Weather vs. Climate

• Weather-condition of atmosphere at a particular
  location and time
• Climate-weather conditions at a particular
  location over a long period of time

8
Precipitation

• Convectional-caused by heated, rising air
• Orographic-mountains block moist air forcing it
  to rise
• Frontal-occurs when cold fronts push up warm
  fronts.

9
Hurricanes (Typhoons)

• Form over warm, tropical ocean waters
• Hurricanes typically blow west.

10
Tornado

14
Climate-Wind Currents

• Distributes suns heat from one part of the world
  to another through convection

15
Climate-Ocean Currents

• Like rivers flowing in ocean
• Warm water flows from equator toward poles

16
Climate-Zones of Latitude

• Low/Tropical
• Tropic of Cancer to Tropic of Capricorn
• hot all year long

• between tropics and polar regions
• climate varies greatly
• High/Polar
• encircle North and South Poles
• cold all year long

17
Elevation

• Highercolder
• Every 1000 ft. temperature drops 3.5 degrees

18
Topography

• Landforms affect climate
• Mountains
• Temperature
• Precipitation

19
El Niño/La Niña

• Warming of the waters off the west coast of South
  America
• Natural change in climate
• Brings heavy rains to Americas
• La Niña is reverse-it brings heavy rain to
  western Pacific

20
Global Warming

• Air temperature is rising
• Increased 1 degree in last 100 years
• Greenhouse effect-layer of gases released by
  burning of coal and petroleum traps solar energy
