Q

formation of a tropical storm:

A
  • suns solar radiation warms oceans to 27 degrees Celsius
  • this causes moist air to rise, giving low pressure at the centre of the storm
  • this air cools as it rises, causing condensation, clouds to form, rainfall
  • some cooled air sinks, creating the eye
  • air rushes in from high pressure areas outside the storm to low pressure areas inside the storm, creating winds
  • the whole storm rotates due to the earth’s spin
