| 摘 要： | 利用动力学分析中的相平面方法,由z坐标系下的非绝热大气运动方程组导出了与非线性惯性重力内波有关的KdV方程,然后利用直接积分法得到两类有天气意义的孤立波解.初步建立了孤立波解与高原低涡的联系,进一步从理论上论证了高原低涡具有与热带气旋类低涡类似的涡眼和暖心结构的特征.

| Abstract: | The KdV equation is derived from the z coordinates of the nonlinear inertial gravitational wave equation by the phase plane analysis. Two types of solitary wave solutions with weather meanings are obtained by the direct integration. The singular solitary wave associated wit the Tibetan Plateau vortex is discussed. The low vortex over the Tibetan Plateau has the similar structure of tropical cyclone-like vortex (TCLV) such as vortex eye and warm core. |
