Effect of Inverted Trough on Heavy Rainfall Process of Handan

采用统计分型，分别找出低槽型、切变线型、台风倒槽型暴雨的24h预报指标。

After careful statistic , we have classified the rainstorms into three types - the low trough , shear line and Typhoon inverted trough and the forecast indexes have also been got .

同时，用非地转湿Q矢量分析方法诊断了由北上台风倒槽引起的一次华北特大暴雨过程；

At the same time , the non geostrophic wet Q vector was applied to diagnose a torrential rain process in North of China .

与锋面伴随的850hPa冷槽型、暖式切变型和冷式切变型，酸雨出现率大，倒槽型最小。

The frequency is large with the types of cold troughs , warm shears and cold shears but small in the type of inverted troughs .

导致本次过程降雪产生的主要影响系统是地面倒槽和700hPa中α尺度低涡，其影响时间相对持久。

The main effect system of causing snowstorm process is surface inverse trough and 700 hPa meso - α - scale low vortex , and its impact time is relative to the lasting .

地面强辐合区随着倒槽发展向偏北方向伸展；

A strong convergent region extended northward accompanied the surface inverted trough .

低层螺旋度大值中心轴线与切变线和地面倒槽辐合线走向一致，高层螺旋度与高空急流有关。

The axes of low-layer helicity plus center is concurrent with shear line and the convergence line of surface inversion trough .

1低涡切变线、西南风低空急流、东风气流和地面倒槽是本次暴雨的主要影响系统，该地区维持高能，饱和，位势不稳定的小环境，有利于特大暴雨的产生和维持。

The following conclusions can be drawn . 1 . The main influence systems of causing this heavy rainfall are southwest vortex , shear line and southwest low-level jet .

结果表明，本次大暴雨是由在广东登陆的热带气旋倒槽北伸与西风带弱冷空气相结合的产物。

The results show that the heavy storm was caused by the interaction between a tropical cyclone trough that landed in Guangdong Province and a weak cool front in the westerlies .

根据影响的天气系统，将温州地区的降水性质分为冷空气、倒槽、西南低涡、静止锋、台风、副高边缘对流等典型降水类型。

According to the weather system the rain of Wenzhou are classified into cold air , inverse trough , southwest low vortex , Mei-Yu , typhoon , convection on edge of subtropical anticyclone .

倒槽、副高后部、台风低压、高空低涡类和气旋类等系统最强，日降雨量和单位面积降雨量明显比其它系统大，尤其对蓄水型火箭增雨作业十分有利。

The converse trough , typhoon low-pressure , upper-level low vortex and cyclones are the suitable weather systems for rocket precipitation enhancement with greater rainfall amount . The subtropical high moved northward and westward .

The heavy fogs of Shangqiu are formed by the weather situations : continental anticyclone , warm zone in front of cold front , uniform pressure field , and low pressure with an inverted trough .

2003年11月6日大同市产生暴雪天气过程，此次暴雪主要是由高空强冷气旋、低气切变线和地面倒槽前部强盛的偏东暖湿气流的共同影响所引发的。

A heavy snow process was taken place on November 6th 2003 in Datong , this snow was arised by the influence of upper strong cold cyclone , low shear line and strong worm humid stream ahead of ground inverse trough .

三种预报产品对低压或倒槽型的降水预报准确率普遍较高；当三种预报产品均预报有降水时，其出现降水的准确率为75.9%。

The accurate rate of rainfall prediction of the three prediction products to the low pressure and upside down trough is commonly higher , and the accuracy of rainfall is 75 9 % when the three prediction products all predict that there will be rainfall .
