causes of tropical storms

Question 1

what things are needed for the formation of tropical storms?

Answer 1

• ocean depth of 60-70m
• sea temp above 27 degrees Celsius
• low wind shear
• not along the equator

Question 2

what happens when a storm makes landfall and why?

Answer 2

it dies out because it loses its energy source

Question 3

formation of a tropical storm:

Answer 3

• 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
