Rogue Waves Becoming More Extreme
Research by the University of Southampton suggests that rogue waves are happening less often but are becoming more extreme.
Waves are classed as rogue when they are over twice the height of the average sea state around them. From trough to peak, past observations have put some at over 30 meters (98 feet) high. When at their fiercest, they are capable of damaging or sinking ships, can wound or kill crew members and on occasions have swept people off the shoreline and out to sea.
From the University of Southampton and The National Oceanography Centre (NOC), a team studied over 20 years of information (sourced between 1994-2016) from 15 buoys which provide surface data along the U.S. western seaboard – stretching from Seattle to San Diego.
The data showed that instances of rogue waves fell slightly, but that rogue wave size increased, relative to the background sea. Rogue waves are more severe and common in the winter months and are now happening with increasing frequency within calmer background seas.
