उत्तर
- A convectional type of rainfall is experienced in the equatorial region.
- Air near the equatorial region is heated more due to high-intensity solar radiation. It expands, becomes lighter and moves in the upward direction in the form of convectional currents. The rising air cools down. Relative humidity increases and condensation begins. Clouds are formed and every day in the evening, the equatorial regions get a convectional type of rainfall.
- India is not an equatorial country, and the topography of India is the main reason for orographic rainfall in India.
Therefore, convectional types of rainfall are not prominent in India.
