Monsoon Climate and Its Effects

The video explains the monsoon phenomenon, focusing on South Asia. Monsoons are seasonal wind reversals that bring dramatic weather changes, particularly heavy rains. The term 'monsoon' originates from the Arabic word 'mawsim', meaning season. The video details how land heats faster than water, creating low pressure over the Indian subcontinent, drawing in moist air from the Indian Ocean. This results in the southwest monsoon, which brings significant rainfall to India, especially in the northeast. The monsoon is crucial for agriculture but can cause severe flooding. As the season ends, winds reverse, marking the return to the dry season.
