The maximum rainfall events in all prefectures in ningixa occurred in the relative warm and stable clouds , d ) 宁夏各地逐时降水的极大值均产生于较暖的云团或云系中。
When the rainfall reaches 1 mm , the reading from the raingauge with the maximum rainfall in each region will be summarized in the bulletin 当雨量达到一毫米时,每小时天气报告便会提供各区过去一小时内录得的最高雨量。
And a scaling lognomial model of rainfall intensity is introduced to represent the affection of temporal scale of duration in annual maximum rainfall intensity distributions 另外,本文提出了暴雨强度的对数正态分布模型来表征年最大暴雨强度分布中历时的尺度影响。
Potential instability existed near 0 in the warm area and between - 10 and 0 in the cold area . the occurrence of potential instability was corresponding with maximum rainfall and maximum vapor content C附近,冷区位势不稳定分布在一10一ooc ,位势不稳定出现的时间与地面强降水、水汽最大累积区出现的时间一致。
The scaling hypotheses is applied to the relationship of annual maximum rainfall intensity and duration . the rainfall intensity - duration - frequency form is proved based on the temporal scaling property of rainfall 由年最大平均暴雨强度随历时变化的标度性质推导出暴雨公式的形式,找到了暴雨公式的理论根基? ?暴雨在时间上分配具有自相似性的结果。
Heavy rainfall occurred in the warm area , and maximum rainfall lay in the windward slope where the width of raindrop size distribution was b roadened and sometimes it was bimodal spectrum . the shape of rain band in cold area was zonal , and the area of rain band was small 暖区有明显的强降水中心,雨强极大值出现在山区迎风坡,降水雨滴谱谱宽较大,有时滴谱呈双峰型分布;冷区降水区常呈带状分布,雨区范围大,雨滴谱较窄,雨滴谱为单峰型。
