Structure and Dynamic of Meteorological Fields on the Asian Region of Russia in the Period of the Global Warming for 1975-2005

In this study for the Asian region of Russia (ARR) using observation data of 1975-2005 the analysis of temperature, pressure and precipitation fields was done. As average fields of these values, as fields of its linear trends for selected time interval were calculated. It is established that for 1975-2005 it was the warming on this territory during all calendar months of year, except December. The consistent estimates of the warming trends, averaged by territory, for March, May-August and October with magnitudes of trends, averaged by territory, in the interval from 0,37 to 0,65 ºС/10 years were obtained. Change of average annual magnitudes of temperature was 0,34 ºС/10 years with standard deviation of 0,20 ºС/10 years. The pressure field is characterized by negative trends during all months, except July, August, November and December, when change is absent (July, August) or it is weakly positive (November, December). For average annual pressure the estimate was found -0,22 hPa/10 years with standard deviation 0,17 hPa/10 years. The tendency to the reduction of precipitation in some calendar months and for the year in general was established, but the magnitudes of trends do not exceed its standard deviations.
