Abstract	In early 2008, cold water in the Taiwan Strait (TWS) was moved sequentially by a cross-strait flow and a southward flow to the Penghu Island, causing a cold-related fish kill disaster. Except for the local wind forcing, the coastal-trapped waves (CTWs), intermittently propagating toward the TWS from north in winter, are an additional factor that could impact the flow patterns by changing cross-strait sea-level gradient during the disaster. In the first stage (January 28–February 7), the reach of a large CTW trough induced an additional northward flow, which formed a cyclone after turning around the Zhangyun Ridge. Then, the cyclone led to an additional cross flow, which enhanced an eastward (offshore) movement of cold water. In the second stage (February 7–14), the arrival of a large CTW crest triggered an additional southward flow, which intensified a southward movement of the cold water. Due to the additional eastward and southward movements caused by the CTWs, the cold water could reach Penghu Island inducing a cold disaster.
