摘要

In this paper, we discuss the kinematic properties of the mesoscale features in the Taiwan Strait (TS). Two kinds of mesoscale features can be seen in the TS. One is the shear wave; it is a lateral wavelike train with phase speed and wave period. The other one is the eddy-like cold-water wedge; it mainly rotates with a little translation. The shear wave mainly occurs in the boundary of the China cold water along the western TS in winter and spring. The eddy-like cold-water wedge can be seen in the mid-winter when the strong southward China coastal cold water covers up most of the northern TS and creates a very unstable front with the northward warm water. In this study, selected NOAA satellite AVHRR channel 4 infrared images during 2000-2003 are considered to detect the movement of the above mesoscale features through a feature-tracking method. It is found that the development of these features is highly related to the monsoon winds. Meanwhile, the local tidal pattern can also affect their movements.
