Screening of severe storms for possible rogue waves
Coastal and Marine Engineering Research Institute Ltd (CAMERI) conducts wave measurements for Israel Ports Development & Assets Company Ltd (IPC) using IPC-owned Datawell directional waverider buoys at two locations near Israeli coast: Ashdod since April 1992 and Haifa since November 1993. Data from those measurements is used for different types of studies, including statistical and extreme value analysis. All major storms (peak of significant wave height Hs  over 6m) starting from December 2010 were searched for outstanding events, using time series of buoy displacements as extracted from buoys dataloggers. This method eliminates any possibility of interference-induced errors. Two such events were encountered: one of January 7, 2015 at Haifa, and the other of January 19, 2018 at Ashdod. For each such event the buoy manufacturer was contacted for their opinion and possible explanation. While the first event should most probably be considered as artifact, the second one (January 19, 2018) was most probably a real event which quantitative parameters were distorted by the buoy data processing procedure. This paper reports details about the event of January 19, 2018, including close correlation between wave and wind records.
