暴雨

It has been decades of years that the domestic highway is paved with 1.5-to-2.0 centimeter-deep open graded friction course. According to studies on road maintenance, the rain cannot be drained immediately on the border between lower unbent and horizontal gradients, as Taiwan is located at subtropics, and temporary summer showers are frequent in the south. Such a condition often leads to large amounts of water on the road and greatly influences driving safety.

国内高速公路面层铺设开放级配摩擦厚度1.5~2.0cm之经验已有数十年，惟依路面养护搜集资料显示，因台湾地处亚热带，气候为高温多雨，尤其南部路段易於夏季下间歇性暴雨，致於纵向坡度较低及横向坡度变化交界处，雨水无法即时宣泄，易产生积水现象，影响行车安全甚巨。

Flexibleconvenient:It is smalllight,and can be clutched to the beltbe arried by otherparts of body.It also utilizes magnet power to be attracted to the surfce of metal objects,or hangsfixedly on the underprop.

防水性能：外壳防护按IP66设计，可抵抗高压水炮直射、暴雨喷淋和海浪溅射智能保护：灯内配有电池过放，过充及短路保护电路，有效保护电池，延长使用寿命。

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。

The results show that this wide range precipitation produced under the deep warm ad vection condition and lower jet stream provided the water vapororig in for this precipitation.The meso -scale closing echo displayed in ladar echo explained that meso-scale and micro-scale system enhanced and developed un...

结果表明：此次降水是在深厚的暖平流条件下产生的大范围降水，低空急流为此次降水提供了水汽来源；而雷达回波上表现出中尺度弥合回波，说明在局地动力和热力条件下加强发展的中小尺度系统是造成此次暴雨的主要原因。

It reduces damage from heavy rains. And vetiver planted on earthen dams may strengthen them against breaks and flooding.

它减少了来自暴雨的损失，并且在堤坝上种植的香根草可以使它们加强抵御断层和洪水。

Heavy rainfall occurred in the southeast of vortex and shear line.

暴雨发生在低涡切变线的东南侧。

To simulation of weather patterns, the capability of stimulation to 850hPa is not as good as the one to 500hPa, which may be caused by underlying surface. In addition, the capability of stimulation to 48h is also not as good as the one to 36h. By analysis of result of stimulation to heavy rainfall happened on 8 July, 2003, we have found that rain belt location and its heavy rain core amounts in sensitivity run are preferably displayed by MM5V3. Analyses indicate this event was in close relationship with the southwest low vortex moving to east from the Tibetan Plateau and low-level jet in front of vortex and shear line.

模拟结果总体的TS评分、大雨以上准确率及暴雨以上准确率较MAPS模式都普遍更高；在对天气形势场的模拟能力方面，模式对850hPa上天气形势场的模拟效果不如500hPa上的模拟效果好，其可能原因是受下垫面的影响所致，并且总的看来，36小时的模拟效果优于48小时的模拟效果。

The influential systems of irregular airflow pattern are shear line,low vortex and small slot near the east of Qinghai-Xizang plateau, vertical ascending motion is stong,mesoscale feature is obvious. There are two vapor transportation passages,one is warm southwest airflow from Bay of Bengal along the south of Himalayas to Longnan. The airflow from the East China Sea and South Sea meet in south China ,then toward Longnan.

不规则型暴雨主要的影响系统有高原东侧切变、高原低涡和短波槽，垂直上升运动比较强烈，中尺度特征明显；水汽来源主要有两支，一支是从孟加拉湾地区沿高原南侧北上的西南暖湿气流，另一支来自我国东海和南海，在华南汇集后转向，然后北上到陇南地区，有较强的能量锋区和明显的锋生。

The sinking of the high potential vorticity is related to the lower vortex and the rainfall increasing.

北支环流圈的加强以及动量下传使暴雨区北部低层的北风分量维持。

It was several days after the storm before they could repair the washout and open the road.

暴雨后的几天，他们修理冲坏的地方，并开放了公路。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
