Transfer of Sensible Heat by Transient Eddies in the Atmosphere on the Southern Hemisphere: An Appraisal of the Data before and during FGGE

Abstract

Although the numerical, daily operational analyses for the Southern Hemisphere, in particular those made in Australia since 1972, can be used to describe large-scale features in time and space, they are not suited to computations of quantities which rely for their accuracy on the correctness of the daily analysis at individual points. This conclusion is based on the analysis of transfer of sensible heat by the transient eddies during FGGE and the years 1972?77. In addition, the Australian daily operational analyses of the Southern Hemisphere were compared with those of the U.S. National Meteorological Center, and it was found that the former are generally the better ones.
