"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
