Gulf Stream effect
Gulf Stream effect
Warm current carrying tropical heat to W Europe
Westerlies wind direction & latitude

West to east in mid-latitudes (30-60°)
Trade winds direction & latitude
Trade winds direction & latitude
East to west near equator (0-30°)
Polar easterlies
Polar easterlies
Cold winds from polar zones to mid-lats (60-90°)
Upwelling definition
Upwelling definition
Cold, nutrient-rich water rising from ocean depths
Temperature inversion
Temperature inversion
Warm air trapping cooler air near surface
Solar radiation at equator
Solar radiation at equator
Most direct & intense, hits surface directly
Water's heat capacity effect
Water's heat capacity effect
Absorbs & releases heat slowly, stabilises temps
Sea breeze
Sea breeze
Cool air from ocean moving inland during day
Microclimates
Microclimates
Small localised climate variations within larger regions
