摘要 本文概述了变分同化伴随方程理论研究的重要性,讨论了变分同化原理、证明了预报模式方程的伴随方程解的特性;提出了建立伴随方程的分解技术,通过二维浅水波方程的伴随方程的建立,研究了建立伴随方程的数学方法。 This paper describes the importance of performing theoretical studies of the adjoint equation. We discuss the variational assimilation principle,and prove the characteristics of the adjoint equation. We put forward a decomposing technology of creating the adjoint equation. By creating the 2-D shallow-water equation, we study the mathematical method of creating the adjoint equation.
