Campos, R. and Guedes Soares, C. (2012), “Comparisons of two wind and wave data sets from the North Atlantic”, Maritime Engineering and Technology, Guedes Soares et al. (Eds),Taylor & Francis Group, London, pp. 473-479
This paper compares two wave data sets: HIPOCAS and NOAA/NCEP. HIPOCAS is a hindcast developed under a European project and it is a result of the wave model WAM-cicle4 forced by REMO surface wind fields. The wave data set of NOAA/NCEP is a forecast that has been continually performed by WAVEWATCH III since 1997, forced by GFS surface wind fields. In order to compare the described data sets, coincident time period and area were determined, which corresponds to 1997 to 2001, latitudes between 20? and 68? North and longitudes between 50? West and 04? East. The differences for the mean values and for the 99% exceedance level were calculated. Small divergences between the two data sets are identified in standard weather conditions in the North Atlantic. However, the longitudinal evolution of the differences is extremely marked in both wave and wind fields. There is an important increase of differences for extreme situations, which is mainly due to the differences of the meridional surface wind component, occurred during the winter.
