Impact of Cloud Microphysics on the Development of Trailing Stratiform Precipitation in a Simulated Squall Line: Comparison of One- and Two-Moment Schemes
TL;DR: A two-moment cloud microphysics scheme predicting the mixing ratios and number concentrations of five species (i.e., cloud droplets, cloud ice, snow, rain, and graupel) has been implemented into the Weather Research and Forecasting model (WRF) as discussed by the authors.

Explicit Forecasts of Winter Precipitation Using an Improved Bulk Microphysics Scheme. Part I: Description and Sensitivity Analysis
TL;DR: In this paper, the authors evaluated the sensitivity of winter precipitation to various aspects of a bulk, mixed-phase microphysical parameterization found in three widely used mesoscale models [the fifth-generation Pennsylvania State University-National Center for Atmospheric Research Mesoscale Model (MM5), the Rapid Update Cycle (RUC), and the Weather Research and Forecast (WRF) model].

Microphysics of Clouds and Precipitation
TL;DR: In this article, the authors focus on one major aspect of cloud microphysics, which involves the processes that lead to the formation of individual cloud and precipitation particles, and provide an account of the major characteristics of atmospheric aerosol particles.

Bulk Parameterization of the Snow Field in a Cloud Model
TL;DR: In this paper, a two-dimensional, time-dependent cloud model was used to simulate a moderate intensity thunderstorm for the High Plains region, where six forms of water substance (water vapor, cloud water, cloud ice, rain, snow and hail) were simulated.

On the distribution and continuity of water substance in atmospheric circulations
TL;DR: In this paper, the conservation and distribution of water substance in atmospheric circulations are considered within a frame of continuity principles, model air flows, and models of microphysical processes, where the simplest considerations of precipitation involve its vertical distribution in an updraft column, where condensate appears immediately as precipitation with uniform terminal fallspeed.

Production of secondary ice particles during the riming process
John Hallett,S. C. Mossop +1 more
TL;DR: In this paper, the concentrations of ice particles in natural clouds and their ability to predict them from measurements made, for example in laboratory cloud chambers, at the same temperature were investigated, and the results showed that ice crystals play a vital part in the formation of precipitation.

New primary ice-nucleation parameterizations in an explicit cloud model
TL;DR: In this paper, a model combining the effects of deposition and condensation-freezing nucleation is formulated based on data obtained from continuous-flow diffusion chambers, which indicate an exponential variation of ice-nuclei concentrations with ice supersaturation reasonably independent of temperatures between −7° and −20°C.
