PROBLEM TO BE SOLVED: To provide an artificial rainfall nozzle with which various shapes of artificial rainfall areas are attained and an area of the artificial rainfall can be easily enlarged, and to provide an artificial rainfall device.SOLUTION: An artificial rainfall nozzle 10 used when bringing rain artificially is constructed including a flexible tube part 13C that is connected with a water supply source, formed of a flexible member, and includes a tip opening part 13F from which water is gushed out. A piece of flap-like chip 13E is arranged at the tip opening part 13F of the flexible tube part 13C as turbulence generation means T G in which turbulence of water containing a pulsatile flow is generated from a laminar flow state.COPYRIGHT: (C)2015,JPO&INPIT【課題】人工降雨エリアの多様な形状を得ると共に人工降雨の面積拡大を容易にすることを可能とした人工降雨用ノズルおよび人工降雨用装置を提供する。【解決手段】人工的に雨を降らせる際に使用される人工降雨用ノズル10を、水供給源に接続され可撓性部材で形成されると共に外部に向けて水を噴出する先端開口部13Fを有するフレキシブルチューブ部13Cを備えた構成とし、フレキシブルチューブ部13Cの先端開口部13Fに、水が層流状態から脈動流を含む乱流を発生させる乱流発生手段T・Gとして、1枚のフラップ状片13Eを設けて構成した。【選択図】図2
