Question

what is helley's view about monsoon??? plzz answer fast those u now only they can answer

Answer 1

The traditional idea of monsoon formation was developed in 1686 by English astronomer and mathematician Edmond Halley. In Halley's model, monsoons are viewed as giant sea-breeze circulations, driven by the differences in heat capacities between land and ocean surfaces that, upon heating by sunlight, lead to temperature differences between warmer land and cooler ocean surfaces,for example, between the Indian subcontinent and the oceans surrounding.He conceived the concept of the summer and winter monsoons. This concept dominated the scene for about three centuries.


The monsoons do not develop equally everywhere and Halley’s thermal concept fails to explain the intricacies of the monsoon. Besides differential heating, the origin and development of the monsoon is also influenced by the shape of the continent, orography and the conditions of air circulation in the upper Troposphere.

Nowadays, Halley’s theory has lost much of its significance, but it has not been out rightly rejected. The modern theories based on air masses and jet stream is becoming more relevant.

A monsoon is a seasonal shift in the prevailing wind direction, that usually brings with it a different kind of weather. It almost always refers to the Asian monsoon, a large region extending from India to Southeast Asia where monsoon conditions prevail. 

During the winter monsoon, a persistent and large high pressure zone over Asia drives cool, dry air soutward toward the tropics. This provides the monsoon region with its dry season. 

Then during May and June of each year, the summer monsoon arrives with persistent southerly wind flow driven by a warm air mass with low pressure at the surface that forms over southern Asia as it is warmed by the sun. Air from the relatively higher pressure air mass over the Indian and tropical western Pacific Ocean flows northward toward the low pressure over land, bring with it torrential rains. A late arrival of the monsoon can be bad for agriculture, as the monsoon rains are necessary for summer crops.
