Isobars in the tropics - some basic ideas of Tropical Meteorology

Abstract

The subject of Tropical Meteorology is of late assuming importance to be dealt with theoretically. Meteorological network is also being developed. It is shown that even in the tropics, in the region of steady winds and small pressure gradients, the isobars follow the wind directions. Taking the idea of streamlines and isobars at upper levels in higher latitudes, methods of drawing isobars are given. This is particularly important, as due to small pressure gradients in the tropics, there is great latitude in drawing isobars and some almost ignore the pressure values. Methods of drawing conclusions from meteorological facts are given.
