| 摘 要： | 介绍一种用矩不变量跟踪天气雷达回波，以估测回波区域内部流场的方法。研究工作表明：根据回波强度场计算得到的矩不变量能很好地代表回波模块的特征，可用来估算雷达回波区流场。

| Abstract: | A new moment invariant method was presented to evaluate the flow field within weather radar echo. The study result shows that the moment invariants are very useful for extracting the features of modules from radar data and could be applied to the tracking of radar echo to determine the internal movement of the storm. |
