The entire life cycle of an intense monsoon depression which formed during the ISMEX period of 1973 was investigated by making use of the quasi-geostrophic baroclinic model. Vertical and meridional profiles of the vorticity associated with the system are presented. Large scale vertical velocity computed by the w-equation is also discussed. The kinetic and potential energies and the various energy conversion terms have, been evaluated. The flow diagrams relating to the energy conversion terms show that the energy conversions take place in the proper direction.
Radiosonde data from Soviet ships between Lat. 8°N and 12°N have enabled the detection of a closed low between 500 and 300 mb near about 10°N and 65°E. Vertical profiles of geostrophic vorticity and vertical I velocity associated with this system are also discussed.
