——由于炎热的天气导致大量的水蒸发到大气中,形成暴雨云,从1958年至今,东北部大暴雨的强度已经增加了67%。
The heaviest rainstorms have already become 67 percent heavier since 1958 in the Northeast, as warmer weather evaporates more water vapor into the atmosphere to feed storm clouds.
由对数值模拟与试验的结果分析得出:(1)青藏高原地形有利于高原东麓暴雨区的扩大与强度加大。
Some results are obtained as follows: (1) The heavy rain area is expanded and heavy rain is enhanced by plateau terrain in the east of plateau.
分析结果表明:这场暴雨具有强度大、面积广和降水时间集中等特点。
The results show that the torrential rain is characterized by high intensity, large areas and concentrative precipitation time.
通过对物源特征和降雨强度对矿渣型泥石流影响的分析,得出研究区矿渣型泥石流主要为暴雨型水石流。
Through the analysis on debris source characteristic and the rainfall intensity's influences, obtains the mine waste debris flow in the research area is rainstorm water-stone flow.
低层水汽输送,造成中纬度暴雨区强水汽辐合和不稳定能量积聚,故槽前降雨的强度与其南方台风东侧的水汽输送有着相当密切的关系。
The results show that typhoon intensity can have influence on the water vapor transport to mid-latitude area by the southeasterly jet on the east of the typhoon.
改进了热带气旋暴雨的落区及降水强度,且主要落区误差的修正位于热带气旋移动路径的右侧并同主要的SST降温区相关;
The distribution and intensity of mesoscale rainfall are improved, with main distribution correction lying on the right of cyclone track and correlating with SST dropping area.
结果表明:WRF模式较好地再现了此次暴雨天气过程,在暴雨落区和强度量级上接近实况。
The results illustrate that:The WRF model is potential in simulating and predicting this precipitation process, including the rainfall area and intensity.
暴雨过程中雨水的入渗导致土体饱和度增加、吸力锐减并引起抗剪强度大幅下降。
Infiltration of rainwater during heavy rain increased soil saturation, sharp dropped in suction and caused a substantial decline in shear strength.
结果表明:(1)MM 5模式准确地预报出盆地西北部大暴雨过程,在降水的中心强度和位置预报上非常接近实况。
The results show that MM5 can forecast the heavy rain process in Northwest Sichuan Basin, the centre intensity and location of the forecast precipitation are close to the observation.
对预报出现的每一场暴雨,确切地说,无论在规模和强度上,这两个方面往往让预期落空。
For every storm that appeared right on cue, at the size and intensity that was predicted, there were two that defied expectations.
在自然条件下,降雨集中、强度大、历时短、暴雨中心靠近流域出口,洪峰流量就会比较大,反之则小,但在人类活动影响下则不一定产生这样的结果。
Runoff yield and flood peak are larger when the rain center is near the outlet of watershed under the natural environment, but it is not necessarily under the human activities environment.
此次暴雨历时短、强度大,但发生前影响系统较弱,有一定的预报难度。
The duration of the rainstorm was shorter with greater intensity. But there were some forecast difficulties because of the weak influence system before the rainstorm.
