EVALUATION OF THE CALCULATED HYDROLOGICAL-CLIMATIC METHOD OF EVAPORATION FROM THE SOIL SURFACE

The article provides a quantitative assessment of the Mezentsev method for calculating evaporation from the soil in comparison with the data measured by the GGI-500 weight evaporator. The results of calculating the provision of the maximum amounts of annual evaporation based on empirical data in comparison with similar ones using gamma and binomial distributions are presented. It is shown that these distributions can be successfully used to calculate the provision of the maximum amounts of annual evaporation in the territory of Uzbekistan. The constants included in the Mezentsev formula for calculating evaporation from the soil to obtain greater accuracy, it is better to obtain for the study area on the basis of the least squares method using data measured by evaporators. In general, it is concluded that the analytical method for calculating evaporation from soil, proposed in the mid-50s of the last century by V.S. Mezentsev, can be used in various fields of agrometeorology, it is especially convenient when developing mathematical models of evapotranspiration.
