1.4 Tropical Cyclones

Question 1

Names in Different parts of the World

Answer 1

N + S America = Hurricanes
Africa + India = Cuclones
Russia + NE Asia - Typhoons
Australia = Willy Willies

Question 2

Source Areas

Answer 2

Occur a few degress N + S of the equator (in the tropics). Coriolis effect adds to rotation. Likely to occurin ITCZ (area of permament low pressure generated by global circualtion within the Hadley cells)

Question 3

How they form

Answer 3

If the water that fuels the cyclone is hotter, the intensity of it increases. Dissipitation happens in the cyclone when it reaches an area of land, or cold water, because it doesn’t have warm water fueling it. Dissipitation also happens when another weather system blows wind in the opposite direction

Question 4

Air pressure

Answer 4

Air pressure is important to cyclones because tropical cyclones have much lower air pressure than the air surrounding them. The bigger the difference in pressure, the steonger the winds

Question 5

Coriolis Force

Answer 5

A strong force created by the Earth’s rotation

Question 5

Eye

Answer 5

The centre of a tropical cyclone

Question 6

Seasonal Distribution

Answer 6

How something such as tropical cyclones occur at different times of the year

Question 7

Source Area

Answer 7

The region in which a tropical storm first forms

Question 8

Track

Answer 8

The path followed by a tropical storm
