Concept:The Indian Monsoon is called the South West Monsoon because the moist winds blow from the south-west direction towards the north-east direction during the monsoon season.
Explanation:The word monsoon comes from the Arabic term "mausim", which means season.
During summer, the northwest plains of India heat up rapidly in May.
This intense heating creates a strong low-pressure area over the region.
By early June, this low pressure becomes powerful enough to attract the southeast trade winds blowing from the southern hemisphere.
These trade winds originate over the Indian Ocean and carry abundant moisture from the warm equatorial currents.
When these winds cross the equator, they get deflected and start flowing in a south-westerly direction.
After entering the Indian landmass, they move from the south-west towards the north-east.
Therefore, these winds are known as the South West Monsoon winds.
India receives most of its annual rainfall from these monsoon winds during this season.
So, the Indian Monsoon is called the South West Monsoon because the monsoon winds run from the south-west to the north-east direction.
Answer:Option B – Monsoon winds run through South-West to North-East direction.
