(a) Name two states that are affected by tropical cyclones on the eastern coast of India. (b) The temperate cyclones cause less damage than the tropical cyclones. Give any two points to support this statement. (ii) (a) Name the local wind that causes rainfall in the states of Assam and West Bengal in the month of April. (b) How is this rainfall beneficial for the states mentioned above?
Answer (1)
(a) Two states on the eastern coast of India that are frequently affected by tropical cyclones are Andhra Pradesh and Odisha. These states face cyclones that originate in the Bay of Bengal, especially during the pre-monsoon and post-monsoon seasons.
(b) There are two points to support the statement that temperate cyclones cause less damage than tropical cyclones:
Intensity: Tropical cyclones are generally more intense in terms of wind speed and rainfall compared to temperate cyclones. The energy and power of tropical cyclones can cause significant destruction to infrastructure, homes, and the natural environment.
Affected Areas: Tropical cyclones usually impact densely populated coastal regions, leading to greater potential for loss of life and property. In contrast, temperate cyclones often occur over landmasses and affect larger, less populated areas, which can help minimize damage.
(ii) (a) The local wind that causes rainfall in the states of Assam and West Bengal in April is called the 'Nor'wester'. These are violent thunderstorms that occur due to the heating of the land.
(b) The rainfall brought by Nor'westers is beneficial for Assam and West Bengal in several ways:
Agriculture: This pre-monsoon rainfall helps in preparing the soil and supports the cultivation of crops like rice, jute, and tea, which are important for the local economy.
Water Supply: The rainfall replenishes water resources, such as rivers and reservoirs, which are crucial for both agriculture and the daily water needs of the population.
