Nor Westers are dreaded evening thunderstorms seen in _________.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Bengal and Assam.
Nor'westers, or "Kalbaisakhi" (which means "storm in April"), are severe evening thunderstorms primarily affecting the eastern regions of India and Bangladesh, especially West Bengal, Assam, and northern Bihar. Occurring most frequently from March to May, during the pre-monsoon period, these storms are known for their abrupt, intense gusts of wind, heavy rainfall, and occasional hail.
These storms arise due to the climatic shift from the cooler, dry winter weather to the hotter, humid summer conditions. The meeting of warm air from the Bay of Bengal with cooler air from the north creates unstable atmospheric conditions, fueling the development of these thunderstorms.
