another signal of season change are the?

equinoxes

hurricanes

storms that form over the warm, tropical ocean waters

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

floods

water spreads over land

flood

melting snow or rainwater fills streams or rivers until they reach the flood stage

flood plain

water that floods into the surrounding area
