| 摘 要： | For certain particular initial values, the results of numerical weather prediction are extremely sensitive to the errors in some parameters of the models, which probably is one of the reasons to bring about serious failures to the forecast. In this paper, this speculation is shown by an example of numerical experiments, and it is suggested that the parameters in the models be modified with the information provided by observational data of the recent atmospheric evolution to avoid failures of the forecast. The numerical simulation tests with a simple quasi-geostrophic barotropic model have obtained satisfying results.
