Q

How do tropical storms form?

A
  1. sun’s solar radiation warms oceans in tropics
  2. warms to 27C
  3. warm moist air rises through thermals creating low pressure at centre of storm
  4. air cools as it rises causing condensation
  5. some cooled air sinks to create the eye
  6. air rushes in from higher pressure areas to lower pressure areas which creates storm winds
  7. storm rotates due to earth’s spin
