【 摘 要 】

Despite the different attitude to this issue climate change in many parts of the world is obvious. It is known that all environmental factors interact with each other in a varying degree. It is expected that the change in climatic factors will be particularly noticeable in agriculture, in the field of water management. It is necessary to search for agricultural species that are adapted to the new conditions, for this it is necessary to determine the basic agroclimatic features of the terrain. Many scientists believe that they are the main factor in the location of crops. In this paper, based on hydrometeorological information on Kaliningrad weather station, the following indicators are sum of precipitation (annual and monthly averages), hydrothermal coefficient (mean multi-annual value, intra-annual distribution). The procedure for calculating such an indicator as the amount of precipitation for the period of active vegetation using modern information technologies is represented. The hydrothermal coefficient was determined by the method proposed by G.T. Selyaninov. The results of the reports make it possible to say that the values of the sum of precipitation for the period when the average daily air temperature exceeds 10 degrees Celsius significantly exceed the values that were set earlier and the hydrothermal coefficient remained almost unchanged. Also is detected the dependence between the hydrothermal coefficient and the productivity of cereals in the Kaliningrad region.
