Climate

• And Weather

2
Definitions climate

• The general or average weather conditions of a
  certain region, including temperature, rainfall,
  and wind. On Earth, climate is most affected by
  latitude, the tilt of the Earth's axis, the
  movements of the Earth's wind belts, the
  difference in temperatures of land and sea, and
  topography.

Definitions weather

• The state of the atmosphere at a given time and
  place, with respect to variables such as
  temperature, moisture, wind velocity, and
  barometric pressure.

Sun Drives Weather

• Solar energy strikes the Earth, heating unevenly
• Water moderates climate takes a great deal of
  energy to increase waters temperature

Earths Tilt

• Earth currently tilted 23.5 degrees
• Summer and winter solstice, sun in direct line
  with the Tropic of Cancer and the Tropic of
  Capricorn
• Autumn and Spring Equinox, crosses the Equator

Solar Energy

• Coriolis Effect Pattern of Energy Distribution
• Cosine Law More energy received at equator than
  at poles

Air Patterns

• Warm air holds more water vapor than cold air
• Warm air rises cold air sinks
• Warm air is low pressure cold air is high
  pressure

30ºN Tropics 30ºS

• Moist air in tropics rises, cools in upper
  atmosphere, drops back down.
• Cool dry air descends around 30º, sweeps along
  desert regions, picking up any moisture, and
  returns to tropics.
