Key term
On what two properties are air masses classified?
Key term
Name the five air masses that affect the UK.
Questions from this subtopic
Each one with the model answer underneath.
- 1
Define an air mass.
Model answer
An air mass is a large body of air with broadly uniform temperature and humidity. The properties are acquired from the source region where the air stagnated.
- 2
On what two properties are air masses classified?
Model answer
Air masses are classified on the temperature of the source region and on whether that source is land or sea. The pairs give tropical or polar and continental or maritime.
- 3
Name the five air masses that affect the UK.
Model answer
The five are tropical maritime, tropical continental, polar maritime, polar continental and Arctic maritime.
- 4
Describe the source region and characteristics of tropical maritime air.
Model answer
Tropical maritime air comes from the Azores and the subtropical Atlantic. The air is warm and very moist, bringing mild cloudy weather with drizzle.
- 5
Describe the source region and characteristics of tropical continental air.
Model answer
Tropical continental air comes from North Africa and southern Europe. The air is hot and dry and brings heatwaves in summer.
- 6
Describe the source region and characteristics of polar maritime air.
Model answer
Polar maritime air comes from northern Canada and Greenland across the Atlantic. The air arrives cool, moist and unstable with showers and bright intervals.
