What do temperature inversions do to air pollution?
Temperature inversions traps air pollution.
100
During El Nino what happens to air temperatures along south american side of the pacific ocean?
The air temperature gets warmer.
100
What is wind the result of?
Horizontal differences in air pressure.
100
At which latitude lines would deserts be located?
30 degrees N & 30 degrees S
100
What is a prevailing wind?
A wind that blows more often in one direction than any other.
200
When would temperature inversions develop close to the ground?
When the ground is a better radiator of heat than the air above it.
200
During El Nino, what will happen to the ocean temperature off the coast of south america?
The water will become warmer.
200
How is wind measured?
A Barometer
200
At which latitude lines would rain forests be located?
The Equator
200
What is the prevailing wind in the United States?
The Westerlies
300
With temperature inversions, why are mixing depths usually greater during the afternoon hours?
Relative Humidity
300
During El Nino what happens to the storms and precipitation that normally occur in the western part of the pacific ocean?
Storms and precipitation become more extreme and come around more often.
300
What is the ultimate energy source for most wind?
Solar Radiation
300
Where is the polar high?
Above 60 degrees N
300
What is fog caused by?
Cooling
400
What happens to air temperature as you increase in altitude?
Air temperature decreases
400
What happens to surface temperatures during La Nina?
It gets colder.
400
What are two of the global winds?
Trade Winds, Westerlies, Polar Easterlies, or Polar Front
400
Where is the polar low?
Below 60 degrees S
400
What are the three main types of clouds?
Cirrus, Cumulus, and Stratus
500
With temperature inversions, what happens to air temperature when air sinks to lower altitudes and is compressed?
The air temperature increases because the pressure of the surrounding air increases.
500
What do El Nino and La Nina influence?
The state of weather almost everywhere.
500
What three factors affect the wind?
Pressure Difference, The Coriolis Effect, and Friction
500
Where are Ferrel cells?
between 30 and 60 degrees N & S

What are the two reasons why local winds are caused?
Topographic effects and surface composition
