Conditions Needed For Tropical Storm

Question 1

Name 6 conditions needed

Answer 1

Ocean temp 27 degrees 
Ocean temp 70m+
5-20 degrees north/ south of equator
Low level air convergence
Atmospheric instability
Latent heat / moisture supply

Question 2

Ocean temp 27 degrees

Answer 2

Provides continuous source of heat and moisture in order to maintain rising air currents.

Question 3

Ocean depth 70m

Answer 3

This moisture provides latent heat, rising air causes moisture to be released by condensation which drives system

Question 4

5-20 degrees north / south of equator

Answer 4

In order for the Coriolis Effect to bring about maximum rotation of air.

Coriolis effect is weak at equator and will stop circulation air flow from developing

Question 5

Low level convergence air

Answer 5

Winds have to come together near the centre of the Low pressure system it contributes to rotation.

Question 6

Atmospheric instability

Answer 6

Rapid outflow of air in upper atmospheric circulation pushed away warm air which has risen close to centre of storm

Question 7

Latent heat / moisture supply

Answer 7

TRS exists when there is a supply of latent heat / moisture it provides energy and low frictional drag on ocean surface to gain more speed

Hits land it slows
