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.
