Air Pressure And Wind Flashcards
Variation in air pressure from place to place are the principal cause of
Wind
The Coriolis effect influence
Wind direction
What is the ultimate energy source for most wind
Solar radiation
the force exerted by the weight of the air above is called
Air pressure
In the a hemisphere winds associated with l pressure system blow in which direction
Clockwise toward center
What are the forces that influence wind
Coriolis effect, pressure, gradient friction
A sea breeze usual originates during the
Day and flow toward land
Wind are labeled according to which of the following
The direction from which they blew
a wind that consistently blow more often from 1 direction that from any other is called a
Prevailing winds
Slandered sea level pressure in millibars is
1013.2 mb
High altitude high velocity rivers of air called
Jet stream
If earth did not rotate how would air at the equator move
Air would rise and move upward
Which surface winds blow between the subtropical high and the equator
Trade wind
In the northern hemisphere winds associated with a high pressure system blow in which direction
Clockwise outward
Which instrument is used to measure wind speed
Cup
In the northern hemisphere winds associated with a low pressure system blow in which direction
Conterclockwise center
Seasonal changes in wind direction associated with late land masses and adjacent to waterbodies
Moonsoons
Near the equator rising air is associated with a pressure zone known as
Equatorial low
Fair weather can usually be expected with the approach if which of the following
Anticyclone
Valley and mountain breeze are examples
Local winds
Which force generates winds
Pressure difference
Center of low pressure
Cyclone
What is the sea saw pattern if atmospheric pressure between eastern and western pacific
Southern oscillation
high pressure system are usually associated with which of the following
Descending air
Clear wether
Dry conditions
