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，根據河南省近20年的歷史資料，分別用以降水量為協變量的ca - fcm方法、以降水量和整層大氣可降水量為協變量的ca - fcm方法和浮動對比區歷史回歸統計檢驗方法（ fcm ） ，對河南省4月和10月增雨作業進行評估。 -
Then, six evaluation methods ( double ratio analysis evaluation method using regional rainfall tendency control for single cloud seeding operation case, regression analysis evaluation effects on the bases of regional correlation and developing tendency of rainfall, multiple regression analysis evaluation effects on the bases of regional developing tendency of rainfall, 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 used as meteorological covariate, and float ing control historical regression method ) were compared and analyzed with the case of the cloud seeding operation on 5 april 2002 in henan province
然後，以河南省2002年4月5日飛機增雨作業為個例，對作業區域趨勢對比雙比分析評估方案、區域趨勢相關回歸分析方案、區域趨勢多元回歸分析方案、以降水量為協變量的ca - fcm方法、以降水量和整層大氣可降水量為協變量的ca - fcm方法和fcm方法6種評價方案進行分析比較。 -
In the end, cluster - analysis - based floating control historical regression method with uniform precipitation and atmospheric precipitable water as metoorological covariates could more validly evaluate efficiency of cloud seeding operations and significant level of ca - fcm method was higher than the other methods, because it adopted cluster analysis which highly improved the correlativity between rainfall distributions in the control area and target area, and used grid interpolation which enhanced exactness of calculating precipitation rainfall, and chose atmospheric precipitable water as the covariant which increased the inferential accuracy of natural rainfall on the cloud seeding operational area
最後，得到以降水量和整層大氣可降水量為協變量的ca - fcm方法，由於採用聚類分析（ ca ）方法，提高了對比區和影響區相關性；採用網格插值技術提高了雨量的計算準確度；引入了不受催化影響的物理協變量（整層大氣可降水量） ，提高了作業區自然降水量估計值的準確性；所以評估效果最好，顯著水平高於0 . 05 。 -
