Effects of Cloud Parameterization on Radiation and Precipitation: A Comparison Between Single-Moment Microphysics and Double-Moment Microphysics

This study compares a single-moment microphysics scheme to a double-moment microphysics scheme using four observed cases of a mesoscale cloud system. Previous studies comparing a single-moment microphysics scheme to a doublemoment microphysics scheme have focused on microphysical processes or overall dynamics, precipitation and morphology of cloud systems. However, they have not focused on how ...

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...

Confronting the Pedagogical Challenge of Cyber Safety

Cyber violence and the antidote of cyber safety are fast becoming a global concern for governments, educational authorities, teachers, parents and children alike. Despite substantial funding for information dissemination on preventative strategies and the development of electronic responses to hinder perpetrators, the phenomenon of cyber violence has received little attention in the educational...

Black carbon radiative heating effects on cloud microphysics and implications for the aerosol indirect effect: 2. Cloud microphysics

This work examines the effect of black carbon (BC) radiative heating on cloud droplet formation. Changes in cloud droplet concentration and cloud albedo due to the presence of black carbon are computed for different cases of aerosol size distributions, meteorological conditions, BC mixing state, and aerosol composition. We examine the effect of three new mechanisms (that result from BC heating)...
