Meteorological conditions and their seasonal distribution in the Gushary gorge of the Varzob river basin (Tajikistan)

Abstract

The results of monitoring meteorological conditions in the middle part of the Varzob river basin in the Gushary gorge are presented. It is shown that for the period 1946–2021, atmospheric precipitation remains almost constant and the average annual temperature is characterized by an increasing trend. The seasonal distribution of temperature and atmospheric precipitation in the Gushary gorge of the Varzob river basin is characterized by the fact that the maximum precipitation corresponds to the spring season with maximum temperature in the summer season. It has been established that the average long-term temperature in the summer season in the Gushary gorge does not exceed 25°C that is due to the protection of the gorge from the penetration of air masses by high mountain ranges. A study and comparison of evapotranspiration in the gorge for 1950 and 2021 showed that for the period of more than seventy years there have been no significant changes in evapotranspiration.
