Approximate solutions of radiative heating are developed using monthly mean radiative parameters and are combined with the geopotential and temperature fields to study the energetics of the Northern Hemisphere lower stratosphere on a daily basis for 1964. Significant leakage of energy from the troposphere occurs throughout the year and absorption of this energy in the lower stratosphere contributes to the maintenance of the eddies for all months except January. In winter there is significant transmission of tropospheric energy into the upper stratosphere which suggests a close coupling of the upper and lower atmospheres. The seasonal circulations are examined and it is found that the spring warming of 1964 was due to a period of enhanced convergence of tropospheric energy flux. In the fall absorption of tropospheric energy intensifies the flow. The role of radiation is to destroy available potential energy for all months of the year.
