碩士 / 國立臺灣海洋大學 / 海洋環境資訊系 / 102 / There exists often cold water upwelling in Hoping coastal zone, especially in spring. In light of the extensive data, such a feature is speculated that the Kuroshio’s seasonal swing could play an important role. Because the Kuroshio Current flowing northward is blocked by I-Lan ridge, then partial water of the Kuroshio Current develops a cyclonical eddy in Hoping basin, leading to the cold water upwelling. The estimated swing range before running over the I-Lan ridge, located in the northeast of Hoping basin, 30~50 km to the east of the Hoping River estuary, is about 20 km. Generally speaking, the temperature drops in Hoping coastal zone occur more frequent in spring than in winter, and the magnitude of temperature drops is also larger in spring than in other seasons. In fall, some waters of high temperature and low salinity (less than 33.5psu), could intrude into the study area from I-Lan bay.
