Abstract

The biophysical responses of the upper ocean to Typhoon Tingting in 2004 were analyzed using multiplatform satellites and Argo float data. Along Tingting's passages, multiplatform satellite instruments detected an increase in surface chlorophyll concentration (0.08 ~ 0.15 mg • m-3) and sea surface cooling (4~5 °C) in the wake. The wind fields intensified the oceanic cyclonic circulation, sea upwelling, surface cooling, and deepened the mixed layer (2O'-~35 m). The mixing and upwelling injected subsurface phytoplankton and nutrients into the surface layer, resulting in two-week-long phytoplankton blooms. The surface cooling and phytoplankton blooms occurred mainly in the pre-existing cyclonic circulation area, but few in the pre-existing anticyclonic circulation area. This work provided convincing evidence that negative sea surface features play important roles in biophysical responses of the upper ocean to typhoons.
