What three forces affect air movement?
- Pressure gradient force(from hight to low)
- Coriolis effect(air deflected)
- Friction
What are the four atmospheric lifting mechanisms?
- Convergence
- Convection
- Orographic lifting
- Frontal lifting
Bring air to saturation.
What conditions are necessary in order for thunderstorms to form?
- Moisture
- Instability
- Lift
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.
What kind of conditions prevail over West and East coasts?

- West coast - dry because of the presence of cold water currents.
What are the three common cloud types?
- Cumulus.
- Stratus.
- Cirrus.
Seasons.
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)
