basic meteorological elements from comparable period s (July 21 - August 31 ) of all the summer seasons when the Toruń Polar Expeditions operated on Spitsbergen (tab. 4). The summer season in 1997 was very wet, with domination of strong winds and average sunshine, thermic and humidity conditions. During the research period cyclonic situations dominated (52.4%), on 47.6%, of the days the weather conditions were formed by anticyclones.
