The variability of radiative balance elements and air temperature over the Asian region of Russia

[摘要] The variability of spatial-temporal distribution of temperature and heatbalance elements is investigated for the Asian territory of Russia (45–80° N, 60–180° E) using JRA-25, NCEP/DOE AMIP-II reanalysis data andobservational data for the period of global warming 1979–2008. It is shownthat temperature trend over the territory is 1.4 °C for the period understudy according to reanalysis data. Since the beginning of 90s of 20thcentury the increase of back earth-atmosphere shortwave radiation isobserved. Such tendency is in conformity with the cloud cover distributionand downward shortwave radiation at the surface. Regression model describingtemperature variability with variability of heat balance elements waspresented. We conclude that possible applications for the model include theconvenient estimate of temperature variability according to reanalysis data.
