摘要
Abstract
Princeton Ocean Model (POM) is employed to investigate the Taiwan Warm Current (TWC) and its seasonal variations. Results show that the TWC exhibits pronounced seasonal variations in its sources
strength and flow patterns. In summer
the TWC flows northeast in straight way and reaches around 32°N; it comes mainly from the Taiwan Strait
while its lower part is from the shelf-intrusion of the Kuroshio subsurface water (KSSW). In winter
coming mainly from the shelf-intrusion of the Kuroshio northeast of Taiwan
the TWC flows northward in a winding way and reaches up around 30°N. The Kuroshio intrusion also has distinct seasonal patterns. The shelf-intrusion of KSSW by upwelling is almost the same in four seasons with a little difference in strength; it is a persistent source of the TWC. However
Kuroshio surface water (KSW) can not intrude onto the shelf in summer
while in winter the intrusion of KSW always occurs. Additional experiments were conducted to examine effects of winds and transport through the Taiwan Strait on the TWC. In winter
northerly winds enhance the shelf-intrusion of the Kuroshio and spread northward
but hamper the northward inflow from the Taiwan Strait. In summer
the effect of the winds is confined in the surface layer
and less obvious than that of winter. Transport through the Taiwan Strait influences the TWC significantly. With the Taiwan Strait closed in the simulation
the TWC would be dramatically weakened.
