GLOBAL WINDS

Grade review of global wind patterns

AB
TRADE WINDSresponsible for pushing hurricanes across the atlantic
WINDmovement of air
GLOBAL WINDSpolar easterlies, trade winds, prevailing westerlies, doldrums, horse latitudes
CORIOLIS EFFECTcurving of global winds due to earth's rotation
JET STREAMa stream of air in the upper troposphere
SEA BREEZEcool air over the ocean blows towards the land
DOLDRUMSlow pressure zone near equator where the air is very calm
HORSE LATITUDEShigh pressure zones at 30 degrees latitude where the air is very calm
TRADE WINDSwinds blow east to west between equator and 30 degrees latitude
PREVAILING WESTERLIESblow from west to east between 30 degrees and 60 degrees
POLAR EASTERLIESblow from east from poles
CONVECTION CELLSvery large circular patterns of air responsible for the global wind pattenrs
PRESSURE BELTSareas of pressure that separate convection cells
LOW PRESSUREformed by rising warm air
HIGH PRESSUREformed by sinking cool air
LAND BREEZEcool air over the land blows toward the sea
NORTH SIDEwhere the wind is the strongest in a hurricane
UNEVEN HEATING OF EARTHdifferences in air pressure is caused by this
0 DEGREESequator

90 DEGREES SSouth Pole
SOLAR ENERGYthe equator receives more of this
FROMwinds are named for the direction that winds blow ----
RISESwarm air does this
SINKScool air does this
DENSEthe molecules in cool air are closer together, they are -----
LESS DENSEthe molecules of warm air are farther apart, the are ---- ------
HURRICANE HUNTERSvolunteers who fly into hurricanes to gather information
HIGH PRESSURE AREAScreated at the poles and flow toward the equator
LOW PRESSURE AREAcreated at the equator, as warm air rises
