In this paper, we present the synthetic aperture radar (SAR) observation of the detailed sea surface wind patterns associated with fetch in the Bohai Sea, China. We then implemented the WRF model to simulate the entire processes of this weather event. WRF model results show the dynamics and evolution of this event.
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...
SAR-derived wind measurements are in the process of being implemented for operational production within NOAA's National Environmental Satellite, Data, and Information Service. For C-band ENVISAT and RADARSAT-1/2 data, the CMOD5 algorithm is being used; for ALOS data, a special L-band wind algorithm is employed. Comparisons of both C-band and L-band winds with ASCAT scatterometer wind measurements...
Marine atmospheric boundary phenomena, i.e., atmospheric gravity waves (AGW), vortex streets and boundary rolls, modulate the surface wind field and will leave imprints visible on synthetic aperture radar (SAR) images. In this case study, we present an ENVISAT SAR observation of AGW offshore of the mountain Laoshan along the yellow sea coast of China. The Weather Research and Forecasting (WRF) weather...
High spatial resolutions synthetic aperture radar (SAR) retrieved ocean surface wind field under actual conditions can be affected by several ocean surface features, such as artificial object, surface oil slicks and air-sea boundary layer stabilities etc. In this paper we present several case studies of those impacts, and a semi-empirical model to correct the air-sea boundary layer stabilities. We...
Synthetic aperture radar (SAR) observes the large-scale ocean surface wind field. With SAR instruments, we can actively monitor phenomena in the coastal ocean and marine atmospheric boundary layer at very high spatial resolution (on the order of tens of meters) in all weather conditions day and night. SAR observations are particularly useful in coastal regions where clouds are usually present, causing...
