中文摘要：
这份报纸测试在与奔流的雨联系的异例由使用第五产生的 NCAR / 佩恩状态 Mesoscale 模型(MM5 ) 输出的好模型模拟数据由台风 No.9914 (丹) 引起了的潮湿的潜在的涡度(MPV ) 上强迫的导致云的质量的影响。诊断结果证明积极 MPV 异例区域，它被从 600 hPa 集成 MPV 到 300 hPa 在获得垂直，粗略地在位置或在分发模式在他们的同步阶段与 降水与一致，并且丹的最大的积极 MPV 区域主要在 600 hPa 和 300 hPa 之间被定位，它比奔流的雨盒子高得多。进一步的分析也证明积极 MPV 异例的值与丹的开发增加了或减少，并且积极 MPV 异例可以也作为 tracer 被服务显示热带气旋紧张的进化。
英文摘要：
This paper tests the impacts of cloud-induced mass forcing on the moist potential vorticity （MPV） anomaly associated with torrential rains caused by Typhoon No.9914 （Dan） by using fine model simulation data outputted by the Fifth-Generation NCAR / Penn State Mesoscale Model （MMS）. The diagnostic results show that the positive MPV anomaly region, which is obtained by integrating the MPV from 600 hPa to 300 hPa in the vertical, roughly coincides with the precipitation at their synchronous stages either in position or in the distribution pattem, and the maximum positive MPV area of Dan is located mainly between 600 hPa and 300 hPa, which is much higher than torrential rain cases. Further analyses also showed that the value of positive MPV anomaly increased or decreased with the development of Dan, and the positive MPV anomaly may also be served as a tracer to indicate the evolution of tropical cyclone intensity.
