Q

How do tropical storms form?

A
  • A strong upward movement of air draws water vapour up from the warm ocean surface (27 degrees +)
  • This evaporated air cool as it rises and forms thunderstorm clouds
  • Condensing air releases energy which powers the storm and draws up even more water
  • Several small thunderstorms combine to form a giant spinning storm
  • Storm develops an eye where air rapidly descends
  • Upon landfall, storm loses energy and it slows and weakens

Q

How are storm surges formed?

A

When the storm blows the ocean surface and creates vertical circulation in the water, which gains height in shallower water

Q

what are strong winds formed by storms?

A

When pressure changes rapidly over a small distance, and air flows from high-pressure to low pressure

16
Q

Which areas are at risk from strong winds?

A

Coastal regions, as the storm looses energy once it reaches land

17
Q

How are the strongest winds created?

A

By the biggest differences in pressure

18
Q

What are landslides?

A

Involves the movement of rock, earth or debris, can be caused by heavy rain

19
Q

Why can particular areas land slide?

A

When they have 2 separate layers, one of stable bed rock and another of loose, unconsolidated sediment

20
Q

What is a common form of disaster associated with tropical storms?

A

Heavy rainfall and flooding

21
Q

Where does the heaviest rain occur?

A

In the eyewall

22
Q

Why do floods occur?

A

Because the ground becomes saturated with the heavy rain and then water builds up and rivers burst their banks

23
Q

How can storms be predicted?

A

Future events can be predicted using ones in the past and the frequency of storms can also show patterns

24
Q

What can be used to gauge wind speeds, pressure and precipitation?

A

Aircraft and drones

25
Q

How can meteorologists help people to prepare?

A

By giving a picture of the flooding of weather systems a storm may cause and the area it may hit

26
Q

How can satellites be useful?

A

They track the storm and give a hemispheric view of it, as well as 3D images and sea surface temperatures

27
Q

What temperature must the sea surface be for a storm to form?

A

28 degrees

28
Q

What is a category 1 storm?

A

Very dangerous winds produce some damage, damage to trees and power lines as well as some homes

29
Q

What is a category 5 storm?

A

Catastrophic damage will occur, high percentage of homes destroyed, total roof failure and wall collapse, power outages

30
Q

What scale is used to categorise storms?

A

The Saffir-Simpson Scale

31
Q

What do wind speeds have to reach to be a category 5 storm?

A

157mph

32
Q

What is done by the US Air Force and National Oceanic and Atmospheric Administration?

A

They fly aircraft’s through storms to gauge wind speeds, barometric pressure, rainfall and snow as well as dropping sensors which fall through the storm and send back data

33
Q

Which is the most useful satellite for monitoring storms?

A

The TRMM satellite - Tropical Rainforest Monitoring Mission

34
Q

What has TRMM helped to discover?

A

Eyeball ‘hot towers’ through its CT scans if storms

35
Q

What are eyeball ‘hot towers’?

A

Rainclouds that reach the lowest layer of the atmosphere, bringing heat to high altitudes
