Abstract

A new method is developed as a solution for ill-posedness problem in inversion of open boundary conditions (OBCs). In this method, open boundary curves are parameterized by interpolating values at some selected independent points(IPs) with the Spline. Compared with the linear interpolation traditionally used in OBCs inversion, curves obtained with the new method is more smooth and more consistent with the ocean reality. The model and the method are evaluated in twin experiment(TE).In practical experiment(PE), the T/P satellite observations are assimilated to simulate tides in the Bohai and Yellow Seas(BYS). Mean absolute errors (MAEs) of practical experiment with the new method are smaller than those with the traditional.
