The factors that affect the formation of a storm hazard

Question 1

The factors that affect the formation of a storm hazard

Answer 1

• Ocean
• High sea surface temperature
• Atmosphere instability
• Rotation of the earth
• Uniform wind direction at all levels

Question 2

Ocean

Answer 2

• Tropical storms derive their moisture (evaporation)
• Energy (latent heat) from oceans
• Clear links with the water cycle

Question 3

High sea surface temperatures

Answer 3

• Sea-surface temp more than 26 = tropical storm

- Formed in low lats during summer - temps are at highest

Question 4

Atmospheric instability

Answer 4

• TS - most likely to form in regions of intense atmospheric instability - warm air forced ain air
• ITCZ - 2 limbs of the Hadley cell converge = low pressure on the ground = perfect for TS.

Question 5

Rotation of the earth

Answer 5

• Certain amount of spin is needed = TS

- Coriolis effect = increases the further away from equator

Question 6

Uniform wind direction at all levels

Answer 6

• Winds from different directions at altitude prevent a tropical storm from attaining height and intensity

Question 7

Thermal equator

Answer 7

• Moves with the seasons

Question 8

ITCZ

Answer 8

• Belt of low pressure which circles the earth generally around the equator

Question 9

Coriolis force

Answer 9

• Moving air deflected to the right in the northern hemisphere
• Left in the southern hemisphere
