SOME HEMISPHERIC SPECTRAL STATISTICS

Abstract

The results of computations of the spectrum of the eddy kinetic energy, the angular momentum transport, and the transfer of kinetic energy between the eddies and the mean motion, for the month of January 1949, are presented. The calculations are based on geostrophic winds measured at the 500-mb level. Of greatest interest is the finding that, for the month, disturbances of wave-number three were of singular importance as a source of the energy of the mean zonal motion.
