Paper Abstract

This paper discusses the relationship between the observations of submarine sand wave SAR images in Taiwan shoal and sea surface wind. A total of 43 SAR images over 11 years are collected and 496 profiles of sand wave SAR images are used, the wind are estimated from blended wind data and current direction is from mode. Results show submarine sand waves are observed by SAR under wind speed of 10 m/s, only littlie are imaged above 10 m/s. The number of observed sand waves reaches its maximum under the adverse wind direction, while the crosswind has its minimum. These support that low and middle wind speed and adverse wind direction are favorable for SAR imaging submarine sand waves, high wind speed and crosswind are unfavorable. The comparison between monthly mean wind speed and sand waves observed by SAR also shows a strong correlation between both, which is lower wind speeds, the higher probability of sand waves observed by SAR. This may indicate that the higher observation of the sand waves by SAR is partly due to wind speed.
