Urban heat islands and microclimates

Temperature inversions

Temperatures usually decrease with height through the troposphere. A temperature inversion is when the normal conditions are reversed and warm air lies above cold air. It can cause the build up of pollutants and smog.

Microclimates

Urban Microclimates

Climate feature:Distinctive urban features: Temperature Buildings retain and release heat more strongly than in rural areas, temperatures are higher than in surrounding areas. Tarmac surfaces are heated intensely and then strongly heat the air above it. Winds Two main processes occur as a result of high-rise buildings. Wind can be 'channelled' between high-rise buildings…
