Analysis and Synthesis of Data From the WISE/VANS 2005-06 and NLIWI/SCOPE 2007 Field Experiments

摘要

The objective of this grant is to improve understanding of how the large-amplitude internal waves and tides in the northeastern South China Sea are generated via interaction of the barotropic tide with the ridges and islands in the Luzon Strait. In addition to the problem's inherent scientific interest, understanding the generation problem is essential for developing a forecast model to predict the wave characteristics in the deep basin and on the Chinese continental slope and shelf. The approach is to analyze two data sets obtained in the South China Sea in the context of large amplitude, nonlinear internal wave theory. The data sets were obtained during the Windy Islands Soliton Experiment / Variability Around the Northern South China Sea (WISE/VANS) experiment from April 2005 to June 2006 and the Nonlinear Internal Wave Investigation (NLIWI) from April to July 2007. Maximal effort during this work period focused on writing up the WISE/VANS data for publication, with emphasis on the seasonal climatology of wave occurances. We also collaborated frequently with Oliver Fringer and PhD student Zhonghua Zhang at Stanford to understand the SUNTANS numerical model runs.
