2. Weather
3. Atmosphere
4. Climate

Answer 1

Correct Answer - Option 1 : Monsoon

The correct answer is Monsoon.

• The seasonal reversal in the wind direction during the year is known as Monsoon.
• Monsoon refers to the seasonal reversal in the wind direction during a year.
• Monsoon tends to have ‘breaks’ in rainfall; which means that there are wet and dry spells in between.
• The monsoon rains take place only for a few days at a time and then come to the rainless intervals. Seasonal reversal of wind direction takes place over the Indian subcontinent because in winter there is a high-pressure area in the north of the Himalayas & there is a low-pressure area over the ocean to the south. So cold and dry winds blow from the Himalayan region towards the ocean.
• In summer due to high temperatures, a low-pressure area develops over interior Asia as well as over northwestern India. This causes a complete reversal of the direction of the wind during summer and the rise of the Southwest monsoon.
• The bulk rainfall in India is received during the 4 months of the rainy season i.e June, July, August, and September. This is the period of Southwest monsoons blowing from sea to land. Only the Eastern coast of India receives some rainfall from the Northeast trade winds during the cold weather season.
