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