'1000 Year' Flooding in South Carolina

Author: Hugh Bollinger/Monday, October 5, 2015/Categories: natural history, sustainability, environment, climate change

Rains and floods, described as "Biblical", are hitting South Carolina and surrounding regions. Parts of that state received in excess of 21-24 inches of rain during a 3 day period exceeding previous records by 3-5 inches of precipitation.

A map from the Earth Simulator, created by Japan's  Center for Earth Information and Science  shows new capabilities of prediction, if not prevention, for extreme weather events. The connection between coastal regions of the southeaster USA and the Atlantic is obvious in a 'big data' visualization of a low pressure "river" of moisture fueling bands produced by Hurricane Joaquin swirling north. The bands from the combine vortexes reach to the coast causing whipping pulses of cyclonic winds, rains, and floods. More rain is predicted before the hurricane moves further north.

What remains to be determined is the influence of ongoing climate change with higher ocean temperatures and a warmer atmosphere's capacity to hold more moisture. Models like the Earth Simulator can help.

If predictive models can confirm those connections, similar flooding events could easily become more frequent than every 1000 years.
