Paper 1 Section 3 Flashcards
- The UK has a temperate climate – What does this mean?
No extremes of temperature or precipitation (rainfall) Moderate / cool / mild. (compared to extreme climates like hot deserts or polar regions)
- What would a typical summer temperature be in the UK - 8°C 18°C or 28°C?
18 °C
- What is an air mass?
A massive amount (section)of air with a similar temperature and air pressure at the base.
- From which direction does the prevailing wind come from to reach the UK?
SW – blows over the Atlantic Ocean
- What are the characteristics of the tropical maritime air mass?.
Tropical = hot and maritime = moist because it has travelled over the sea picking up moisture as water vapour.
- Correctly label the 5 main air masses on the map of the UK below
Arctic maritime ,polar maritime, polar continental, tropical maritime, tropical continental
- How does the North Atlantic drift affect the UK’s weather?
NAD is a warm water current from the Caribbean. It brings warmer water to our shores and prevents the m from getting extremely cold in the winter time. The west coast of the UK rarely has frost / snow.
- How does continentality affect the UK’s weather?
The UK is surrounded by the sea which makes it’s climate milder. This is because the sea warms up slowly in the summer keeping the coast mild whereas it cools down slowly in the winter so the winters are cool rather than extremely cold. Places that are further from the sea e.g. Moscow are surrounded by land. This heats up quickly but also cools down quickly so summers are hot and winters are cold.
- Give an example of an extreme weather event caused by the tropical continental air mass.
Tropical = hot and continental = dry so an extreme weather event would be a heatwave and drought such as in July / Aug 2022 when temperatures exceeded 40*C in the UK
