Why are tropical storms more frequent and stronger as a result of climate change, and why are they bringing more precipitation onto land than has been the case in the past?
Answer:
Tropical storms are powered by the thermal energy stored in near surface ocean water. The frequency and strength of tropical storms has increased in recent decades as a result of this change. Larger storms developed in a warmer atmosphere can extract more water from the oceans, and so tropical storms are transporting much more water onto land, resulting in serious flooding. Flooding is also exacerbated because of an increase in the area of impermeable surfaces due to residential and commercial development and construction of more and bigger roads and highways.
