Urban Heat Island - Specific Flashcards
1
Q
What is urban heat island effect
A
Highest temps = industrial built up areas such as CBD = low albedo
2
Q
What is temp sink
A
Pockets of air above parks and small bodies of water
3
Q
Why thunderstorms are more frequent in urban areas (5)
A
UHI = urban areas warm = hold more water
Warm moist area rises = conventional uplift
Cools, condenses + rains = conventional
Air rising = lower pressure
Buildings promote vertical uplift + water vapour from industries and power stations
Condensation nucleis = clouds form
4
Q

A
25%
Particularly in hot humid conditions
Late summer afternoons
