The correct option is 2 only
Explanation
The Hot Weather Season in India (March to May) is driven by the apparent northward movement of the Sun toward the Tropic of Cancer. This results in a progressive northward shift of the global heat belt, influencing temperature distribution across the subcontinent.
Statement-wise Analysis:
- Statement 1 is Incorrect: In March, the heat belt is located over the central part of Peninsular India. Consequently, the highest day temperatures, reaching approximately 38°C, are recorded in the Deccan Plateau.
- Statement 2 is Correct: In May, the heat belt shifts further northwards, not southwards. During this time, the northwestern parts of India experience rising temperatures, often ranging between 45°C and 48°C. Temperatures do not drop below 30°C; rather, this region becomes the center of low pressure due to intense heating.
- Statement 3 is Incorrect: The hot weather season in South India is mild compared to North India. Despite the tropical location, the moderating influence of the surrounding oceans and the peninsular shape prevents temperatures from rising as sharply as they do in the continental interior of North India. Temperatures in the south typically range between 26°C and 32°C.
Key Takeaway: The Indian summer is characterized by the northward migration of peak temperatures from the Deccan (March) to Northwest India (May), with South India remaining relatively moderate due to maritime influence.
