  • Impacts of Number of Cloud Condensation Nuclei on Two-Dimensional Moist Rayleigh Convection

    MIYAMOTO Yoshiaki , NISHIZAWA Seiya , TOMITA Hirofumi

    湿潤Rayleigh対流に対する雲凝結核の数濃度(CCN)及び他の熱力学変数の影響を調べた。この目的のため、二次元のブジネスク流体に相変化・降水過程を含む一連の雲物理を解く数値モデルを構築した 。実験の結果、CCN数の影響は、計算の最初に出現する対流にのみ現れ、そのあとの準定常状態では影響が少ないことが示された。これは、最初に現れる対流は、パーセル理論のように背景の循環に支配される対流ではなく、一 …
