For the characterization of the situations of extreme storms in particular, it is usual to use an Eulerian approach in which only assess the local conditions of waves, however, a Lagrangean approach the same phenomenon can be achieved monitoring the characteristics of each storm since their training to the dissipation. In order to assess the characteristics in terms of ocean storm of the 2013/2014 winter, this methodology was applied to three months of Era-interim significant wave height data. Ninety nine storms were identified and characterized regarding of maximum significant wave height in the track, storm area associated to the maximum significant wave height, storm life time, time of maximum significant wave height arising, maximum area in the track, time of maximum area arising, length of the track, mean direction of track, arise length of track mean direction of track arising, decay length of the track, mean direction of track decay, in North Atlantic, during this period. The characteristics o these storms were compared with the corresponding ones from a previous study that includes a ten year data set. The Hercules storm, that affected the western coast of Europe during early January as also analysed.
