Empirical forcing functions for the large-scale mean disturbances in the atmosphere
Fundamental equations governing the forced response of the atmosphere to the fixed sources and sinks of heat and momentum are reviewed. Empirical forcing functions, computed from data for the winter of 1950, representing the effects only of the horizontal transient eddy transport field, are presented. These appear to be of the same order as is required to account for the observed mean conditions and, hence, should be included in the general theory of the mean state along with other diabatic and mechanical effects which have been considered previously.
