The maximum rainfall events in all prefectures in ningixa occurred in the relative warm and stable clouds , d ) 寧夏各地逐時(shí)降水的極大值均產(chǎn)生于較暖的云團(tuán)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 當(dāng)雨量達(dá)到一毫米時(shí),每小時(shí)天氣報(bào)告便會(huì)提供各區(qū)過(guò)去一小時(shí)內(nèi)錄得的最高雨量。
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,本文提出了暴雨強(qiáng)度的對(duì)數(shù)正態(tài)分布模型來(lái)表征年最大暴雨強(qiáng)度分布中歷時(shí)的尺度影響。
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,冷區(qū)位勢(shì)不穩(wěn)定分布在一10一ooc ,位勢(shì)不穩(wěn)定出現(xiàn)的時(shí)間與地面強(qiáng)降水、水汽最大累積區(qū)出現(xiàn)的時(shí)間一致。
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 由年最大平均暴雨強(qiáng)度隨歷時(shí)變化的標(biāo)度性質(zhì)推導(dǎo)出暴雨公式的形式,找到了暴雨公式的理論根基? ?暴雨在時(shí)間上分配具有自相似性的結(jié)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 暖區(qū)有明顯的強(qiáng)降水中心,雨強(qiáng)極大值出現(xiàn)在山區(qū)迎風(fēng)坡,降水雨滴譜譜寬較大,有時(shí)滴譜呈雙峰型分布;冷區(qū)降水區(qū)常呈帶狀分布,雨區(qū)范圍大,雨滴譜較窄,雨滴譜為單峰型。
