1

What are the 4 air masses?

Tropical Continental
Tropical Maritime
Polar Continental
Polar Maritime

2

Explain temperature in Altitude

Every 100m we lose 1 degrees. This is known as Lapse Rate.
Air becomes less dense and is less able to hold heat

3

Explain Precipitation in Altitude

Air arriving from Atlantic Ocean is forced to rise over high land in Wales
This creates relief rainfall as it cools and condenses

4

Explain the four air masses?

North East - cold air travelling over cold land. Weather is dry
South East - brings warmer temp as it arrived from warm land
South West - arrives from warm tropical area over the sea brings high temp
North West - arrives from cold polar regions with wet cold weather

5

Explain continentality - Summer

The sea takes longer to warm up and it keeps coastal areas cool

6

Explain continentality- Winter

Sea insulates area near the coast. Because absorbs heat slowly but retains it so costal areas are milder in winter

7

Give five things that affect the weather?

Altitude
Air masses
Continentality
Aspect
Latitude

8

Explain continentality - Precipitation

As moist air arrives it begins to rise, cool and condenses over the land.

9

Explain Aspect

South Facing receive direct sunlight.
North Facing remain shaded as the sun moves throughout the day

10

Explain Latitude

Equator - The sun is over head and its rays are concentrated over a smaller surface area.
Further North or South the sun rays are spread over greater area so less concentrated
