Q

The Coriolis effect

A

Eastward rotation of wary on its axis deflects the moving air or water (or any moving object that has mass) away from its initial course

Q

Ferrel cells

A

Mid latitude circulations cells of each hemisphere

16
Q

Horse latitudes

A

High atmospheric pressure and little surface wind.
Ocean salinity is higher
Intersection of Hadley and ferrel cells at 30 degrees

17
Q

Trade winds

A

surface winds of Hadley cells as they move from the horse latitudes to doldrums

18
Q

Monsoons

A

Pattern of wind circulation. Wet summers dry winters. follow ITCZ south in the northern winter

19
Q

Air mass

A

Large body of air with nearly uniform temperature, humidity, and density. Density differences prevent air masses from mixing. Boundary of different air masses is a front

20
Q

Extratropical Cyclones

A

Form at boundary between each hemispheres polar cells and its ferrel cell (polar front)

21
Q

Tropical cyclones

A

Great masses of warm, humid, rotating air
