伴随模式越来越多地应用于气象学和海洋学中的许多问题。MM 5的伴随模型是一种有效计算任何MM 5预测方面相对于模型控制变量的梯度（或盖特奥导数）的工具，该控制变量包括模型初始条件、边界条件和定义物理和数值条件的模型参数。积分的条件。简要回顾了伴随模式在气象学中的不同应用，并给出了它们的数学公式，说明了伴随模式和/或切线性模式在每种应用中的应用。然后，作者描述的数学和数值公式用于开发伴随版本的MM 5。
Adjoint models are increasingly applied to many problems in meteorology and oceanography. The adjoint model of MM5 is a tool which effectively computes the gradient (or a Gateau-derivative) of any MM5 forecast aspect with respect to the model's control variables, which consist of model initial conditions, boundary conditions, and model parameters that define the physical and numerical conditions of the integration. Different applications of adjoint models in meteorology are briefly reviewed and their mathematical formulae are provided which illustrate how the adjoint model and/or tangent linear model are used in each application. Then the authors describe the mathematical and numerical formulation used in developing the adjoint version of MM5.
