Study Notes
- Narvik in Norway is located above the Arctic Circle, while Goose Bay in Canada is at the same latitude as Amsterdam.
- Narvik's harbor does not freeze in winter, but Goose Bay's does.
Sea Currents
- Wind often blows from the same direction in many places.
- In the Netherlands, there's often a southwest wind.
- Wind blowing over the sea drags seawater along, creating sea currents.
- Sea currents largely follow the same pattern as air currents, forming part of the oceanic circulation.
Warm and Cold Currents
- A warm sea current originates from a relatively warm area.
- The Gulf Stream flows from the Caribbean to Northwest Europe.
- The Gulf Stream provides warmth and ice-free harbors as far as Murmansk.
- The East Australian current brings warmth from the Great Ocean to New Zealand.
- A cold sea current comes from a relatively cold region.
- Warm currents flow from the equator towards the poles.
- Cold currents flow from the poles towards the equator.
- The Labrador Current flows from Baffin Bay along the Canadian coast, causing a cold climate and frozen harbors down to Newfoundland.
- The Kuril Current contributes to cold winters on the Japanese island of Hokkaido.
- Many deserts are found at coasts with cold sea currents in the subtropics. This is the case in Mauritania with the Canary Current and Baja California with the California Current.
- Cold seawater cools the air above it, reducing its moisture capacity.
- As this cold air flows onto land, it warms up but cannot absorb more moisture due to being over land, resulting in dry conditions and no rainfall.
Climate Zones
- Atmospheric circulation largely determines global climate patterns.
- Areas with the same climate are called climate zones.
- Tropical climates are found around the equator, while dry climates are around 30° N.B. and Z.B.
- Temperate climates are found at sea and inland at approximately 60° N.B. and Z.B.
- Polar climates are found around the poles
Factors influencing climat
- There are three factors that influence climates: geographic latitude, mountains and elevation, and type of surface.
Geographic Latitude
- The distribution of heat on Earth is greatly influenced by air and sea currents.
- The Tropics receive an excess of solar heat because the sun is high in the sky.
- Without air and sea currents, the tropics would be even warmer, and higher latitudes would be colder.
- Air and sea currents together transport heat towards higher latitudes.
- This results in a more even distribution of warmth across the Earth.
Mountains influence
- Mountains obstruct wind from the sea, creating dry regions inland
- Wind direction is a factor for climat
- The wind, air rises and cools down and results in stowing rain
- Air descends en warms up
- Dryness
- Shadow of rain
Terrain
- Coastal areas tend to be rainier with milder winters and cooler summers due to winds coming off the sea.
- The oceans retain heat longer and warm up more slowly than land which results in rain.
