Atmosphere and tropical storms

What does low pressure mean?

Rain

What does high pressure mean?

Sunshine

Why is the equator hotter?

The sun is more concentrated.

What causes high pressure?

Cold air sinking with warm air evaporating.

What causes low pressure?

Hot air rises, cools and condenses into clouds.

What latitude and climate is the UK?

60 N, temperate rainforest

What conditions are needed for a tropical storm?

Warm oceans above 27 degrees, a cluster of thunderstorms, light cross winds and the spin of the earth.

Describe how tropical storms form.

Warm air and low pressure combine and warm air rises, as it cools and condenses clouds form which release latent heat energy which adds power to the storm. More warm air rises and due to the earth’s rotation it starts to move in a spiral. The air rises faster and cooler air is sucked downwards and wind spread increases. As the air rises, more air rushes to replace it. The tropical storm moves over the ocean picking up warm, moist are to fuel itself.

How do tropical storms end? (land)

If they lose their power source (Water over 27 degrees) and when friction slows the storm.

How do tropical storms end? (latitudes)

At higher latitudes it loses it’s power source (Water over 27 degrees)
