On the robustness of aerosol effects on an idealized supercell storm simulated with a cloud system-resolving model [PDF]

open access: yes, 2012
A cloud system-resolving model (the Weather Research and Forecasting model) with 1 km horizontal grid spacing is used to investigate the response of an idealized supercell storm to increased cloud droplet concentrations associated with polluted ...

Correcting Fast-Mode Pressure Errors in Storm-Scale Ensemble Kalman Filter Analyses

open access: yesAdvances in Meteorology, 2013
A typical storm-scale ensemble Kalman filter (EnKF) analysis/forecast system is shown to introduce imbalances into the ensemble posteriors that generate acoustic waves in subsequent integrations.

Impact of a Diagnostic Pressure Equation Constraint on Tornadic Supercell Thunderstorm Forecasts Initialized Using 3DVAR Radar Data Assimilation

open access: yesAdvances in Meteorology, 2013
A diagnostic pressure equation constraint has been incorporated into a storm-scale three-dimensional variational (3DVAR) data assimilation system. This diagnostic pressure equation constraint (DPEC) is aimed to improve dynamic consistency among different
