Large‐Eddy Simulations of a Convection Cloud Chamber: Sensitivity to Bin Microphysics and Advection

Aerosol effects on cloud dynamics , microphysics and precipitation : numerical simulations with WRF with spectral ( bin ) microphysics

Sensitivity of WRF cloud microphysics to simulations of a severe thunderstorm event over Southeast India

In the present study, we have used the Weather Research and Forecasting (WRF) model to simulate the features associated with a severe thunderstorm observed over Gadanki (13.5 N, 79.2 E), over southeast India, on 21 May 2008 and examined its sensitivity to four different microphysical (MP) schemes (Thompson, Lin, WSM6 and Morrison). We have used the WRF model with three nested domains with the i...

The Importance of the Shape of Cloud Droplet Size Distributions in Shallow Cumulus Clouds. Part I: Bin Microphysics Simulations

In this two-part study, the relationships between the width of the cloud droplet size distribution and the microphysical processes and cloud characteristics of nonprecipitating shallow cumulus clouds are investigated using large-eddy simulations. In Part I, simulations are run with a bin microphysics scheme and the relative widths (standard deviation divided by mean diameter) of the simulated c...

The Sensitivity of Simulated Shallow Cumulus Convection and Cold Pools to Microphysics

The sensitivity of nested WRF simulations of precipitating shallow marine cumuli and cold pools to microphysical parameterization is examined. The simulations differ only in their use of two widely used doublemoment rain microphysical schemes: the Thompson andMorrison schemes. Both simulations produce similar mesoscale variability, with the Thompson scheme producing more weak cold pools and the...
