the gravity wave

The distribution of typhoon precipitation presents the positive ad negative change as the gravity wave column wise under the influence of terrain.

台风降水受地形影响呈现出类重力波列式的正负相间的变化分布。

Orographic static data needed in the gravity wave drag physics are recomputed and validated through comparing with the original static data from the ECMWF model.

重新计算了地形重力波过程需要的地形静态资料数据，并与原ecm WF模式的地形静态参数进行了对比分析，验证了模式地形参数的正确性。

The gravity wave analysis contributes to our understanding of the heavy rain process in the region, and improves prediction ability of the Tibetan Plateau area precipitation.

重力波的分析有助于对该地区强降水过程的理解，进而提高青藏高原地区降水的预报能力。
