Eolian processes and some elements of King George Island climate such as air pressure, temperatures, humidity and winds have been discussed in the paper. The main and indispensable factor generating the eolian processes in this area is strong wind the average speed of which amounts up to 8 m/s. The geological structure, mainly Tertiary rocks of volcanic and sedimentary origin also enhances the eolian processes. It has been stated that the greatest amount of loose material was transported in the air streams at the height of about 0.5-0.8 m above the ground level and at the same time it was the coarsest material. It is possible to suggest that air stream of 1 m2 in diameter and 8 m/s of speed may transport as much as 22 g of sediment per day. The greater part of material blown away is transported by air and then accumulated on the icy, snowy or sea areas.
