고주파 해수면관측레이더를 활용한 제주해협 표층해류 관측

Abstract

To observe the surface current fields in the Cheju Strait, a pair of SeaSonde high frequency (HF) radar of 13 MHz was installed at two sites of Cheju-do (Aewol and Kimyung)in late December 2011 and operated normally from mid February 2012. A comparison between surface current velocities measured by HF radar and moored acoustic Doppler current profiler (ADCP) shows a good relationship with the correlation coefficient of 0.94 and the root-mean-square velocity difference of 11.6 cm/s in major axis of principal component. The mean current field measured by HF radar is well represented the Cheju Warm Current that rounds Cheju-do clockwise and passes to the east through the southern part of Cheju Straits.
