Abstract:

We have performed correlation analysis of variations of the pressure and temperature fields during winter in the region of Central Asia. Comparison of the correlation fields with different time lags has allowed us to estimate the spatiotemporal scale of synoptic processes in the region of the Asian anticyclone activity. It was found that, in addition to the effect of arctic intrusions or their consequences, the processes from subtropical and tropical latitudes affect the region of Central Asia. Given the observed climatic tendency of increase in the heat content of oceans, the influence of southern circulations can lead to change of intensity of wintertime processes over Asia.
