The British Isles

Homework!

Your turn!

Write a description about precipitation on the British Isles (minimum 50 words)

Use the following words:

evaporates / prevailing wind / southwestern wind / mountains / condensation / wet / rain shadow

Homework!

Your turn!

Water in the ocean evaporates, due to the heat of the sun. The prevailing wind on the British Isles comes from the southwest. We call this a southwestern wind. The wind blows the moist air against the mountains. When the moist air climbs, it cools down and there will be condensation. This will lead to wet weather on the southwest side of the mountains. The northeastern part of the mountain will stay dry, we call this the rain shadow.

Climate factors

#1 Latitude

Rule #1: How further from the Equator, how colder

(or: the higher the latitude, the colder)

#1 Latitude

#2 Altitude

Rule #2:  how higher, how colder

#2 Altitude

Sunlight doesn’t provide warmth right away (otherwise it would be really warm out in space!)

When the sunlight hits the earth, it’s reflected as warmth

From there the warm air rises and slowly cools

So the higher you go, the colder it gets!

#2 Altitude

Sunlight doesn’t provide warmth right away (otherwise it would be really warm out in space!)

When the sunlight hits the earth, it’s reflected as warmth

From there the warm air rises and slowly cools

So the higher you go, the colder it gets!

#3 Ocean currents

Rule #3: How further away from warm ocean currents, how colder (its winter)

#4 Distance from the coast 

Rule #4: The closer to the coast, the smaller the difference between summer and winter temperature.

The summer temperature is cooled by the sea

The winter temperature is warmed by the sea

#5 Prevailing wind direction

Rule #5: Dependent on its direction, wind can carry either warm or cold air and can either carry dry or moist air

Summarised

The following factors influence a place’s climate

(temperature and precipitation that is):

1. Latitude (distance from the Equator)
   
2. Altitude (height)
   
3. Ocean currents
   
4. Distance from the coast
   
5. Prevailing wind direction
   

5 main climate regions

1. Equatorial climates​ (or tropical climates)​
2.  Arid climates​ (or dry climates)​
3.  Maritime climates​ (or sea climates)​
4.  Continental climates​ (or land climates)​
5.  Polar climates​ (incl. mountain climates)​
