Abstract
Charney’s equation for a non-divergent barotropic model has been applied to a depression in the Bay of Benegal. The equations were solved by relaxation method, and the predicted height changes were compared with those observed. The agreement was not discouraging, although there was considerable room for improvement.
The limitations of the above model, specially in low latitudes, is discussed with special reference to the non-barotropic nature of the atmosphere and the quasi-geostrophic approximation.
