How are they made?

A

  • More warm air rises and due to the Earth’s rotation, starts to move in a spiral. It cools and condenses and from clouds → releasing lots of energy
  • The air starts to rise faster and cooler air is sucked downwards. Wind speed starts to increase
  • The storm moves over the ocean, picking up warm, moist air. Wind reaches more than 120 km/has cold air is drawn into the eye
  • Storms track westwards until they reach land and lose energy
