Evaluating uncertainty in convective cloud microphysics using statistical emulation

Sensitivity experiments of the optical properties of convective systems using a double moment cloud microphysics scheme

Atmospheric Electricity and Cloud Microphysics

The terrestrial atmospheric electrical system covers a range of dimensional scales, from charged molecular clusters to convective cloud systems. Charge-exchange associated with thunderclouds leads to positive charge in the upper conductive regions of the atmosphere and a net negative charge on the planetary surface. In non-thunderstorm regions, a vertical ionic current flows, replenishing the a...

Cloud Microphysics Retrieval Using S-Band Dual-Polarization Radar Measurements

The recent deployment of multiparameter, polarimetric radars provides the impetus for development of microphysical retrievals. The primary objective of this paper is to describe a particle classification technique that makes use of polarimetric radar observations. The particle classification technique is computationally simple enough to be implemented for real-time research and operational fiel...

numerical study of convective cloud development using explicit time-dependent tilting cloud model (ettm)

cumulus parameterization in numerical weather prediction models can significantly affect severe weather forecasts, such as hurricanes, flash floods, and winter storms. the role of convection is essential in stabilizing an unstable atmosphere through vertically transferring moisture, energy, chemical species and momentum. cumulus parameterization schemes use simple one-dimensional convective clo...

Cloud Radiative Heating Rate Forcing Using Profiles of Retrieved Arctic Cloud Microphysics

Clouds and their radiative impacts are of primary importance to the Arctic climate and, therefore, global climate. Clouds dominate the radiation balance within the cold, dry Arctic atmosphere, and cloudradiation feedbacks are closely linked with the snow/ice-albedo feedback. Despite the importance of clouds in the Arctic, our current understanding of these clouds remains limited. Global climate...
