Investigation on catalyst dosage in aircraft cloud seeding in stratiform clouds 層狀云飛機(jī)增雨催化劑用量研究
The government is using cloud seeding to try to produce rain for farmers , stave off drought and fill water basins 而且政府經(jīng)常用人工降雨來為農(nóng)民制造降雨,對抗干旱并且填充水流域。
However , one official admits that although cloud seeding could be effective in preventing light rain on aug . 8 , it could not curb the onset of a moderate to heavy storm 盡管如此,一個官方人士承認(rèn),人工降雨可以使他們阻止8月8號比較輕量級的降雨,他們是無法阻止一場形成中的大暴雨的。
First , based on the historical data of 20 years of henan province , the cloud seeding operation cases in april and october in the central region of henan province were evaluated by cluster - analysis - based floating control historical regression method with uniform precipitation and atmospheric precipitable water as meteorological covariates , cluster - analysis - based floating control historical regression method with uniform precipitation as meteorological covariate , and floating control historical regression method ( fcm ) 首先,根據(jù)河南省近20年的歷史資料,分別用以降水量為協(xié)變量的ca - fcm方法、以降水量和整層大氣可降水量為協(xié)變量的ca - fcm方法和浮動對比區(qū)歷史回歸統(tǒng)計檢驗方法( fcm ) ,對河南省4月和10月增雨作業(yè)進(jìn)行評估。
