  1. Atmosheric Circulation Part II Important Concepts to remember: Redistribution of Heat Effects of Rotation The role of friction Conservation of angular momentum

  2. Seasonal Heating

  3. Differential Heating From Equators to Poles

  4. Non rotating view of Atmospheric Circulation High Pressure Low Pressure

  5. Schematic depiction of the development of the atmospheric circulation,starting from a state of rest Easterlies (Trades) Westerlies Redistribution of Heat – Large scale convective Cells

  6. Rotation effects, the Coriolis Force

  7. Some practical rules to remember: Fpressure Low Pressure High Pressure FCoriolis • Particle will have the Coriolis force 90 degrees to the right • Particles will tend to move along line of constant pressure • Particles will have the high pressure on their right (same as Coriolis)

  8. Schematic depiction of the development of the atmospheric circulation,starting from a state of rest Easterlies (Trades) Westerlies

  9. Problem? Circulation in the atmosphere

  10. Role of Friction
