Abstract: Moist convection is a physical process where the latent heat released by condensation acts as a buoyancy source that can enhance or even trigger an overturning convective instability. Since the saturation temperature often decreases with height, condensation releases latent heat preferentially in regions of upflow. Due to this inhomogeneous heat source, moist convection may be more sensitive to changes in flow morphology, such as those induced by rotation, than dry Rayleigh-B\'enard convection. In order to study the effects of rotation on flows driven by latent heat release, we present a suite of numerical simulations that solve the Rainy-B\'enard equations (Vallis et al. 2019). We identify three morphological regimes: a cellular regime and a plume regime broadly analogous to those found in rotating Rayleigh B\'enard convection, and a novel funnel regime that lacks a clear analog within the regimes exhibited by dry convection. We measure energy fluxes through the system and report rotational scalings of the Reynolds and moist Nusselt numbers. We find that moist static energy transport, as measured by a moist Nusselt number, is significantly enhanced in the funnel regime without a corresponding enhancement in Reynolds number, indicating that this funnel regime produces structures with more favorable correlations between the temperature and vertical velocity.

Abstract: 湿对流是一种物理过程，在这个过程中，凝结释放的潜热作为浮力源可以增强甚至触发翻转的对流不稳定。由于饱和温度通常随高度降低，凝结更倾向于在上升区域释放潜热。由于这种非均匀的热源，湿对流可能比干瑞利-本杰明对流对流动形态的变化更为敏感，比如由旋转引起的那些变化。为了研究旋转对潜热释放驱动的流动的影响，我们展示了一系列数值模拟，这些模拟求解了Rainy-Bénard方程（Vallis等人，2019年）。 我们识别出三种形态：一种类似于旋转瑞利-本杰明对流中的细胞态和羽流态的形态，以及一种在干对流的形态中没有明确类比的新颖漏斗态。 我们测量系统中的能量通量，并报告雷诺数和湿润努塞尔数的旋转缩放关系。 我们发现，以湿润努塞尔数衡量的湿润静态能量传输在漏斗态中显著增强，而雷诺数没有相应增强，这表明这种漏斗态产生了温度和垂直速度之间更加有利的相关结构。
