PRESSURE ANDCIRCULATION REGIME OF THEVOLGA FEDERAL DISTRICT
In this study the existential changes of the average monthly atmospheric pressure and wind fields and their interrelations in the territory of the Volga federal district, are considered. Calculations were carried out according to the measurements of 183 meteorological stations in the period of 1966-2009. The periodic (daily and annual) and non-periodic changes of pressure and wind is assessed. It is revealed that the average monthly atmospheric pressure and wind have non-uniform distribution on the territory and the general tendency of falling atmospheric pressure and weakening of wind streams. In this study the average sizes, characteristics of variability, anomaly of wind speed, linear trends, correlation communications and etc. are analyzed.
