摘要

Chlorophyll-a concentration change were observed by the geostationary satellite sensors carried by the Japanese Himawari 8 Advanced Himawari Imager (AHI) and the South Korean Geostationary Ocean Color Imager (GOCI). Numerical simulation was employed to analyze this typhoon's impact on the ocean environment to the northeast of Taiwan. The model result suggests that Typhoon Malakas generated an upper layer cyclonic eddy in the study area. This surface eddy was connected to a 100-m deep pre-existing eddy to form a stronger one that triggered the upwelling observed by satellites.
