Frequently Asked Questions

What is a cyclone?

A cyclone is a large-scale air mass that rotates around a strong center of low atmospheric pressure, typically bringing strong winds and heavy rain.

How do cyclones form?

Cyclones form over warm ocean waters, where warm, moist air rises and creates a low-pressure system. This system draws in more warm air, which fuels the storm's rotation and intensifies it.

What is the difference between a cyclone and a hurricane?

Cyclones, hurricanes, and typhoons are essentially the same weather phenomenon, but they are named differently based on where they occur. Cyclones form in the Indian Ocean and South Pacific, hurricanes in the Atlantic and Northeast Pacific, and typhoons in the Northwest Pacific.

How does ocean warming affect cyclones?

Ocean warming can increase the intensity and frequency of cyclones, as warmer water provides more energy for these storms to form and strengthen.

What are some recent examples of cyclones in the Indian Ocean?

Recent examples include Cyclone Nisarga and Cyclone Tauktae, which affected the Arabian Sea and the coast of Maharashtra in India.
