  1. What three forces affect air movement?
    • Pressure gradient force(from hight to low)
    • Coriolis effect(air deflected)
    • Friction
  2. What are the four atmospheric lifting mechanisms?
    • Convergence
    • Convection
    • Orographic lifting
    • Frontal lifting

    Bring air to saturation.
  3. What conditions are necessary in order for thunderstorms to form?
    • Moisture
    • Instability
    • Lift
  4. What happens during El-Nino?
    • Easterly trade winds reverse. In the Pacific Ocean upwelling is suppressed.
    • Dry conditions over northern Australia. Wet conditions over South America.
    • Famine, flooding, drought occur.
  5. What kind of conditions prevail over West and East coasts?
    • East coast- more precipitation because of the presence of warm water currents.
    • West coast - dry because of the presence of cold water currents.
  6. What are the three common cloud types?
    • Cumulus.
    • Stratus.
    • Cirrus.
  7. Seasons.
  8. What is the energy balance equation?
    SW↓ - SW↑ - LW↑ + LW↓ = S + L + G + M


    • S = sensible heat flux
    • L = latent heat flux(evaporation)
    • G = ground heat flux
    • M = metabolic heat flux(photosynthesis)
