Match the local weather phenomena occurring during the pre-monsoon season in India with their corresponding states/regions: List-I (Phenomena) List-II (Regions) a. Mango Showers 1. West Bengal b. Kal Baisakhi 2. Kerala and Karnataka c. Loo 3. Northern Plains of India d. Bardoli Chheerha 4. Assam Choose the most appropriate answer from the options given below:

The correct answer is a-2, b-1, c-3, d-4 . Key Points Mango Showers (Kerala and Karnataka) : These are pre-monsoon showers common towards the end of the summer season in Kerala and coastal Karnataka . Locally, they are known as Mango Showers because they help in the early ripening of mangoes . Hence, pair a is correctly matched with 2. Kal Baisakhi (West Bengal) : These are localized thunderstorms associated with violent winds and torrential downpours, often accompanied by hail. In West Bengal , these storms are known as Kal Baisakhi , which means the calamity of the month of Baisakh ( April ). They are very useful for tea , jute , and rice cultivation. Hence, pair b is correctly matched with 1. Loo (Northern Plains of India) : The Loo is a strong, gusty, hot, and dry summer wind that blows during the afternoon over the Northern and Northwestern parts of India , including states like Punjab , Haryana , Rajasthan , and Uttar Pradesh . Direct exposure to these winds can even prove fatal as they cause severe heatstroke. Hence, pair c is correctly matched with 3. Bardoli Chheerha (Assam) : In Assam , pre-monsoon thunderstorms are locally known as Bardoli Chheerha or Bordoisila . These storms are essential for the tea plantations in the region and occur primarily during the months of April and May . Hence, pair d is correctly matched with 4. Additional Information Pre-Monsoon Season : Also known as the Hot Weather Season , it lasts from March to May in India . During this period, the global heat belt shifts northward due to the apparent northward movement of the sun. Atmospheric Pressure : In the summer months, India experiences rising temperatures and falling air pressure in the northern part of the country. Towards the end of May , an elongated low-pressure area develops in the region extending from the Thar Desert in the northwest to Patna and Chotanagpur plateau in the east and southeast. Cherry Blossoms : In Karnataka , pre-monsoon rainfall is also referred to as Cherry Blossoms or Coffee Showers . This is because this rain is extremely beneficial for coffee flowers to blossom at the right time. Blossom Showers : Similar to Mango Showers , this term is frequently used in Kerala to describe the rainfall that occurs before the regular monsoon hits the coast, aiding various plantation crops. Important Points Impact on Agriculture : While Loo is generally considered harmful to human health and crops due to its desiccating nature, other pre-monsoon winds like Kal Baisakhi and Bardoli Chheerha are vital for specific agricultural outputs like Jute and Tea . Norwesters : Kal Baisakhi is also known as Norwesters because these storms usually originate in the Chotanagpur Plateau and move towards the east ( Northwest direction relative to the coast). Nature of Precipitation : These pre-monsoon phenomena are characterized by convectional rainfall . The intense heating of the land leads to the rising of air, which cools and condenses to form cumulonimbus clouds, resulting in sudden, heavy showers. Regional Variations : In South India , the proximity to the sea moderates the temperatures compared to the Northern Plains , but the moisture influx leads to higher humidity and specific local storm patterns.
