An Electric Field Mill in Koganei Campus. 大気電場多点観測

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 laboratory), Lenggoro laboratory has cooperated within the atmospheric electric field multipoint observation network. It is reported that in Tama area 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 electric field which thunder cloud… Continue reading An Electric Field Mill in Koganei Campus. 大気電場多点観測

Does the leaf structure prevent the deposition of airborne particles? 葉の構造は大気中微粒子の付着を防止するのか?

Other "intro" of papers from our lab >> /tag/paper/ Our results suggest that epicuticular wax crystals affect distribution of particles on needles. Densely distributed epicuticular wax crystals might prevent the deposition of sub-micron particles on the surfaces of needles to retain the function of stomata. 電界放出型走査電子顕微鏡(FE-SEM)によるスギ(代表的な針葉樹種)の葉表面に人工的に散布されたサブミクロンサイズの炭素系粒子の局在を調べました。気孔の機能を保持するために、密に分布されたエピクチクラワックス結晶は、気中からの微粒子の付着を防止する役割があるかもしれません。 Elucidation of the mechanism of adsorption of particles suspended in the… Continue reading Does the leaf structure prevent the deposition of airborne particles? 葉の構造は大気中微粒子の付着を防止するのか?
