| Question | Answer |
|---|---|
| 2 assumptions of a ONE CELL MODEL | 1. a non rotating earth 2. a uniform body of water |
| 2 assumptions of a MULTI CELL MODEL | 1. a rotating earth 2. a uniform body of water |
| "ITCZ" what does it stand for? | Inter tropical convergence zone |
| Lifting mechanisms for the ITCZ | air rises from the top of the troposphere |
| Individual Cell name 3 | Hadley, Polar, Ferrel |
| Hadley cell | -subtrop high to equat. low - air rises at the equator - diverges aloft -cools and sinks |
| Polar cell- | -polar high to sub polar low -cold air at poles forms thermal high -air sinks and diverges |
| Ferrel Cell | -suptopical high to sub polar low -forms due to Hadley and polar cells |
| thermal direct VS. Thermal indirect | direct- warm air rises and cool air sinks indirect- cool air rises and warm air sinks |
| 3 main jetstreams | 1.Polar 2. subtropical 3.equatorial |
| subtropical mechanisms | 1. zonal flow 2. meridional flow |
