Rouge Waves: The Science of Huge Ocean Waves

Read Summary
Summary

Rogue waves are a specific type of ocean wave that can be much larger and steeper than other waves. They are often responsible for shipwrecks and other losses at sea. While some large waves are predictable, rogue waves can come from unexpected directions and are not easily detected with standard wave-height sensors. However, new technologies such as the Draupner Platform and synthetic aperture radar are helping to identify and measure rogue waves, allowing for advance warning to ships at sea. The German Space Agency is using satellite data to create a map of rogue waves, which offers global coverage compared to the limited data gathered from buoys and oil platforms.

Rouge waves

Many kinds of ocean waves exist, but some of them huge waves. In fact all large waves are Rouge waves. Coastal landslides produce tidal waves whereas undersea earthquakes cause tsunamis. These can be considered as rouges which are predictable. Rouge waves are steeper than other waves. From 1990 onwards the sailors and scientists started to suspect the rogue ways that are responsible for many losses at sea. Rouge waves can be measured with the instrument known as Draupner Platform.

Rouge wages do not occur alone and it is followed with a sequence known as “Three Sisters”. Rouge wave starts with one huge wave and followed with two huge waves. At present, the rouge waves are predictable. Rouge Waves are greater than twice the size of the significant wave heights and sometimes come from unexpected directions rather than prevailing waves.

Many Rouge Waves caused the sinking of vessels, large container ships and supertankers for past decades. Rogue waves are more common than anyone had expected. The ERS satellite and other radar satellites can detect he gigantic rouge waves. ESA and ERS satellites helped to identify the Rouge Waves through synthetic aperture radar. Accordingly software also developed to detect rouge waves from radar images so that advance warning available to ships at sea.

The German Space Agency scientists are able to offer rouge-wave map with the advantage of satellites global coverage with the data gathered from European Space Agency satellites (ESA). Besides satellite data, small number of buoys/oil platforms collects the data about the rouge waves. But when high waves appear the wave-height sensors sometimes damaged.
