1.1 Global Circulation Cells Flashcards
On a graph what do the lines and bars represent?
Lines=Temperature
Bars=Precipitation
Where do winds blow from?
Winds blow from areas of high pressure to areas of low pressure, transferring heat away from Equator.
What are the 3 different global atmospheric circulation cells?
Hadley, Ferrel, Polar
What latitude to does cool air sink?
30° North or South
What weather would be found at low pressure?
Clouds and Rain
What happens at low pressure surfaces?
Air is heated and rises into atmosphere causing there to be less air at the surface. The air cools,condenses, forming rain/clouds.
What weather is caused by at high pressure surfaces?
Sun and Clear Skies
What happens at high pressure surfaces?
Air cools and becomes more dense and sinks. This transsfers heat to the ground resulting in clear skies.
Why does the Equator receive the most radiation from the Sun?
This is because the Sun’s rays are concentrated over a small area and strike at a right angle. It also has to travel through less atmosphere.
What is the Coriolis Effect?
When wind is deflected due to rotation of the Earth.
What do ocean currents do?
They transfer heat around the world and away from the Equator.
What are the High and Low pressure examples?
Tindouf/Algeria and Singapore.
What does ITCZ stand for?
Inter Tropical Convergence Zone
