In this paper a study has been made of available potential energy and its transformation into kinetic energy of the different weather systems for the region of south Asia for the typical monsoon month of July 1963. Energetics of the standing eddies and transient eddies have been separately computed. Interactions amongst themselves and with mean zonal flow have been studied
It is inferred that zonal current is the source of available potential energy for both standing and transient eddies; standing eddy is the source of kinetic energy for zonal current and transie1lt eddies, However, when the region of monsoon trough is considered, standing eddy gains kinetic energy from transient eddy suggesting the importance of monsoon depressions in strengthening the monsoon trough, Available potential energy is converted into kinetic energy in the cases of both zonal current and the standing eddy, The generation of available potential energy and the energy advected into !he area of interest, together exceed the losses due to dissipation of kinetic energy.
