Sea Surface Cold Water near the Southeastern Coast of Korea: Wind Effect
변상경,Byun, Sang-Kyung The Korean Society of Oceanography 1989 韓國海洋學會誌 Vol.24 No.3
Cold water observed at sea surface near the southeastern coast of Korea in summers 1982 and 1983 was studied by using data of hydrography, sea level, wind and satellite image. In summer season when water column shows 3-layered structure a "full" upwelling occurs by southwesterly transient wind continuing for several days. During upwelling event, surface water of high temperature moved offshore, middle water of low temperature outcropped to the sea surface, and sea level was lowered, however, equilibrium depth of surface layer was not changed. It may be concluded that cold water at the surface originates from middle layer and strong surface front is a result of surfacing of seasonal thermocline. In order to see the relationship between position of surface front and wind input, a model of Csanady (1982) was applied in a rigid lid approximation. The results show that frontal position can be determined by wind input and water structure near the southeastern coast of Korea. Cold water in summer can appear at the sea surface only when there is wind larger than a minimum wind impulse of order $10m^2/sec$.

On the basis of oceanographic observation conducted in summer 1982, the flow pattern of the Tsushima Warm Current definitely showed two branches with high surface velocity more than 70 cm/sec in the western channel of Korea Strait. One of the branches, the East Korea Warm Current, found about 8 km off Pusan flows northward along the east coast of Korea and the other branch, located at about 20km off Pusan flows east after passing the Korea Strait. The branching of two flows already occurred before the Tsushima Warm Current reaches the Pusan Tsushima section, and the volume transport and the widths of the two branches are not much different from each other. The number of branches may be controlled by the width of western channel and the flow of two branches may also be related to the variation of layer depth and the widening ratio of widths between the western channel and the Japan Sea (East Sea).

해앙에서 강우에 의하여 발생된 수중잡음의 특성을 밝히기 위하여 한국 동해의 연안에서 비가 내리는 동안 해수중 주위잡음을 측정하였다. 수심 200 m인 정점에서 세 개의 수중청음기를 각각 수심 30 m, 50 m및 100 m에 설치하였다. 먼저 강우상도가 1.5~23.4 mm/h일 때 강우잡음의 스펙트럼 특성을 주의깊게 조사하였다. 그리고 다양한 주파수에 있어서 스펙트럼레벨과 강우강도와의 관련을 조사하였다. 또한, 수중청음기로 수신한 강우잡음의 파형을 관찰하여 강우에 의한 수중잡음의 발생기구에 대하여 고찰하였다. In order to investigate the characteristics of oceanic rain noise, we measured ambient noise at a site on the east coast of the Korean Peninsula while it rained. Three hydrophones were placed at a depth of 30 m, 50 m, and 100 m respectively where the water depth was 200 m. The spectral characteristics of rain noise were carefully examined according to rainfall rates between 1.5 and 23.4 mm/h. And the dependence of spectral level on rainfall rate was investigated for various frequencies. Also, it was considered the generation mechanism of rain noise by means of observation of rain noise waveforms received by hydrophone.
