- Atmospheric circulation
- three types of air cells
- Hadley cell
- cold, high altitude air sinks (rain)
- Ferrell cell
- polar air and subtropical air mixes and the subtropical air rises
- polar cell
- cold dense air sinks (rain)
- Hadley cell
- air it hotter at the equator
- the suns radiation is more concentrated at the equator because it is hitting a smaller area.
- it is cooler at the 60 degree latitude
- the sun is heating up a larger area so the heat is more spread out, this means it is cooler there.
- order of events
- 1. hot air rises from the equator
- 2. as the hot air rises, it cools, condenses and sinks and this is known as the Hadley cell.
- 3. some of the polar air continues to rise and mixes with the subtropical air, this is known as the Ferrell cell.
- 4. The subtropical air continues to rise before cooling, condensing and sinking. This is know as the polar cell.
- three types of air cells
