- Despite being in the rain shadow area , the Deccan Plateau and parts of Madhya Pradesh also receive some amount of rainfall due to the influence of the advancing monsoon winds.
Detailed Answer by Teachoo
- The advancing monsoon is the period when the southwest monsoon winds move from the Arabian Sea and the Bay of Bengal towards the Indian mainland, bringing rainfall to most parts of the country. The advancing monsoon usually begins in early June and lasts till mid-July.
- The windward side of the Western Ghats, such as the coastal areas of the southwestern region, receives heavy rainfall exceeding 250 cm during the early monsoon season. This is because the Western Ghats act as a barrier and force the Arabian Sea branch of the monsoon to rise and condense, resulting in orographic rainfall. This region is also known as the Malabar Coast and has a tropical wet climate.
- Despite being in the rain shadow area, the Deccan Plateau and p arts of Madhya Pradesh also receive some amount of rainfall due to the influence of the advancing monsoon winds. The rain shadow area is the region that lies on the leeward side of a mountain range and receives very little or no rainfall. However, some parts of this region receive rainfall from the Bay of Bengal branch of the monsoon, which crosses over the Eastern Ghats and reaches this region. This region has a tropical wet and dry climate.
