Urban Heat Island Rainfall Increase
The urban heat island effect can increase local rainfall by up to 30%. The table shows this effect on an area with a baseline rainfall of 50 mm. All of the following statements are true EXCEPT:
| Scenario | Baseline Rainfall (mm) | Urban Rainfall (mm) |
|---|---|---|
| Without Heat Island | 50 | 50 |
| With Urban Heat Island | 50 | 65 |
A
For a baseline rainfall of 50 mm, the urban heat island effect produces an increased rainfall of 20 mm.
B
The urban rainfall in the presence of a heat island is given by mm.
C
Enhanced moisture in heated urban regions can lead to increased precipitation.
D
A 30% increase on 50 mm yields an additional 15 mm of rainfall.
