Summer And Winter Monsoon

Let's learn what "MONSOON" is.

In summer we have hot winds blowing. So we feel very hot and sultry.

In rainy season we have winds blowing from the oceans, along with clouds. So we get heavy rainfall.

In winter we have cold, dry and snowy winds blowing from the Himalayas.

This seasonal shift of the winds is called the MONSOON. In Arabic, it is commonly called MOUSAM.

Monsoons always blow from cold to warm regions. Here arise two types of monsoons, namely, Summer Monsoon and Winter Monsoon

Let us briefly discuss these two types of monsoon. First, we will study about summer monsoon then winter monsoon.

Summer Monsoon

In summer the sun heats up the land more than the water in the ocean.

The land heats the air above it and the hot air rises rapidly and to fill the void the cold air in the ocean rushes towards the land. This completes a cycle.

There are rain clouds over the oceans. So the rain clouds come along with the rushing cold air. these are called monsoon clouds.

These monsoon clouds are full of moisture and can produce heavy rainfall for a long time. This is the rainy season.

This heavy rain after the summer season is what we call Summer Monsoon.

During the summer monsoon, The wind blows from the Indian Ocean, and the heavy rain lasts from roughly from April to October.

In India, Cherrapunji is the most affected region by Indian Summer Monsoon.

But it is also a tourist attraction place in India.

Winter Monsoon

In winter, the land is colder than the sea, therefore the density and the pressure of the air above the land will be higher

As a result, cold dry winds blow out across the country.

This air while blowing from land to sea, absorbs water vapour from the land surface, causing rainfall over the ocean surface

In India, the Himalayas prevent much of the wind and moisture of the winter monsoon from reaching the inner land.

So winters are a little less severe in India. We mostly get only snow. If there were no Himalayas there would be blizzards.

But winter monsoons cause droughts because the air is dry.

Revision

Monsoon is a seasonal change in the direction of the prevailing, or strongest, winds of a region

Most of the time during summer, the land is warmer than the ocean. This causes the air above the land to rise and air to blow in from the ocean to fill the void left by the air that rose.

Rising air leads to cloud formation

These monsoon clouds that formed are full of moisture and can produce heavy rainfall for a long period of time

This heavy rain during summer is what we called Summer Monsoon. In India, Cherrapunji is the most affected region by Indian Summer Monsoon

In winter monsoons, a large amount of cold dry air blows out from the continent towards the oceans

In India, winter monsoons are less powerful than summer monsoons as the Himalayas prevent much of the wind and moisture of the monsoon from reaching the coast.
