Analysis estimates available and kinetic energies in the Southern Hemisphere, suggesting distinct energy spectra patterns.
Estimates of total zonal and eddy available potential and kinetic energies deduced from daily Southern Hemisphere mean sea level pressure and 500mb geopotential height fields for the eighteen months of the International Geophysical Year are presented. The eddy energies are further subdivided into components associated with eddies of longitudinal wave numbers one to twelve. The results are compared with similar estimates for the Northern Hemisphere. The eddy energies appear to be partitioned into distinctly differing spectra at wave number 7 and a power law E = bnα is postulated for the higher wave number spectra as has been done for the Northern Hemisphere. Estimates of α are made for each energy for the winter, summer and annual mean spectra.
