horizontal movement of air parallel to Earth's surface
instrument used to measure wind speed
easterly moving air at the top of the troposphere; convection cells
lowest zone of the atmosphere where people live
difference in air pressure for a specific distance
air pressure gradient
jet streams
anemometer
wind
troposphere
extreme weather changes caused by the shifting wind and pressure belts in parts of Asia and India; seasonal very high rain and winds
wind from the direction that is most common at a particular place or season.
high wind speeds
cause of spinning directions of winds; counterclockwise in southern hemisphere and clockwise in northern hemisphere
series of zones where winds move primarily in a specific direction over time; in the Northern Hemisphere to the right
low wind speeds
prevailing winds
Coriolis effect
steep pressure gradient; close isobars
far apart isobars
monsoons
planetary wind belts
in the northern hemisphere lows spin
in the northern hemisphere highs spin
where two air masses of different characteristics meet
high pressure with wind blowing away from the center
low pressure with wind blowing toward the center
large body of air in the troposphere with similar characteristics of pressure, moisture and temperature
air mass
counterclockwise toward center
cyclone
anticyclone
clockwise away from center
front
boundary of opposing wedges of cold air masses that lift a warm air mass causing mid latitude cyclones
boundary of an advancing cold air mass and a warmer air mass
ever-changing boundary between the cold air masses of the poles and the warmer air masses of the equator
boundary of an advancing warm air mass and a retreating cold air mass
when two adjacent air masses stay in the same place
stationary fronts
cold front
polar front
warm front
occluded front
