Albedo
building material
anticyclone
Retains heat/ high storage capacity
reflects heat
(less) mixing if warm air with cold air aloft
surfaces that shed water
radiates heat
less surface water
extra sources of heat
pollution from cars etc. traps heat at night
less wind chill
less wind
steep roof
people, industry, cars, central heating
plants cool air through transpiration
Writing Frame
