Paper presents results of investigations on temperature inversions, carried out during XIX Antarctic Expedition PAS in 1995, Temperature values taken from thermograph readings at Arctowski Station (3 m asl) and Point Thomas (173 m asl, situated 850 m, WNW from Station) were used to find periods of time with temperature inversions, Seven cases, analysed in this paper. Were selected as deep inversions (mean temperature gradient counted from hourly values was higher than 1°C/100 m), All presented inversions were radiation type, accompanied by calms and relatively small total nebulosity, except three cases, when nebulosity was the effect of inversion Influence of local orographic conditions on deepening temperature inversions is strong, but the main factor for it's forming is anticyclonic situation in the region of South Shetland Islands (accompanied by calms) and sea ice conditions. All analysed inversions were fonned during months with fast ice cover existence in Admiralty Bay and very close ar close ice fields on Bransfield Strait. In other ice conditions deep temperature inversions were not recorded, Minimum air temperatures at Arctowski Station recorded in July, August and September 1995 were measured during inversions. Maximum difference in air temperature between Point Thomas and Arctowski Station was recorded on July 22 (l4°C), These cases let to make conclusion, that probably all extremely low temperatures recorded during severe winters at Arctowski Station were measured in inversion conditions.
