Abstract: he relative importance, for cloud-top entrainment, of the cooling rates due to longwave radiation, evaporation, and mixing was assessed through analysis of the results produced by a Lagrangian parcel-tracking model (LPTM) ...

Abstract: Cloud-top entrainment instability (CTEI) is a hypothesized positive feedback between cloud-top entrainment and enhanced turbulence associated with buoyancy reversal. A sufficiently strong positive feedback is hypothesized ...

Abstract: In 2001, the authors presented a higher-order mass-flux model called ?assumed distributions with higher-order closure? (ADHOC 1), which represents the large eddies of the planetary boundary layer (PBL) in terms of an assumed ...

Abstract: umerically modeled turbulence simulated by the Advanced Research Weather Research and Forecasting Model (ARW) is evaluated with turbulence measurements from NOAA?s high-resolution Doppler lidar on the NOAA Research Vessel ...

Abstract: Although small-scale turbulent mixing at cloud edge has substantial effects on the microphysics of clouds, most models do not represent these processes explicitly, or parameterize them rather crudely. This study presents ...

Abstract: umerical diffusion can be minimized using fine grid spacing and/or higher-order numerical schemes. In this study, the authors focus on higher-order scalar advection schemes and their effects on simulated cloud fields. A ...

Abstract: n this study, a series of idealized large-eddy simulations is used to understand the relative impact of cloud-top and subcloud-layer sources of moisture on the microphysical?radiative?dynamical feedbacks in an Arctic ...
