A Numerical Investigation of the Potential Effects of Aerosol-Induced Warming and Updraft Width and Slope on Updraft Intensity in Deep Convective Clouds
Publisher: American Meteorological Society
Abstract: AbstractThe effects of aerosol perturbations on deep convective clouds have received considerable attention in the recent literature, especially from a modeling perspective. The published responses in precipitation amount ...
The Sensitivity of a Numerically Simulated Idealized Squall Line to the Vertical Distribution of Aerosols
Publisher: American Meteorological Society
Abstract: hanges in the aerosol number concentration are reflected by changes in raindrop size and number concentration that ultimately affect the strength of cold pools via evaporation. Therefore, aerosol perturbations can potentially ...
A Novel Scheme for Parameterizing Aerosol Processing in Warm Clouds
Publisher: American Meteorological Society
Abstract: novel two-moment bulk aerosol parameterization is derived from a state-of-the-art 2D bin microphysics model using power-law relationships and a semi-analytical technique for activation. The activation scheme predicts both ...
Dynamical Effects of Aerosol Perturbations on Simulated Idealized Squall Lines
Publisher: American Meteorological Society
Abstract: he dynamical effects of increased aerosol loading on the strength and structure of numerically simulated squall lines are explored. Results are explained in the context of Rotunno?Klemp?Weisman (RKW) theory. Changes in ...
A New Perspective on Coastally Trapped Disturbances Using Data from the Satellite Era
Publisher: American Meteorological Society
Abstract: AbstractThe ability of global climate models to simulate accurately marine stratiform clouds continues to challenge the atmospheric science community. These cloud types, which account for a large uncertainty in Earth?s ...
On the Mechanisms of Rain Formation in an Idealized Supercell Storm
Publisher: American Meteorological Society
Abstract: eep convective storms produce raindrops through three mechanisms: condensation and coalescence growth of cloud liquid droplets (i.e., warm processes), melting of ice hydrometeors, and shedding from wet hailstones. To ...
Storms Producing Large Accumulations of Small Hail
Publisher: American Meteorological Society
Abstract: Hail-bearing storms produce substantial socioeconomic impacts each year, yet challenges remain in forecasting the type of hail threat supported by a given environment and in using radar to estimate hail sizes more accurately. ...
The Ice Particle and Aggregate Simulator (IPAS). Part I: Extracting Dimensional Properties of Ice–Ice Aggregates for Microphysical Parameterization
Publisher: American Meteorological Society
Abstract: AbstractAggregation, the process by which two or more ice particles attach to each other, is typically observed in clouds that span a range of temperatures and is influenced by the crystal shape (habit). In this study, the ...
