Explanations:Cyclones are intense low-pressure systems that form over warm ocean waters and can cause significant damage when they make landfall. They are categorized based on their wind speeds and the potential for destruction they can cause. Cyclones are particularly common in the Bay of Bengal and the Arabian Sea, affecting the coastal regions of India.
One of the most significant cyclones to hit the Indian subcontinent in recent years was Cyclone Amphan, which made landfall in May 2020. This cyclone was particularly destructive, affecting the states of West Bengal and Odisha, with Kolkata being one of the most severely impacted areas. The cyclone caused widespread damage to infrastructure, including power outages, flooding, and destruction of homes and buildings. It was one of the strongest cyclones to hit the region in decades, with wind speeds reaching up to 250 km/h.

Other cyclones that have affected India in recent years include Cyclone Nisarga, which hit the western coast of India in June 2020, and Cyclone Fani, which hit the eastern coast in April 2019. However, these cyclones did not affect Kolkata. Cyclone Vayu, which hit the western coast of India in June 2019, also did not impact Kolkata.
