Describe the seasonal change in Earth's global circulation that produces the Asian monsoon

What will be an ideal response?


During the winter, the ITCZ is far to the south of Asia and the area is dominated by the prevailing NE tradewinds. These winds usher dry air from the interior of the continent into India and SE Asia, producing generally dry conditions. In the summer, as the ITCZ migrates north following the solar declination, the prevailing winds become southerly and carry moisture from the Indian Ocean into India and SE Asia. This moisture feeds into the ITCZ and creates plentiful rainfall, leading to a rainy summer season. In India, this effect is enhanced by the presence of the Himalayas, which add orographic lift and further increase precipitation.
