climate
weather conditions at a particular location
water vapor
determines the weather there will be precipitation
cloud covers
may hold water vapor
elevation above sea level
air becomes thinner and looses its ability to hold mositure
air movement
winds move the air and the solar energy and moisture that it holds, as a result, weather can change very rapidily
precipitations
amount of water vapor in the air and the movement of the air
orographic precipitation
falls on the windward side of hills or mountains that block moist air and force it upward
frontal movement
causes most precipitation in the middle latitudes
front
boundary b/w air masses of different temperatures or density. the boundary b/w two air masses is pushed upward
weather
as air masses warm and cool and move across the earth's surface
hurricane
air flowing over an ocean with a temp of at least 80 degree F picks up huge amounts of moisture
hurricane
water-laden winds flow into a low pressure core they tighten to form an eye usually about 10-20 miles across and has clear, calm skies
hurricane
the clouds and winds stretch over a large area and can be as wide as 500 miles
hurricane
upper air currents blowing from the east steer the hurricanes in westerly direction
hurricane
as it hits land, it pounds the area with heavy winds and rains also causes storm surges across the region
tornadoes
twisters, powerful funnel shaped column of spiraling air
tornado
form quickly and sometimes w/o warning
tornado
born from strong thunderstorms; these are capable of alot of damage
tornado
winds swirl counter-clockwise around a low pressure center
tornado
winds can reach up to 300mph
tornado
generally have small diameters (300 feet), travel about a mile and last only a few minutes but the largest are the most powerful
blizzard
A heavy snowstorm with strong winds more that 35mph
blizzard
cause traffic hazards and endanger livestock
droughts
long period of time without rain or very minimal rainfall
drought
lack of rain results in crop failures and drastically reduced levels in water storage facilities
drought
early 1930s a drought hit the Great Plains in the US
drought
dust storms damaged farms across a 150,000 square-mile region that became known as the dust bowl
