What is the air mass in the UK?
An air mass is a large volume of air which travels from one area to another. The weather an air mass brings is determined by the region it has come from and the type of surface it has moved over. There are five main air masses which affect the UK as detailed by the map below….Air masses.

What 4 air masses affect the UK?
The four main air masses that affect the British Isles are:
- Tropical maritime (warm and moist air)
- Tropical continental (warm and dry air)
- Polar maritime (cold and moist air)
- Polar continental (cold and dry)
What are the 5 main air masses?
Five air masses affect the United States during the course of a typical year: continental polar, continental arctic, continental tropical, maritime polar, and maritime tropical.
What are the 4 air masses called?
There are four categories for air masses: arctic, tropical, polar and equatorial. Arctic air masses form in the Arctic region and are very cold. Tropical air masses form in low-latitude areas and are moderately warm.
What is an Arctic air mass?
Arctic air masses, designated by the letter ‘A’, are very cold as they originate over the Arctic or Antarctic regions. Polar air masses, designated by the letter ‘P’, are not as cold as Arctic air masses as they originate over the higher latitudes of both land and sea.
What are the major air masses?
In the United States the major air mass types are typically continental Polar, maritime Polar, continental Tropical, and maritime Tropical.
Which 2 air masses are dominant in the UK winter?
- Arctic Maritime – originating from the Arctic area, this air mass brings cold, snowy weather in winter, particularly to Northern Scotland.
- Polar Continental – cold, dry weather all year round.
- Polar Maritime – this air mass has travelled from the north over the sea, and hence brings cold, wet weather.
What are the 5 types of air?
From these categories come the five combinations of air mass types that influence our U.S. and North American weather.

What is continental air mass?
continental air mass, vast body of air that forms over the interior of a continent, excluding mountainous areas. See air mass.
What is an arctic air mass?
Which air mass brings dry weather to the UK?
Tropical Continental
4 Tropical Continental – travelling from the south and southern Europe over land, this air mass brings warm, dry weather. This air mass can cause heat waves in the UK in summer.
What are the air masses that affect the UK?
The UK is at the meeting point of several different types of weather from different directions. There are 5 main air masses that affect the UK. These are polar continental, arctic maritime, polar maritime, tropical maritime and tropical continental. Each brings unique weather to the UK.
What are the different types of air masses?
There are six main types of air masses that affect the British Isles. We classify these air masses primarily by the area in which they originate. They are classified as continental or maritime – dependent on whether they originate over land or sea – and arctic or antarctic, equatorial, tropical, or polar,…
How big are the air masses in the atmosphere?
Air masses. Air masses are large bodies of air that create distinctive weather conditions across the globe. An air mass is defined as a body or ‘mass’ of air with uniform weather conditions, such as similar temperature and humidity. Air masses may cover several million square kilometres and extend high up into the atmosphere.
When is the most common air mass in Africa?
This air mass originates over North Africa and the Sahara (a warm source region). It is most common during the summer months June, July and August, although it can occur at other times of the year.
