AP environmental science
wind system that influences large climate and reverses direction seasonally
every 4-12 years, cools ocean surface on west
vertical and horizontal wind patterns
every 3-7 years, lasts 1 year
region of ocean near equator with calm winds
high speed currents, affect local weather
winds below latitude 60 degrees
travel S. and W. in northern hemisphere, west to north in southern hemisphere
constant weather patterns after 30 years. ex-avg. temp. and precipitation
80 km above earth's surface, where meteors burn up
110 km above Earth's surface, thinnest gas layer; absorbs solar wind and reflects radio waves
top of troposphere, temperature is high b/c of thin ozone
temp. when water vapor condenses to water
holds lots of moisture
winds in N hemisphere deflect right, south winds deflect left
traps solar radiation
10-20 km, where ALL weather takes place and clouds
layer of gas held close to Earth b/c of gravity
why Earth unevenly heated
1) more solar rays hit equator than poles. 2)tilt points away or closer to sun. 3) equator moves quicker than poles.
