The rainy season in India
India is an agricultural country and Indian agriculture is dependent on monsoon. Every year millions of farmers wait for rains for a good harvest.
Indian monsoon begins in the month of June and stays till mid-September.
Let us discuss more about the rainy season
The low pressure condition formed over the northern plains in the summer intensifies with time. By June, it reaches a maximum point.
This low pressure attracts the southeast trade winds towards the northern plains.
These winds, originating over the sea, carry moisture, and enter the peninsular region as southwest monsoon winds.
It takes about a month for these winds to envelop the entire country.
After months of scorching heat, people of India get relief, thanks to the rains!
These southwest monsoon winds change India’s weather totally.
The western ghats end up receiving more than 250 cm of rainfall during early June.
The maximum amount of rainfall is received by northeast India.
Cherrapunji and Mawsynram receive some of the highest average rainfall in the world.
Gujarat and Rajasthan, receive very little rainfall.
Breaks in rainfall
The monsoon rains only take place for a few days at a time.
Days of constant rainfall are followed by dry days.
These breaks in rainfall occur due to the movement of the monsoon trough.
The axis of the trough keeps moving up and down. When it is above the northern plains, the region receives good rainfall.
When this axis moves closer to the north, the plains experience dry weather, while the Himalayas receive widespread rainfall.
This axis of the trough determines the distribution of rainfall in the country.
The devastating effect of monsoon
When the rains fall over the Himalayas, these usually end up flooding rivers that eventually flow through the northern plains.
These floods end up causing great loss to life and property in the plains.
The frequency and intensity of tropical depressions also dictate the amount of monsoon rains.
Excess of everything is bad. Too much monsoon rain ends up harming people.
The monsoon is also known for its uncertainty.
As we have seen, it can cause widespread floods and devastation in some parts.
In some places, it can cause drought-like situations, where monsoon does not arrive soon enough.
The irregular schedule of monsoon also ends up disturbing farming cycles also.
Let us revise
The Indian monsoon or rainy season sets in around June.
The southeast trade winds enter India as the southwest monsoon, and bring in rains.
These winds carry moisture as they originate over oceans.
Northwest India receives the most amount of rainfall.
Monsoon can also be cause of destruction in many places, some due to floods, some due to droughts because of irregular monsoon.
