: Cities are increasingly adopting "sponge city" concepts—using permeable surfaces and green roofs to absorb rainfall naturally rather than funneling it into overtaxed pipes.
: As the atmosphere warms, it can hold more moisture (roughly 7% more for every degree Celsius). This is leading to an increase in the frequency and intensity of extreme rainfall events globally. 4. Safety and Preparation Gewitterregen
: Inside the cloud, turbulent updrafts and downdrafts cause water droplets and ice crystals to collide. This interaction generates static electricity (leading to lightning) and allows droplets to grow rapidly into heavy raindrops or hail. 2. Characteristics of the Rain low pressure Cold fronts
Extreme rainfall: how cities are preparing for wetter futures Gewitterregen
: Seek shelter in a sturdy building. Avoid low-lying areas or underpasses where water can collect rapidly.
