@@ It is well known that upwelling of subsurface water is dominant around the Taiwan Bank (TB) and the Peng-Hu (PH) Islands south of the Taiwan Strait in summertime (Figure 1). The purpose of present study is to investigate and describe the summertime upwelling in the area around the TB and the PH Islands using the high-resolution SST fronts together with the satellite SST and Chl-a images. SST frontal features and related phenomena around the TB-upwelling and the PH-upwelling were investigated by using long-term AVHRR (1996-2005) and SeaWiFS (1998-2005) data received at the station of National Taiwan Ocean University.
