Annotation In recent decades there have been significant climate changes that lead to a pronounced response of the most sensitive parameters of the environment. As indicators of long-term climate variability, drainless lakes can act, the morphometric characteristics of which are directly related to the conditions of humidity. On the territory of the Transbaikal Territory, drainless lakes are located mainly in the Torey Plain, whose steppe areas are an important breeding and feeding area for a significant number of numerous species of migratory waterfowl and important populations’ support of rare and endangered species. Therefore, in a changing climate, it seems important to study the long-term changes in the moisture content of the territory of the Torey lakes location, using actual data. The analysis of humidification conditions of the territory is based on the mean monthly air temperature and monthly precipitation, as well as on the calculated parameters of aridity and humidity. It is concluded that the territory of the Torey Lakes location is characterized by insufficient atmospheric moisture and the largest potential evaporation in the Transbaikal Territory, which are due to the high values of wind speed here and the duration of sunshine. In general, the values of the humidification coefficient reflect the steppe conditions of the investigated territory. According to the average values of the GTK for the period May-September, the area under study is characterized by optimal humidity conditions, and by average values of the Pedya index – normal. Due to the observed climatic changes in the region of the Torey lakes location, there was a decrease in the humidity of the territory as a result of increased evaporation, which, in turn, is associated with an increase in air temperatures, taking place against a background of cyclical precipitation, typical of the steppe conditions of the study area. Taking into account the fact, that during the last 10 years there has been a pause in global warming and a high-water phase of the cycle has come, we can assume that the current climate situation may change, as a result of which, in the near future, the moisture resources in the investigated area will increase
