In earlier papers it was shown that tropospheric vertical wind shear in the layer 850–200 mb decreases appreciably prior to formation of depressions in the Indian summer monsoon area. Further analysis reveals that this decrease in shear stems almos

While mariners have, for long, associated monsoon with winds, description of monsoonal circulations over land has invariably been designed to explain primarily their rainfall effects. A rainfall oriented definition of monsoon bas several limitations.

Using correlation techniques, an assessment is made of the influence exerted by basic meteorological factors in controlling .the evoporative power of air. Linear regression equations are developed for twenty five stations linking pan evaporation with

Evaporation observations recorded with wire-mesh covered Class A pans at about 80 stations in India for, a period of five years or more have been used to present monthly and annual evaporations maps. Highest evaporation values of 16-17 mm per day are

Analysis of the causes of the Indian monsoon have concentrated on climatological phenomena in the southern hemisphere, such as El Nino and the Southern Oscillation. By contrast, we have examined meteorological records for the northern hemisphere (0°

DEPRESSIONS of the Bay of Bengal are an important component of the south-west monsoon circulation. Moving WNW, they account for much of the rainfall in India. Synoptic conditions favouring formation of monsoon depressions, so far described, are: (1)

Severe summer droughts of the Indian subcontinent have been found to accompany prolonged ‘breaks’ in the south-west monsoon. Data from the years of severe drought suggest that the associated breaks were due to upper tropospheric blocking ridges o
