Atmospheric precipitation as a source for the formation of surface water resources of the desert zone

Abstract The purpose of this article is to scientifically substantiate the metrological aspects of the possible volumes of surface runoff throughout its entire territory, which could be used in the interests of agricultural production. The article discusses the monthly norms of atmospheric precipitation at the meteorological stations of the Kyzyl Kum desert. It has been determined that in the Kyzyl Kum desert up to 75% of atmospheric precipitation falls in liquid form. Accordingly, the share of solid and mixed precipitation accounts for about 25%, and this ratio regularly changes with the movement from north to south. At present, the conditions for the formation and regularities of the spatial distribution of surface water resources of the Kyzyl Kum desert are unknown and, in the author’s opinion, it is economically inexpedient to neglect them, especially in dry years. The study used the most developed method of correlation functions to estimate the possible error in extrapolating the sum of atmospheric precipitation to a given area, but with respect to the entire set of meteorological stations available in the Kyzyl Kum desert. The results of the study showed a high stability of the ratios of monthly and maximum daily amounts of atmospheric precipitation. This stability takes place both in relation to the entire spring time and throughout the entire area of the Kyzyl Kum desert. Such stability and calculated ratios make it possible to roughly determine the daily precipitation amount, having only data on their monthly amount.
