Monitoring of ocean waves made possible with the help of satellites

With the help of radar stations installed on some satellites, it became possible to obtain very necessary information, in particular, about the height of waves in the North Sea.

As you know, the height and frequency of waves in a large reservoir largely depends on the wind speed. Today satellites equipped with special radar sensors can measure wind speed over the ocean surface at several points at once.

By analyzing surface roughness, radars measure the reflectivity of water. The maximum reflection corresponds to “rough” water, that is, the area of ​​the sea exposed to the strongest winds. Wind stripes indicate the direction of the wind in the obtained radar images.

Information about the huge waves in the North Sea for ships, oil platforms and wind farms comes from satellites of the European Space Agency. After appropriate computer processing, a model is formed that helps to predict the place of occurrence of hazardous waves.
