Hurricane Ida’s, in USA, created deadly havoc in Pennsylvania, New Jersey and New York days after the system hit the Gulf Coast — some 1,000 miles away.

           Hurricanes, cyclones, and typhoons are all the same weather phenomena.

   It’s called  “hurricane” in the Atlantic and Northeast Pacific.

     typhoon”  in the Northwest Pacific 

“Cyclones” occur in the South Pacific and Indian Ocean.

Conditions for Hurricane Development

The ingredients for these storms include a pre-existing weather disturbance, warm tropical oceans, moisture, and relatively light winds. If the right conditions persist long enough, they can combine to produce the violent winds, waves, torrential rains, and floods.

 Ocean waters must be above 26 degrees Celsius

Distance from the equator; without the spin of the earth and the resulting Coriolis force, hurricanes would not form. Since the Coriolis force is at a maximum at the poles and a minimum at the equator, hurricanes can not form within 5 degrees latitude of the equator. The Coriolis force generates a counterclockwise spin to low pressure in the Northern Hemisphere and a clockwise spin in the Southern Hemisphere.

A large-scale closed circulation system in the atmosphere characterizes it. Combining low pressure and strong winds that rotate counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.
