| 摘 要： | 文中利用相平面分析法 ,由非绝热大气运动方程组导出了与非线性重力内波有关的 Kd V方程 ,然后用直接积分法得到两类有意义的孤立波解 ,重点分析了一类具有间断点的奇异孤立波解的特征 ,初步建立了此波解与一类青藏高原暖性低涡的联系 ,讨论了高原加热和层结稳定度对高原低涡生成和移动的影响 ,并且从理论上论证了高原低涡具有与热带气旋类低涡( Tropical cyclone- like vortices)类似的涡眼和暖心结构

| Abstract: | The KdV equation is derived from nonlinear internal inertial gravitational wave equation using phase plane analysis method and two types of solitary wave solutions with weather meaings are obtained by a direct integration method.The characristics of singular solitary wave are specially discussed and the relationship between the vortex over the Tibetan plateau and this solitary wave is established,and the effects of plateau heating and atmospheric stability on the plateau vortex are analyzed.Morever,the features of vortex eye and warm core associated with the plateau vortex similar to tropical cyclone like vortices(TCLV)are proved in theory. |

| Keywords: | Nonlinear Singular solitary wave Tropical cyclone like vortices Plateau vortex Heating |
