Explanation:
The peninsular part of India experiences peak summers earlier than northern India due to the northward movement of the sun, which causes the global heat belt to shift northward. The following points explain this phenomenon in detail:
1. Northward movement of the sun:
- The Earth's axis is tilted, causing the sun's rays to fall more directly on different parts of the globe at different times of the year.
- As the Earth moves around the sun, the angle at which the sun's rays fall on a particular region changes.
- During the summer solstice, which occurs around June 21st, the sun's rays fall directly on the Tropic of Cancer, which is located at approximately 23.5 degrees north of the equator.
- After the summer solstice, the sun's rays start moving southward.
2. Global heat belt:
- The region between the Tropic of Cancer and the Tropic of Capricorn receives the most direct sunlight and experiences the highest temperatures.
- This region is known as the global heat belt or the tropical zone.
- As the sun's rays move northward during the summer season, the global heat belt also moves northward.
3. Impact on India:
- The peninsular part of India is located closer to the equator and lies within the global heat belt.
- Therefore, as the sun's rays move northward, the peninsular region comes under the influence of the global heat belt earlier than the northern parts of India.
- This leads to the peninsular region experiencing peak summers earlier than the northern plains.
4. Other factors:
- While the northward movement of the sun is the primary reason for the early onset of peak summers in the peninsular region, other factors like less rainfall and the absence of cloud formation during that time may also contribute to the higher temperatures.
In conclusion, the peninsular part of India experiences peak summers earlier than northern India due to the northward movement of the sun, which causes the global heat belt to shift northward. This phenomenon leads to the peninsular region coming under the influence of the global heat belt earlier, resulting in higher temperatures compared to the northern plains.
