Gulf of Mexico researchers examine effects of Hurricane Harvey floodwaters

What happens when a hurricane sends fresh rainwater — up to 124.9 trillion L (33 trillion gal) of it — into the saltwater ocean? In the case of normal-sized storms, the rainwater, which is less dense than saltwater, typically sits atop the ocean in a distinct “blob,” which generally mixes into the ocean within hours […]

‘Rainstorm generator’ predicts more frequent – but less intense – dryland thunderstorms

In the lowest and most arid parts of the Colorado River basin, moisture from the ground rises into the atmosphere before condensing rapidly to form frequent and sudden thunderstorms. These storms, which typically control the flow of runoff, provide irrigation for river-bank plants, supplement water supplies, and affect the chance that the river will flood, […]

Coastal wetlands play key role in reducing flood damages from storm surge, study finds

The presence of coastal wetlands along the northeastern U.S. likely reduced flood damages during Superstorm Sandy in 2012 by at least $625 million, according to a recently published peer-reviewed journal article. As part of the same study, researchers also determined that salt marshes within Barnegat Bay on New Jersey’s coast can be expected to decrease […]
