Lightning simulation is important for a variety of applications, including lightning forecast, atmospheric chemical simulation, and data assimilation. In this study, the potential five storm parameters (graupel volume, precipitation ice mass, radar echo maximum updraft, updraft volume) to be used as proxy diagnosis gridded total flash rates has been investigated in convection-allowing model. A ...

Whereas it is now widely accepted that cumulus cloud sizes are power-law distributed, characteristic exponents reported in the literature vary greatly, generally taking values between 1 and >3. Although these differences might be explained by variations environmental conditions or physical processes organizing ensembles, use of improper fitting methods may also introduce large biases. To addres...

Abstract With the projected expansion of arid/semi‐arid regions in a warming world, precipitation enhancement activities such as cloud seeding will become increasingly popular and relied upon. Due to inherent costs, successful planning is crucial, which involves accurate model predictions. In this study, usefulness Weather Research Forecasting (WRF) forecasts for guidance into operations United...

Abstract. The increase in computing power and recent model developments allow for the use of global kilometer-scale weather climate models routine forecasts. At these scales, deep convective processes can be partially resolved explicitly by dynamics. Next to horizontal resolution, other aspects such as applied numerical methods, hydrostatic approximation, time step size are factors that might i...

To investigate further the characteristics of thunderstorms on Qinghai–Tibet plateau, a plateau vortex (PV) thunderstorm and local thermoconvective (TC) over Nagqu area are analyzed using cloud-radar, microwave-radiometer, raindrop-spectrometer data, their macrophysical microphysical evolution discussed in terms thermodynamic processes, lightning activities. The results show following. 1) cloud...
