Consider the following statements regarding global monsoon mechanisms that influence the rainfall pattern of Northeast India including Arunachal Pradesh: 1. The differential heating of the Asian landmass and the Indian Ocean creates a massive seasonal pressure gradient. 2. The northward shift of the Intertropical Convergence Zone (ITCZ) in summer draws moisture-laden winds across the equator. Which of the statements given above is/are correct?

💡 Solution & Explanation

Both statements are correct. The South Asian summer monsoon is driven by the intense heating of the Tibetan Plateau and continental Asia, creating a low-pressure trough that interacts with the northward migration of the ITCZ, pulling southwest winds laden with moisture across the Indian Ocean towards the Himalayas. This vast atmospheric circulation system is responsible for the intense seasonal rainfall experienced across Arunachal Pradesh. Understanding macro-meteorological forcing is critical for competitive geographical assessments.
