what is the earth’s tilt

thermal

a rising current of relatively warm air

thermally direct cell

it is driven by energy from the sun as warm air rises and cold air sinks.

coriolis force

An apparent force that as a result of the Earth’s rotation deflects moving objects to the right in the north/south hemisphere

ferrel cell

named after the american scientist, william ferrel

william ferrel

doldrums

a state or period of inactivity, stagnation, or slump

condensation nuclei
water vapor
lifting action

cloud formation

tropopause

acts like a barrier, causing the air to move laterally toward the poles

intertropical convergence zone

very wet area as the rising air develops into huge thunderstroms that drop big amounts of rain in the form of heavy showers

intertropical covnvergence zone

it is a belt of converging trade winds and rising air that encircles the earth near equator

horse latitude

these are located at about 30 degrees north and south of the equator

horse latitude

these are characterized by calm winds and little precipitation

jetstreams

swift flowing air currents thousands of kilometers, a few hundred kilometers wide, and only a few kilometers thick.”

100 knots/occasionally 200 knots

Wind speeds in the central core of a jet stream often exceed what speed

tropopause at elevations 10km and 20km

where are jetstreams found?
