查询词典 rainfall

Convection rain is the most common type of rainfall.

最常见的雨是对流雨。

Based on the radar dense data of convectional cloud on June 12,2004 in Yongdeng county,choosing two similar convectional clouds as seeding and non-seeding cloud,the remarkable changes of radar echo parameters of the seeding cloud compared with the non-seeding cloud were discussed in this paper,and the rain enhancement effect was evaluated primarily with ground observational rainfall data.The results show that many aspects of the seeding cloud,such as precipitation,life characteristic and vertical characteri...

利用2004年6月12日甘肃省永登县雷达观测对流云的加密资料，选取了2次相似对流云过程分别作为目标云和对比云，探讨了目标云作业前后较对比云雷达回波有关参数的显著变化，并结合地面雨量点观测资料对地面人工增雨作业效果进行了初步分析，结果表明：目标云在降水、生命期特征、回波垂直特征参数变化方面，表现出作业前后较对比云存在明显差异，目标云作业40 m in后地面产生0.6 mm降水，而对比云则从新生发展到减弱消散阶段经历较短的时间(30 m in)，地面并无降水产生，从而推断本次人工增雨达到了一定的预计效果。

The minimum potential region of water vapor transport vector correspond to intense heavy rainfall region, and the water vapor convergence of the heavy rain region is supplied by the hemisphere scale water vapor transport, indicating that even for a regional severe flood it must gain water vapor supply from very extensive regions.

水汽通量的势函数极小值区对应强降水区，并且暴雨区的水汽辐合是由半球尺度的水汽输送造成，这表明，即使对于该年背景的区域性大暴雨/洪水，它也必须从极大范围地区获得水汽供应。1999年水汽辐合的中心位置较1998年偏东偏南，这使得1999年降水较1998年偏南。

Especially, the cross correlation analysis was applied to estimate the influence of monthly rainfall days on PM10 monthly average concentration.

分析结果表明：厦门市PMl0浓度年内变化无明显的上升和下降的趋势，但有显著的周期性，分别为3、7和29天，气候因素对PM10浓度的变化有显著的影响。

Some results are gained.(1) There is close relation between the change of south Asia high character index, trough in the westerlies and plum rain date character (the beginning, ending dates and lasting days of plum rain, rainfall and area of rain).

得出：(1)南亚高压特征指数变化和西风槽移动与江苏梅期（入梅、出梅、梅期、梅雨量和落区）特征有密切关系。

In-room tubs for personal spa treatments,"rainfall" showers with Acqua di Parma bath accessories and Duxiana Mattresses and comfortable daybed seating are among the other unique touches.

在室风姿个人疗，"降雨"淋浴acquadi帕尔马浴配件及duxiana床垫和床舒适的座位等其他独特激动。

The effect of colluviums thickness on the rainfall duration required for the initiation and the infiltration depth of soaking line is insignificant.

崩积层之厚度对浸润线形成所需之降雨延时及向下之扩散深度影响不大，但对浸润线与地下水水位线之结合有迟滞之作用。

Single observation tests show that this algorithm can adjust the vertical background structure of the moisture convergence depending on the difference between the observation operator calculation and the TRMM (Tropical Rainfall Measuring Mission) rain rate.

单点试验表明该方案通过调整背景场的水汽辐合和辐散的垂直结构，使得同化后观测算子计算的降水率更接近实况。

The impact of forest on precipitation and relationship between forest and annual rainfall have long been two disputable issues.

森林对降水的影响，森林与流域年径流总量的关系是两个长期以来一直存有争议的问题。

About 70% of the total rainfall as heavy downpour in the summer monsoon months and 30% in winter.

夏季季风季节的暴雨占总降雨量的70%，冬季占30%。
