辐合

The integrated risk between hydraulic, hydrologic uncertainty and the construction scheduling uncertainty should be analyzed. The paper puts forward the risk analysis model for the construction scheduling and the risk analysis model for construction diversion on the assumption that the construction scheduling is affirmable. Thus the Monte-Carlo method is used to simulate the integrated risk of construction diversion system considering hydraulic, hydrologic uncertainty and the construction scheduling uncertainty.

以风险分析为核心，将各种不确定性因素辐合起来研究施工导流系统的综合风险，提出施工进度计划风险分析模型和假定坝体施工进度确定条件下的施工导流风险分析模型，在此基础上，建立基于Monte-Carlo方法全面考虑水文水力不确定性以及施工进度不确定性的施工导流系统综合风险分析模型。

The warm and wet air before an eastward upper trough from Hexi creep up on the Wedge of cold air, and produce the heavy rainfall.

在暖湿空气势力较强的前提下，在回流冷空气与暖湿气流相遇的辐合带中激发出中尺度系统。

The intensifying high-level anticyclone enhances the pumping effect, which strengthens convergence of air and rainstorm.

3高层反气旋的增强，加强了高空的抽气效应，使辐合上升加强，暴雨增幅。

It is found that the convergence and divergence field of the South Asia High and the northwesterly upper-level jet form a couple of mesoscale direct circulation and counter-circulation.

分析发现，西北风高空急流与南亚高压环流形成的辐散辐合场导致一对中尺度正反环流的生成，使暴雨得以维持与加强。

The allocation of lower level convergence and upper level divergence was favorable to the maintenance of strong updrafts , and the moisture and energy carried by the updrafts was in turn favorable to the genesis and development of convective cloud cluster .

(2)低层辐合，高层辐散的高低空配置有利于强上升运动的维持，强上升气流所携带的水汽和能量有利于对流云团的发生发展，有利于暴雨的维持。

Under the affecting of longitudinal and latitudinal wind stress together, longitudinal wind stress of zero class that is symmetrical to equator has no effects on equations. Nevertheless, longitudinal wind stress of one class that is dissymmetric to equator changes the result and makes longitudinal flow not equal to zero.

在经向风应力和纬向风应力的联合驱动下海洋会有不同的响应，零阶的经向风应力也即对赤道对称的经向风应力没有影响到最后结果，而只有一阶的经向风应力也即对赤道反对称的经向风应力，或者说具有辐合辐散的经向风应力对最后的速度场和位势场造成影响，而且一阶经向速度也不再为零。

It is shown that GPS/PWV data with an time interval of 30 minutes reflected spatial and temporal changes of atmospheric vapor intuitionally and duly, the features of GPS/PWV changes had corresponding relations with the precipitation, the divergence of GPS/PWV showed the distributions of the convergence and divergence of atmospheric vapor.

分析还表明：每30min一次的GPS/Pwv资料能直观地、及时地反映大气中水汽的时间变化和空间变化；GPS/Pwv资料随时间的演变特征与降水有较好的对应关系；GPS/Pwv的散度资料可以反映大气中水汽的辐合、辐散分布情况。

The low-pressure trough of fronts at surface moved southward,and surface pressure fell rapidly,So it caused strong convergence and rising monton.

200hPa辐散，850hPa辐合的垂直配置，有利于低层水汽能源源不断上送；④特大暴雨发生在正涡度中心附近和上升运动中心的南侧。

Following the above conditions,anomalous southerlies transport water vapor to the north and cause moreprecipitation over there.The key condition for the above-normal production year is that SST anomalies over the northwesternportion are warmer than that over the southeastern portion during the winter season.

在此南北分布状态下，风场与辐散风距平均由南向北吹，不仅降低北区冬季东北季风强度，亦将热带水汽往北传送，让北方海域之大气总含水量增加，藉由辐合距平之举升机制，降水量亦随之增加，而水汽递出之南方海域则是二者皆减少。

Basing on the Doppler reflectivity map, the entire precipitation rain bands were apparent westward rotation process. And basing on Doppler radial velocity map, the configuration of low-level convergence with high-level divergence is conducive to the precipitation occurrence and development. The rainstorm resulted from the cloud band maintaining over the rainfall zone.

从多普勒反射率因子图上，整个降水雨带为明显的旋转西进过程；多普勒径向速度图上，低层辐合高层辐散的配置有利于降水的发生发展，暴雨是长时间维持在其上空的强降雨云带造成的。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
