Polish Antactic Station H. Arctowski is located at King George Island (South Shetlands, Antarctica) near the Admiralty Bay (Φ=62°10'S, λ=58°28'W). Measurements and meteorological observations were recorded tour times per day (00, 06, 12, 18 GMT). In this paper the weather conditions at the vicinity of the Arctowski Station in 1998 are characterised by air temperature, air pressure, wind speed and direction, relative humidity, total cloudiness, sunshine duration, pecipitation. Year 1998 can be defined as abnormal warm, the mean annual air temperature was -0,7°C and in comparison with the multiyear average (1978-1989) was higher by 0,9°C. Positive anomaly was detected in ten months of year. In comparison with the multi-year average of air pressure (988,5hPa), wind speed (6,0m/s), cloudiness (6,1) this year had lowest values (Table 1 ). The insolation conditions were very bad, the number of hours with sunshine reached 712,3 (long term average sum of sunshine duration is 896,0 h). In 1998 winds from SW and WSW were the most frequent (14,3%) cooling down and intensive precipitation were connected with this wind circulation. However the greatest air temperature falls corelate with eastern winds (8,6%). High frequency of wind direction in 1998 was W (9,3%), N i NNW (8,8%) and SE (8,4%) too. Relative humidity was 82,1% and corelated with average for a long time period 1977-1989. Atmospheric precipitation was higher of the average long term sum. The permanent snow cover maintained from June until the middle of November, and its maximal thickness was 93,3 cm in September.

The article presents results of meteorological observations carried out in the summer of 1998 on the Kaffiöyra Plain during XVth Toruń Polar Expedition organized by the Geography Institute, Nicholas Copernicus University of Toruń. The measurements were carried out tour climatological time a day (01,07, 13 and 19 LMT) from 20th July to 2nd September 1998 i.e. 45 days. The values of meteorological elements are presented in Tab, 2 and Fig. 2. Apart tram the 1998 summer data, there have also been presented for comparison mean values of basic meteorological elements from comparable periods (July 21-August 31) of all the summer seasons when the Toruń Polar expeditions operated on Spitsbergen (Tab. 4).
