lines connecting areas of equal pressure
isobars
lines connecting areas of equal temperature
isotherms
used to measure temperature
thermometer
used to measure air pressure
barometer
used to measure wind speed
anemometer
used to measure humidity
hygrometer
causes an apparent change in pitch
Doppler effect
causes wind to curve
Coriolis effect
winds between the poles at either 60 degrees North/South latitude
polar easterlies
winds between 30 & 60 degrees latitude
prevailing westerlies
winds between equator & 30 degrees North/South
trade winds
very high and fast winds
jet streams
boundary between two air masses
fronts
weak surface winds near 30 degrees North/South latitudes
horse latitudes
weak winds near the equator
Doldrums
cold dense air that displaces warm air
cold front
warm air that displaces cold air
warm front
two air masses meet, but neither advance
stationary front
cold air that moves rapidly and over takes warm front
occluded front
winds rotate counter-clockwise (losing time)
low-pressure systems
winds rotate clockwise (gaining time)
high-pressure systems
large volume of air
air mass
area air mass forms
source region
short term atmospheric variation
weather
long term variations in weather
climate
