Abstract

This paper continues the description of the connection between transport of sensible heat by eddies in winter and temperature, wind and pressure. The emphasis is on the transport by the quasi-stationary eddies, and we demonstrate that when this transport is strong in the latitudes near 50°N, the west wind tends to be strong in the subtropics at all levels in the troposphere and to he weak at middle and high latitudes, and vice versa when the stationary eddy transport is weak. These associations stem principally from the regions of the two major troughs. We show, in addition, that the stationary-eddy transport in the two troughs is negatively correlated; and we outline the teleconnections between the stationary-eddy flux over eastern Asia and pressure and temperature elsewhere.
