Modeling of extreme ocean waves and ocean wave climate on mesoscale

(Modellering av ekstreme havbølger og havbølgeklima på mesoskala)


This is a three-year project funded by the BeMatA program of the Norwegian Research Council (contract 139177/431).

The project focuses on analysis and simulation of extreme ocean waves and ocean wave climate. It is a coordinated effort between the Department of Mathematics at the University of Bergen, the Department of Mathematical Sciences at NTNU in Trondheim, the Institute of Applied Mathematics at SINTEF in Oslo (until July 2002), and the Department of Mathematics at the University of Oslo (from August 2002).

For a description of our activities look at the web-page in the appropriate language:

Freakbølger, ekstreme bølger og havbølgeklima
Freak waves, rogue waves, extreme waves and ocean wave climate
Olas gigantes, olas extremas y clima de olas marinas
