Monsoon or rainy season, lasting from June to September. The season is dominated by the humid southwest summer monsoon, which slowly sweeps across the country beginning in late May or early June. Monsoon rains begin to recede from North India at the beginning of October. South India typically receives more rainfall.
What months do monsoons happen?
It usually happens between April and September. As winter ends, warm, moist air from the southwest Indian Ocean blows toward countries like India, Sri Lanka, Bangladesh, and Myanmar. The summer monsoon brings a humid climate and torrential rainfall to these areas. India and Southeast Asia depend on the summer monsoon.
What is the period of monsoon in India?
The Indian summer monsoon typically lasts from June-September (Fig. 58d), with large areas of western and central India receiving more than 90% of their total annual precipitation during the period, and southern and northwestern India receiving 50%-75% of their total annual rainfall.
What is the main cause of monsoon in India?
What Causes the Monsoon in India. The monsoon is caused by differing temperature trends over the land and ocean. During the monsoon, the wind direction reverses. Moisture-laden winds from the Indian Ocean come to fill up the void, but because they cant pass through the Himalayas region, theyre forced to rise.
What are the causes of monsoon wind?
The monsoon is caused by the differences in the temperatures of the ocean and continental wind currents. The heat from the sun heat up the oceanic water and results in the generation of air under high pressure that in the form of large air mass undergoes convection and creates low pressure near the surface of land.
How do monsoons affect people?
During summer monsoons, heavy rainfall can cause flooding. Powerful floodwaters can drown victims and damage buildings, leaving people without homes and vulnerable to the elements. During the 2014 summer monsoon in Pakistan and India, nearly 300 people lost their lives during landslides and home collapses.
What is the main cause of monsoon?
The primary cause of monsoons is the difference between annual temperature trends over land and sea. The apparent position of the Sun with reference to the Earth oscillates from the Tropic of Cancer to the Tropic of Capricorn. Thus the low pressure region created by solar heating also changes latitude.
How long does a monsoon last?
Just for reference: Based on the dew point method, the monsoon would usually start, on average, around July 7 and conclude approximately two months later, soon after Labor Day.
