| Abstract: | Summary A quantitative study of the balance requirements of the atmosphere's kinetic energy during normal winter conditions is made for the whole Northern Hemisphere and separately for the tropics (0–30°N) and the extratropics (30–90°N) by using different sources of data. The most important new finding is a demonstration of the existence (on the isobaric surfaces) of meridional eddy flux of potential energy; this flux approximately counterbalances the meridional flux of kinetic energy. One of the conclusions reached is that maintenance of the large-scale eddies in the tropics is mainly due to forcing by extratropical eddies. This forcing occurs at 30°N as a southward eddy flux of potential energy. |
