The flow and condensation of supersonic steam jet submerged in the quiescent subcooled water were investigated experimentally at first. 首次針對超音速蒸汽在過(guò)冷水中浸沒(méi)射流流動(dòng)與凝結換熱特性進(jìn)行了系統的實(shí)驗研究。
AgI-seeding should be done before the activation of most ice nuclei start, so as to enhance rainfall through increasing ice crystals content, and deleting super-cooled cloud water. 結果表明,該地區秋季對流云降水主要為冷云降水,冰晶是霰產(chǎn)生的主要來(lái)源,冰霰自動(dòng)轉化是霰產(chǎn)生的最主要方式,冰晶與霰的碰并又促進(jìn)了霰的進(jìn)一步增長(cháng),霰是云中過(guò)冷水消耗的主要因素。
