The artificial rainmaking ( cloud seeding ) doesn ' t help much 人造雨(云种散播)没发挥什麽多大的作用。
Investigation on catalyst dosage in aircraft cloud seeding in stratiform clouds 层状云飞机增雨催化剂用量研究
The government is using cloud seeding to try to produce rain for farmers , stave off drought and fill water basins 而且政府经常用人工降雨来为农民制造降雨,对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 尽管如此,一个官方人士承认,人工降雨可以使他们阻止8月8号比较轻量级的降雨,他们是无法阻止一场形成中的大暴雨的。
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,根据河南省近20年的历史资料,分别用以降水量为协变量的ca - fcm方法、以降水量和整层大气可降水量为协变量的ca - fcm方法和浮动对比区历史回归统计检验方法( fcm ) ,对河南省4月和10月增雨作业进行评估。
