1
10.3 Distributing the Heat p. 388 -396 Energy from the sun radiates to the Earth and is absorbed unequally on the planet.
2
Why do some areas absorb more radiation than others? Earth’s tilt on axis
3
Albedo effect Ice, snow, clouds reflect Darker land absorbs
4
How Oceans Effect Distribution of Heat Large Reservoirs of Heat 1.Water has high specific heat capacity 2.Water has low albedo, high absorption (90% of incoming solar radiation is absorbed
5
Large Reservoirs of Heat 3. High heats of fusion and vaporization 4. Water is a fluid and heat can be distributed
6
Ocean Currents Large effect on weather in coastal communities Influence worldwide climate
7
Gulf Stream Surface current: starts in Caribbean and flows up the Eastern coastline of US and Canada up to British Isles. Also called North Atlantic Drift.
8
El Nino Wind Direction over the South Pacific reverses and winds flow eastward Heavy rains on west coast of S. America, drought in SE Asia and N Australia
9
How does El Nino effect N America? While most of effects of El Nino are (-) (floods, drought, famine) it does cause warming in western N. America in winter months and a decrease in intensity of Atlantic hurricanes and tornadoes in Canada and US
10
What is La Nina? Increase strength of westward winds = cooling of surface waters of eastern equatorial Pacific Warmer air to S Asia, Australia
11
Effects of La Nina in N. America Cold air from Alaska moves S across western Canada and US (1996 LONG winter!) East becomes warmer and drier
12
Prevailing Winds
13
4 main prevailing winds
14
Coriolis Effect
15
Jet Stream
16
Ocean Breezes
