1 Physical Oceanography of the Yellow and East China Sea Dr. Steven R. Ramp Research Professor Naval Postgraduate School

2 Bottom Topography of the East China Sea. The proposed ASIAEX study region is indicated

3 General Circulation of the Yellow and East China Sea [from Chen et al., 1986]

4 Mean surface currents in the ECS, averaged from 31 years of GEK data. [from Qiu and Imasato, 1990]

5 Bi-Modal Structure of the Kuroshio Exiting the ECS Northern PositionSouthern Position [from Feng et al., 2000]

6 Velocity and Potential Vorticity Cross-Sections From the Kuroshio Near the ASIAEX Study Region Alongshore VelocityPotential Vorticity

7 Temperature Salinity Bottom Surface Yellow Sea T/S Characteristics: Winter

8 Temperature Salinity Bottom Surface Yellow Sea T/S Characteristics: Summer

9 M2 (semidiurnal) Tidal Ellipses in the Yellow and East China Sea [from Larsen et al., 1985]

10 Residual Tidal Currents in the Yellow Sea from the Lee and Beardsley (1999) stratified model. These currents result from the rectification of tidal currents by topography.

11 Surface Temperature Fronts in the Yellow and East China Sea [from Hickox et al., 2000]

12 East China Sea ASIAEX Site Locator Map CTD Transect * Mooring Site

13 Across-Shelf Temperature and Salinity Sections From the ASIAEX Pilot Study Cruise, April 2000 Temperature Salinity

14 Along and Across-Shore ADCP Velocity Sections ASIAEX Pilot Study Cruise, April 2000

15 Alongshore (red) and Across-shore (blue) velocity components from the ASIAEX mooring, ECS Shelf

16 Expanded x-axis to show internal solitary waves

17 Expanded Even more…..

18 Soliton Distributions in the Central Yellow Sea From Hsu et al., 2000
