Abstract: abstract:Multi-satellite remote sensing data and Regional Ocean Model System (ROMS) are employed to examine the physical and biological responses to Typhoon Nakri during 1-8 June 2008 in the western North Pacific. From satellite observations, a remarkable surface cooling (~5 °C) and a distinct phytoplankton enhancement were found after Nakri’s passage. However, it is noted that, in contrast to the well-documented rightward bias of the surface cooling response, the maximum biological response to Nakri occurred to the left of the Nakri’s track rather than the right side, whereas the most distinct cooling response occurred. Numerical experiments with and without the influence of preexisting cyclonic circulation and previous typhoon are conducted to resolve the dynamic mechanism therein. Results from simulations show that both the physical and biological responses to Nakri are greatly affected by the preexisting cyclonic circulations. Nevertheless, the discrepancy between the locations of maximum physical and biological responses was mainly a result of the advance uplift of nutrient fields by previous typhoon Rammasun, which passed through the area about two weeks before Nakri.
