Disastrous Weather


What are cyclones

Cyclones are speeding winds that are hundreds of miles long. In the north, they spin in a counterclockwise direction and in the south, they spin in a clockwise direction. This type of weather causes devastating destruction to happen in their way.

Where They are Found

The term, cyclone, is the same as hurricanes, typhoons... The only difference is that they are called cyclones if they are formed in the Indian ocean.

Cyclones form when warm air rises over the ocean and gets replaced by cooler air. This cool air eventually get warmer and gets replaced by even more cool air. This cycle keeps repeating and it start getting spiral motion and turns into a cyclone.


  • Cyclones can happen on Mars and Neptune
  • Cyclones can be up to 2000 km across
  • The fastest wind speed in a cyclone is 408 kph
  • The eye, or the center, of a cyclone is the part that is calmest

Types of Cyclones

Tropical Cyclone

Tropical cyclones have low air pressure and thunderstorms all around it. These cyclones also cause flooding. They are formed around the tropical area. They fuel on warm air that rises from the eye, which makes them hot core cyclones. They could turn into extratropical cyclones if they get more latitude.

Extratropical Cyclone

Unlike tropical cyclones, extratropical cyclones are far from the equator and have fronts in them.

Polar Low Cyclone

Polar low cyclones are low pressured cold core cyclones. They are found in the southern and northern hemispheres. These cyclones have short lives.

Subtropical Cyclone

Subtropical cyclones have both tropical and extratropical features. People didn't know if to make it tropical or extratropical, so scientists finally named it subtropical.
