Storm surge in the Adriatic Sea: observational and numerical diagnosis of an extreme event
Storm surge Adriatic Sea
2010/1/27
Storm surge events occur in the Adriatic Sea, in particular during autumn and winter, often producing flooding in Venice. Sea levels are forecasted by numerical models, which require wind and pressure...
Mediterranean offshore extreme wind analysis from the 44-year HIPOCAS database: different approaches towards the estimation of return periods and levels of extreme values
