Abstract: Relevance. Studying of spatial distribution of evaporation from water surface is becoming a rather topical thing in the conditions of the observed clime changes. In this connection it is quite evident that the use of more precise methods taking into account all diversity of natural factors of the above process formation is necessary Methods. We used the re-analysis methods to extend the database for the evaporation spatial generalization. These methods are based on the use of physical/mathematical model of vertical hydrothermal transfer in water medium. The model was calibrated according the data of observations of evaporation with GGI-3000 at 35 plots of the central part of the European territory of Russia. Results. We have calculate average ay-year values of evaporation from water period over the 2000–2020 period according to data on average daily values of meteorological elements on a spatial network at the plots of 105 meteorological stations. The maps of evaporation distribution for the central part of the European territory of Russia have been plotted. Results of spatial modelling were generalized and we obtained a number of regularities connecting the value of average many-year evaporation from water surface with air temperature and wind speed of the warm season. We have analyzed the variability of the transition coefficients from the evaporation value gauged with GGI-3000 to the evaporation from the small water bodies surfaces and have stated that they are subjected to climatic changes.
