Recently I focus on three research topics:
One is the small-scale shear instability and the subsequent mixing processes in the thermocline of the equatorial Pacific Ocean. We have been conducting regular (yearly) turbulence observations in the western and central equatorial Pacific since 2017, and done a lot of data analysis on the eastern equatorial Pacific based on TAO (Tropical Atmosphere and Ocean) measurements.
The second is the mechanisms for the different type of mesoscale eddies and for the eddy-induced anisotropic lateral mixings as well.
Based on the studies of the above two topics, we aim to improve the existing or construct new mixing parameterizations on both small and meso- scales; we have numerical modes to test the parameterizations.
The third topic is the application of the 4D-VAR (adjoint) data assimilation method in ocean state estimate, ocean parameter optimization and adjoint sensitivity researches. This method enables us to obtain spatial and temporal variations of the ocean parameters (e.g., mixing coefficients), overcoming the lack of direct measurements. It also helps to determine the optimal observational locations. We built an ocean state estimate focusing on the tropical Indian-Pacific Oceans, named as TOOSSE (Two Oceans One Sea State Estimate).
