Geography
Physical Environments
Weather
Factors Affecting
Latitude
Closer to poles = Colder
More sky for sun to go through t/f more energy absorbed by sky, not land.
Energy is spread over a larger area b/c earth curvature t/f less energy per square metre.
Albedo Effect
Ice/snow reflects energy
Up to 90% lost
Earth's Tilt
Poles get 6 months sun p.a, w/a Equator gets 12 months sun p.a.
Altitude/Relief
Temperature
-1K/100m
Precipitation
A Cross Section of the UK
East of UK is drier than west b/c of rain shadow.
Orographic Precipitation = Relief Rainfall
Aspect
North facing slopes = colder
Receives less energy
North facing Ski Slopes
Distance From Sea
Sea = "big-ass temperature controller"
Regulates extremes of winter and summer
Water has higher heat capacity than air
Currents
UK is kept warm by North Atlantic Drift
Air Masses
Arctic Maritime
Super-cold and wet
From North Pole

Fairly common
From Greenland
Polar Continental
Dry but cold as a snowman's toes
Siberian
"Beast from the East"
Effects
Freezing
Black ice
Freezing fog
Airports, power lines
Burst pipes
Prolongs existing snow
Tropical Continental
Hot and dry
African
