| Abstract: |
| The damping and compressing techniques of sound waves in nonhydyostatic atmospheric numerical model are introduced in this paper. Results of analysis and simulated tests show that the damping and compressing of the sound wave can weaken the solution of the model, and is benefical to computational stability of the model and saves CPU times. |
| Key words: Nonhydrostatic atmospheric model Damping of the sound wave Compressing of the sound wave |
