Abstract: 

The research results of the meteorological characteristics and evapotranspiration dynamics in the middle reaches of the Varzob river, a tributary of the Kafernigan river, for the period 1946–2021 are presented. It has been established that temperature is a more active factor in the processes of evapotranspiration. A slight trend of decreasing precipitation at altitudes up to 400 m a. s. l in the southern parts of the Varzob river basin is associated mainly with local meteorological phenomena and is in no way related to the processes of penetration of external air masses into the river basin, since the correlation coefficient of atmospheric precipitation values in the upstream (Maykhura weather station) and in the downstream of the Varzob river basin (Ayvaj weather station) is very little (0.1).
