| 摘 要： | 通过分析98.6连续暴雨过程的扰动风场与降水强度之间的关系,以及扰动风场与非线性和线性对称不稳定之间的关系,进而研究非线性和线性对称不稳定与降水强度和位置之间的关系,认为在日常降水预报中应注意扰动风场的变化以及非线性和线性对称不稳定。

| 关 键 词： | 扰动风场 对称不稳定 降水强度 降水位置 |

| Abstract: | By analysis the relationship between disturbance wind field and precipitation intensity of "98,6" continuous rainstorm process, and the relationship between disturbance wind field and linear (nonlinear) symmetric instability, furthermore, the relationships between linear (nonlinear) symmetric instability and precipitation intensity and position. It is thought that the change of disturbance wind field and the linear (nonlinear) symmetric instability should be paid more attention during daily precipitation forecast. |

| Keywords: | disturbance wind field symmetric instability precipitation intensity precipitation position |
