On the role of wind modulation of internal solitary wave signatures in SAR images

The relationship between ocean surface dark/bright pattern of internal wave in SAR images and sea surface wind field is investigated. Two cases of satellite SAR images have ISWs are analyzed, and SAR signature of ISWs under different current and wind conditions are simulated. It is shown that the sequence of brighter and darker stripes of ISWs signatures in SAR images are relative to surface current. The wind direction and wind speed differences can affect the shape and brightness of ISWs stripes, but cannot change the sequence of the stripes.
