In India monsoons create an entire season in which the winds reverse completely. The rainfall is a result of the convergence of wind flow from the Bay of Bengal and reverse winds from the South China Sea.
What causes monsoon rains in India?
The monsoon is caused by differing temperature trends over the land and ocean. … Moisture-laden winds from the Indian Ocean come to fill up the void, but because they can’t pass through the Himalayas region, they’re forced to rise. The gain in altitude of the clouds results in a drop in temperature, bringing about rain.
Why does it rain in monsoon?
However, when the air rises, and while it is still over the land, the air cools. This decreases the air’s ability to hold water, and this causes precipitation over the land. This is why summer monsoons cause so much rain over land.
How does India receive rainfall?
Most spectacular clouds and rain occur against the Western Ghats in India, where the early monsoonal airstream piles up against the steep slopes, then recedes, and piles up again to a greater height. … The windward slopes receive 2,000 to 5,000 mm (80 to 200 inches) of rain in the monsoon season.
Why do monsoons happen?
Water vapor condenses as air rises and cools in the ITCZ, forming clouds and falling as rain. The ITCZ can be seen from space as a band of clouds around the planet. This is where monsoon rainfall occurs. … The effect of Earth’s rotation on the winds is called the Coriolis effect or Coriolis force.
What weather is monsoon?
A monsoon is a seasonal change in the direction of the prevailing, or strongest, winds of a region. Monsoons cause wet and dry seasons throughout much of the tropics. Monsoons are most often associated with the Indian Ocean. Monsoons always blow from cold to warm regions.
Does it rain much in India?
Average annual rainfall is 300–650 millimetres (11.8–25.6 in), but is very unreliable; as in much of the rest of India, the southwest monsoon accounts for most precipitation.
What is the major 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.
Are monsoons dangerous?
Although the Monsoon brings welcome rains and relief from the summer heat, the thunderstorms that come with the Monsoon bring their own hazards. In fact, this is the most dangerous time of year weather-wise in the Southwest.
What are the advantages of monsoons?
- Monsoon rains give a good beneficiary for the farmers and agriculture.
- The rainfall helps in storing water for irrigation, electric power and drinking.
- A proper usage of monsoon leads to the prosperity for agriculture and everyone.
- Specific crops-rice and tea-depend only on monsoon rainfall.
