为研究“天兔”台风对北部湾海洋环境造成的实时影响, 在台风经过期间运用岸基高频海态雷达对北部湾海洋进行遥感探测。根据海洋回波多普勒频谱的形成机理, 以及回波频谱特性随风信息变化而发生改变的原理, 从台风环境下的雷达回波信息中提取风信息参数, 并把它应用于“天兔”台风影响下的北部湾海域, 进而形成实时的海域风场信息, 为研究台风海况下的北部湾海洋环境提供风场信息支持。

HF shore-based radar was deployed to investigate the real-time effect on the marine environment of the Beibu Gulf during typhoon period. Wind field parameters retrieved from sea echo, by means of the forming mechanism of sea echo Doppler spectrum and wind-driven principle of echo spectrum, were applied to study the marine environment of the Beibu Gulf during Typhoon Usagi. The dta contained real-time wind field information in the Beibu Gulf, which provided support for the deep current inversion of the Beibu Gulf under typhoon condition.
