Field program in the Yellow and East China shelf seas for understanding ocean process has been carried out during summer, 2007. CTD casting before and after the typhoon Nari passed across the East China Sea toward Korean peninsula. Ocean drifters as well as ADCP have been deployed before the typhoon Nari approached.
This presentation will include the observed features for ocean response under the typhoon Nari and some interesting findings for the current response implying vertical mixing down to near bottom and up to the surface when the typhoon passed by the moored ADCPs. Cold water mass after the typhoon passed through the region persisted over nearly 10 days or more, which has been verified from surface temperature observed by the deployed drifters.
General introduction for research program is presented during the presentation as well as some introduction to the field findings during the 1st year program since the program is initiated.
