Bulk Convergence of Cloud-Resolving Simulations of Moist Convection over Complex Terrain
Publisher: American Meteorological Society
Abstract: he explicit treatment of moist convection in cloud-resolving models with kilometer-scale horizontal resolution is increasingly used for atmospheric research and numerical weather prediction purposes. However, several ...
Lagrangian Investigation of the Precipitation Efficiency of Convective Clouds
Publisher: American Meteorological Society
Abstract: he precipitation efficiency of cumulus congestus clouds is investigated with a new Lagrangian particle framework for large-eddy simulations. The framework is designed to track particles representative of individual water ...
Mesoscale Impacts of Explicit Numerical Diffusion in a Convection-Permitting Model
Publisher: American Meteorological Society
Abstract: n convection-permitting simulations, the spectrum of resolved motions is truncated near scales where convection is active. An ?energy gap? between resolved and unresolved motions does not exist, such that the upscale and ...
Long-Term Simulations of Thermally Driven Flows and Orographic Convection at Convection-Parameterizing and Cloud-Resolving Resolutions
Publisher: American Meteorological Society
Abstract: he purpose of this paper is to validate the representation of topographic flows and moist convection over the European Alps in a convection-parameterizing simulation (CPM; ?x = 6.6 km) and two cloud-resolving simulations ...
Influence of the Background Wind on the Local Soil Moisture–Precipitation Feedback
Publisher: American Meteorological Society
Abstract: he importance of soil moisture anomalies on airmass convection over semiarid regions has been recognized in several studies. The underlying mechanisms remain partly unclear. An open question is why wetter soils can result ...
