Convection currents
And pressure differences
Coriolis Effect
Rotation of the Earth
Westerlies
Where they blow from
Land heats up and cools down faster than water so convection currents are formed.

Boundary between air masses of different densities
Advancing warm air
Advancing cold air

6. A front where the boundary does not move
A cold front catches up and overtakes a
warm front cutting the warm air off from the ground
The ocean moderates the climate
Latitude
Altitude
Proximity to bodies of water
Proximity to mountains
Cools and condenses – releases moisture as rain/snow

7. Light to moderate precipitation
Thunderstorms and heavy rain
Rapid expansion of superheated air
Repeated updrafts in cumulonimbus clouds
Electrical discharge between the cloud base and the ground
Heat and moisture (out in tropical oceans)
Between 5 and 20 degrees latitude
High
Low
Polar, temperate, tropical
Reflectivity
Sun’s radiation is reflected back into space by glaciers and ice sheets, prolonging ice ages.
