Abstract

The spatiotemporal variability of temperature in the atmospheric boundary layer has been studied comparatively in the city of Tomsk (Russia) and in the coastal zones of Lake Baikal and Lake Issyk-Kul. Measurements with an MTP-5 temperature profiler have shown that the conditions of thermal stratification of the lower 1-km air layer strongly differ in summer under urban conditions in the absence of large water reservoirs nearby and in the mountain areas on the coasts of big lakes. The types of stratification and parameters of the atmospheric boundary layer in the regions under study are detsermined.
