Abstract: In this paper, the various spectral elements of 500 hPa height in the Southern Hemisphere are calculated using the 500 hPa grid point height from May 1972 to December 1987, including the monthly mean circulation, zonal kinetic spectrum, meridional kinetic spectrum, transport of the disturbance angular momentum, and the conversion rate from eddy kinetic energy to mean kinetic energy, under the condition of geostrophic approximation. The climate features of the spectral element are analysed, and it is found that the distribution of the first three waves (n=1, 2, 3) gives the fundamental feature of the general distribution, and the location and intentisy of the extreme spots are related to the season.
