Wave height characteristics in the north Atlantic ocean: A new approach based on statistical and geometrical techniques
The main characteristics of the significant wave height in an area of increased interest, the north Atlantic ocean, are studied based on satellite records and corresponding simulations obtained from the numerical wave prediction model WAM. The two data sets are analyzed by means of a variety of stat...
