Understanding and Prediction of Ocean Mesoscale Variability

Modeling of mesoscale processes in the ocean, for which I was awarded the 2004 Prize of the Oceanographic Society of Japan, is described. The first example is a jet instability, described in my doctoral thesis as a pure fluid dynamics phenomenon. The following studies seem attractive to the oceanographic community: meanders and eddies in the Gulf Stream with foci on baroclinic instability and nonlinear wave-wave interactions. Data assimilation methods, which are necessary in ocean weather forecasting, have been used for reconstructing subsurface fields from surface data. One example of this is a deep velocity field from altimeter data, and another example is looking at total carbonate beneath the summer mixed layer from the annual surface data.
