The winter storm Xynthia seen by altimetry

Category: Ocean and climate news

The storm Xynthia crossed Western Europe on 26-28 February 2010. The combined effects of a strong atmospheric depression, high tides and strong winds caused extreme damages.

The storm Xynthia crossed Western Europe on 26-28 February 2010. It caused extreme damages mainly in France due to floods.

Wind speed and significant wave heigths measured by altimetry satellites on the storm path indicate a speed more near than 20 m/s off Vigo (Spain) and waves between 4.5 m and 6 m on 2010/02/27 8:30.

A strong atmospheric depression, as observed during Xynthia, creates hills at the sea surface. The situation is even worse when the effects of a strong atmospheric depression and high tides and strong winds are combined.
