Watermasses from the South China Sea to the Region East of Taiwan: a PIES Array to Explore Transformation Mechanisms along the Kuroshio
Abstract
Short Work Statement: We propose to investigate the evolution and decay of westward propagating meso-scaleeddies and the associated downscale cascade of energy when these eddies impinge on thesteep topography along Taiwan in the western North Pacific. The study area lies alongthe Kuroshio~s path between the Luzon Strait in the upstream direction and the EastChina Sea in the downstream direction. The study area is continually inundated withmeso-scale eddies arriving from the east. We propose to investigate the evolution and decay of westward propagating meso-scale eddies and the associated downscale cascade of energy when these eddies impinge on the steep topography along Taiwan in the western North Pacific. The study area lies along the Kuroshio’s path between the Luzon Strait in the upstream direction and the East China Sea in the downstream direction. The study area is continually inundated with meso-scale eddies arriving from the east. The study comprises (1) an observational array with moored instruments to be deployed for 1 year, (2) shipboard measurements taken during deployment and recovery cruises, and (3) measurements from glider(s) flying both through the moored array and within eddies as they approach the array. The in situ observations will be analyzed in conjunction with historical hydrography from the region. In addition, satellite altimetry, tide gauge data, and previously collected in situ time series from the western North Pacific will be used to interpret the observations from this proposed field program. Further, results will be interpreted in context of both idealized and realistic numerical model output. This proposal describes research to be conducted by M. Andres at Woods Hole Oceanographic Institution (WHOI) as part of a collaborative field experiment with researchers at National Taiwan University (NTU, S. Jan, Y.J. Yang and M.-H. Chang) and will coordinate with other U.S. researchers’ efforts in the region
