Explanation

The monsoon type of climate in India is influenced by several interconnected factors. Location is fundamental, as India's tropical belt position and latitudinal extent determine the initial climatic character. Thermal contrast, specifically the differential heating and cooling of the vast Asian landmass compared to the Indian Ocean, creates the pressure gradients necessary for seasonal wind reversal [4]. Upper air circulation, including the movement of westerly and easterly jet streams and the role of the Tibetan Plateau as a high-level heat source, significantly impacts the monsoon's onset and intensity [3]. Finally, the Himalayan Mountains act as a critical physical barrier, blocking cold northern air and forcing moisture-laden monsoon winds to rise and cause precipitation across the subcontinent [2]. Together, these factors create the unique monsoonal rhythm observed in India.
