Summer Monsoon of southeast Asia

Introduction

Monsoon is known to be a wind reversal in a season accompanied by the changes that occur in the precipitation; today monsoon is described to be the change in the season and a change in the circulation of the atmosphere and precipitation which are associated with the asymmetric heating of the sea and the land. People call monsoon to be a rainy phase of the changing season, but looking at the grounds it has also been observed that there are dry phases also in the monsoon season. The major monsoons of the world are known to be the Asia- Australian and the West African monsoons. The word monsoon was first coined by the English in British India and neighboring countries, which described monsoon to be a big season, as the strong winds that blow during the monsoon season from the Arabian sea and the bay of Bengal, in the south west which bring heavy rainfall to every area that has to face the monsoon season. An uplift in the tibetian Plateau of Asia about 50 million years ago is known to be the cause of monsoon. May geologists think and believe that strong winds of monsoon began to blow about 8 million years ago which they have based on the records they found. Main Body

The sole reason for the formation of monsoon is because the sea and the land that warm up on the surface of the earth, and because of this there is no over lap between the geographical equator and the thermal. The thermal is not parallel with the latitude circles. The continents that are warm during the summers, the monsoon in those continents moves towards the north from the northern hemisphere, and in the southern hemisphere, it proceeds to south from the equator. It is because of the thermal equator the wind has to cross the geographical equator, and the earth which is rotating 24/7 changes the direction.

It is because of the wind of the south east trade of the southern hemisphere crosses the equator throught the northern hemisphere and then it carrier its movement towards the south western monsoon. The winds of the monsoon are caused seasonally which even fluctuate because of the warming up and cooling down of the land and the oceans that are nearby. Different air pressure arises because of this phenomena. It is during the winters that the land cools down, and because of these anti cyclones are formed in the centre. During the summers, the pressure of the air is quite opposite, and in those continents where the centre warms up, low pressure anti cyclonic areas form, this is what causes the air to blow from the sea towards the land and decreases the temperature during the nights.

It is the climate of India, Pakistan, and Bangladesh which are very much dominated by the season of monsoon. Monsoon seasons in these countries are very strong and can cause violent winds to blow which change direction with the ...
