Development of the COAMPS Adjoint Modeling System and Its Application to Storm Initialization Using SSM/I Observations.

摘要

Our long-term goal is to develop a 4-dimensional variational data assimilation system using COAMPS (Coupled Ocean/Atmosphere Mesoscale Prediction System), which could be used for many applications in mesoscale numerical weather prediction. The system can be used to assess the impact of remote-sensing observations on mesoscale and storm-scale prediction. The benefit of using 4D-Var than 3D-Var can also be tested. If computing power is increased, the system can potentially be used operationally at ONR.
