大気電場多点観測 (2016) Koganei campus: An Electric Field Mill
学芸大学（鴨川研究室）の主催で、レンゴロ研究室は大気電場多点観測ネットワークに協力することになりました。研究の目的としては、多摩地区では落雷や降雹、ゲリラ豪雨を伴った積乱雲が数多く発生することが報告されています。これらの現象は雷雲が作り出す電場の変動と密接な関係があると考えられ、レーダー観測と合わせることで雷雲の電気的な構造を明らかにしていきます。大気電場測定装置を小金井を中心とした半径5km以内の領域に集中展開します。他の設置場所候補として、JAXA筑波宇宙センター、調布航空宇宙センター、調布飛行場があります。 Organized by Gakugei University (Kamogawa Lab.), Lenggoro Lab. has cooperated within the atmospheric electric field multipoint observation network. It is reported that in Tama area (around Koganei city) many thunder clouds accompanied by lightning strikes, hail, and “quick” heavy rain are generated. These phenomena are thought to be closely related to the fluctuation of…
