The adjoint problem and sensitivity algorithms for the model of atmospheric hydrodynamics in σ–coordinates

Variational statement of the hydrodynamical atmospheric problem in σ-coordinates is considered. The system of the adjoint equations and algorithms for the sensitivity investigation of the numerical model to the variations of input parameters are constructed. The example of the system organization of the direct and adjoint problems and the schemes of their realization for the typical combination of time approximations are given.
