movement in the atmosphere

isobars

lines of equal pressure the tighter the isobar are on the map the stronger the wind

what are the main cause of wind

differences in temperature and pressure

winds are named after what

the direction that they come from

coriolis effect

bending or curving of wind it is caused by the rotation of the earth

friction

the slowing of the wind as it moves along earth's surface

winds over the ocean are generally …

faster than the surface

upper level winds are generally …

faster than surface winds

air pressure

the weight of the atmosphere as its pushed down upon earth surface

pressure gradient

the change of pressure over a horizontal distance

global winds

caused by the uneven heating of the earth

where does solar radiation hit more directly

equator for differential heating

heat moves from the …

equator to the poles

convection currents

hot air rises and cools

whats a major wind in the 60

polar easterlies

whats a major wind in the 30

weaterlies

whats a major wind by the equator

northeast trade winds

santa ana winds

winds that blow around high pressure in the southwestern US toward the Pacific ocean is generally warm and dry

land breeze and sea breeze

wind that occurs a long the coastal regions created by different temperatures

during that day land …

warm faster than the water so the air rises and cools air above the ocean replace it

during the night …

land cools faster than the water and air over the ocean rises and cools and land air rushes to replace it

land breasts accrues when

during the day

sea breeze occure when

during the night

warm and unstable air

rises

cool stable air

sinks

earth surface is heated from the sun making air

rise during the day and becomee unsable

when the sun is gone the air

becomes stable and sinks

what happens when air rises and cool to its dew point

clouds form

if warm air rapidly cools to its dew point what occures

rain and thunderstorms

virga

rain the falls form a cloud but never reaches the surface because of evaporation
