Global Atmospheric Circulation
- Thermohaline Condition
- 1) Water freezes at the poles.
- 2) The surrounding water becomes more salty and therefore more dense.
- 3) Water begins to sink as density increases.
- 4) Sinking of dense water allows warm water to rise to the surface.
- 5) Warm water cools and sinks.
- Global Climate Zones
- Winds move from high pressure to low pressure.
- Air rises where the Hadley cells - this creates low pressure = high rainfall, high temperature.
- Air sinks where the Hadley and Ferrel cells meet - this creates high pressure = high temperature, low rainfall.
- Air from Polar cells sink - creates high pressure = low temperature, low rainfall.
