Hurricanes KT

Question 1

True or False?
Tropical storms/ hurricanes are intense high pressure weather systems:

Answer 1

False

Question 2

When water vapour condenses in the atmosphere, latent heat is released. What effect does this have on the atmosphere?

Answer 2

Heats it up

Question 3

How does the release of latent heat affect evaporation rates/ energy of the storm?

Answer 3

Increases

Question 4

Does the coriolos force or trade winds cause the storm to rotate?

Answer 4

Coriolis force affects air travelling around the earth at different speeds depending on its location- deflects air to rotate anti-clockwise in the north h, clockwise in the south

Question 5

Why do sea temperatures need to be 27 degrees and above?

Answer 5

• For a hurricane to develop it needs heat from the ocean
• Heat= transferred from the ocean to the atmosphere when water at the ocean’s surface evaporates-> water vapour
• Causes ocean to cool slightly= heat is transferred to the atmosphere

Question 6

What direction do hurricanes move in the northern hemisphere?

Answer 6

West

Question 7

What direction do hurricanes rotate in the northern hemsiphere?

Answer 7

Anti-clockwise

Question 8

What pressure approximately is common in the eye of the hurricane?

Answer 8

950mb

Question 9

Why are there strong winds associated with the eye wall?

Answer 9

Strong horizontal winds move from high pressure to low pressure, converge on the eye

Question 10

What is the name of the scale used for hurricane classification?

Answer 10

Saffir-Simpson scale

Question 11

How many categories are there of hurricanes?

Answer 11

5

Question 12

How is the regularity and frequency of hurricanes changing?

Answer 12

Frequency= same
Regularity= stronger, lasting longer

Question 13

How are storm events predicted?

Answer 13

1. Satellite and radar technology= track the approach of the tropical storm
2. Reinforced aircraft= fly through and over tropical storms- weather radar can locate storms within 200 miles of the radar station
3. Computer forecast models= compare info on past storms+ info on atmospheric pressure, wind+ moisture
4. Computer models= measure low pressure, relief of land and wind speed to calc how much water will be pushed towards the shore by the force of the winds.

Provided peacekeeping force (teargas/loot trucks)

Question 20

How did the physical geog of Haiti affect the effects of the storm?
