A study is made of the influence of the large-scale atmospheric circulation, described by the indices of Northern Hemisphere Teleconnection Patterns, on air temperature and ice-thermal characteristics of Lake Baikal for the time interval 1950–2010. Multiple linear regression equations have been obtained to account for 46–47% of the air temperature changes during the winter, spring and autumn seasons, and for 18% during the summer season. The main contribution to air temperature change for separate seasons (except in the summertime) and ice-thermal characteristics is made by the fluctuations of the AO and NAO indices characterizing the west-east transport of air masses, and of the SCAND and Sh indices of the mechanisms blocking this transport.
