Abstract

It has been demonstrated for the finite-difference ocean circulation model that the problem of uncertain forcing and input data can be tackled with an optimization techniques. The uncertainty problem in interesting flow properties is exploring a finite difference ocean circulation model due to the uncertainty in the driving boundary conditions. The mathematical procedure is based upon optimization method by the conjugate gradient method using the simulated data and a simple barotropic model. An example for the ocean circulation model is discussed in which wind forcing and the steady-state circulation are determined from a simulated stream function.

최적해(optimal solution)를 구하는 최적화기법이 정방해양의 해수순환을 기술하는 간단한 유한차분모델에 대한 부정확한 외력 및 입력 자료 문제에 적용되어짐을 보였다. 수학적 절차는 추정된 자료 및 간단한 순압성 해수순환모델(wind-driven ocean circulation model)을 이용하여 공액경사법에 의한 최적화 방법에 기초하였다. 해는 부정확성 작용에 제약조건을 적용한 목적함수(objective function)를 최적화함으로써 발견되어지며, 이에 대한 부가제약조건(additional constraints) 수의 영향을 살펴보았다.
