Upper Meter Processes: Short Wind Waves, Surface Flow, and Micro-Turbulence
1998
Jaehne, Bernd | Klinke, Jochen | Zhang, Xin
The primary goal of this project is to advance the knowledge of small-scale air-sea interaction processes at the ocean surface, focussing on the dynamics of short waves, the surface flow field and the microturbulence. Since ground truth on the small-scale shape of the sea surface and the processes forming it is still widely missing, a better understanding of the physics of these upper meter processes is of utmost importance for the study of electromagnetic backscatter from the sea surface. The scientific objective of this research project includes the development and use of novel experimental methods based on imaging optical techniques to measure both short wind waves and the turbulence and flow field at the ocean interface. The area extended data resulting from these instruments are combined with meteorological ground truth to obtain a better insight into the dynamics of the interaction between short wind waves and the turbulent drift layer at the ocean surface as a function of wind stress, surface films, surface currents, and swell.
