The influence of entrainment and mixing assumption on aerosol-cloud interactions in marine stratocumulus

This study uses large-eddy simulation with bin microphysics to investigate the in?uence of entrainment and mixing on aerosol–cloud interactions in the context of idealized, nocturnal, nondrizzling marine stratocumulus (Sc). Of particular interest are (i) an evaporation–entrainment effect and a sedimentation–entrainment effect that result from...

A Performance Comparison between Multiphysics and Stochastic Approaches within a North American RAP Ensemble

A stochastic parameter perturbation (SPP) scheme consisting of spatially and temporally varying perturbations of uncertain parameters in the Grell–Freitas convective scheme and the Mellor–Yamada–Nakanishi–Niino planetary boundary scheme was developed within the Rapid Refresh ensemble system based on the Weather Research and Forecasting Model. Al...

An Evaluation of Stochastic Physics Within the High Resolution Rapid Refresh (HRRR) Ensemble and the Impacts of High Performance Computing (HPC)

Lack of spread is a common deficiency in ensemble models and results in over-confident and inaccurate forecasts. A number of options exist to increase the spread of an ensemble, including the use of multiple physics parameterizations or dynamic cores. However, implementation of these options can be cumbersome, costly, and suffer from certain t...

Rapid Mesoscale Environmental Changes Accompanying Genesis of an Unusual Tornado

This study documents a very rapid increase in convective instability, vertical wind shear, and mesoscale forcing leading to the formation of a highly unusual tornado as detected by a ground-based microwave radiometer and wind profiler, and in 1-km resolution mesoanalyses. Mesoscale forcing for the rapid development of severe convection began wit...

Real-Time Applications of the Variational Version of the Local Analysis and Prediction System (vLAPS)

The accurate and timely depiction of the state of the atmosphere on multiple scales is critical to enhance forecaster situational awareness and to initialize very short-range numerical forecasts in support of nowcasting activities. The Local Analysis and Prediction System (LAPS) of the Earth System Research Laboratory (ESRL)/Global Systems Divis...
