Simulation of Effects of Atmospheric Aerosols on Deep Turbulent Convective Clouds Using a Spectral Microphysics Mixed-Phase Cumulus Cloud Model. Part II: Sensitivity Study
Publisher: American Meteorological Society
Abstract: Effects of different size distributions of cloud condensational nuclei (CCN) on the evolution of deep convective clouds under dry unstable continental thermodynamic conditions are investigated using the spectral microphysics ...
Polarimetric Radar Observation Operator for a Cloud Model with Spectral Microphysics
Publisher: American Meteorological Society
Abstract: he radar observation operator for computation of polarimetric radar variables from the output of numerical cloud models is described in its most generic form. This operator is combined with the Hebrew University of Jerusalem ...
Possible Aerosol Effects on Lightning Activity and Structure of Hurricanes
Publisher: American Meteorological Society
Abstract: According to observations of hurricanes located relatively close to the land, intense and persistent lightning takes place within a 250?300-km radius ring around the hurricane center, whereas the lightning activity in the ...
Collision Rate of Small Graupel and Water Drops
Publisher: American Meteorological Society
Abstract: An approach permitting one to calculate the collision efficiency and the collision kernel of spherical particles of different densities for Reynolds numbers up to 100 (300-?m-radius drops, or 700-?m-radius graupel) is ...
The Role of Small Soluble Aerosols in the Microphysics of Deep Maritime Clouds
Publisher: American Meteorological Society
Abstract: ome observational evidence?such as bimodal drop size distributions, comparatively high concentrations of supercooled drops at upper levels, high concentrations of small ice crystals in cloud anvils leading to high optical ...
Simulation of Effects of Atmospheric Aerosols on Deep Turbulent Convective Clouds Using a Spectral Microphysics Mixed-Phase Cumulus Cloud Model. Part I: Model Description and Possible Applications
Publisher: American Meteorological Society
Abstract: An updated version of the spectral (bin) microphysics cloud model developed at the Hebrew University of Jerusalem [the Hebrew University Cloud Model (HUCM)] is described. The model microphysics is based on the solution of ...
Factors Determining the Impact of Aerosols on Surface Precipitation from Clouds: An Attempt at Classification
Publisher: American Meteorological Society
Abstract: The simulation of the dynamics and the microphysics of clouds observed during the Large-Scale Biosphere?Atmosphere Experiment in Amazonia?Smoke, Aerosols, Clouds, Rainfall, and Climate (LBA?SMOCC) campaign, as well as ...
Combined Cloud–Microwave Radiative Transfer Modeling of Stratiform Rainfall
Publisher: American Meteorological Society
Abstract: The simulation of explicit particle spectra during cloud evolution by a two-dimensional spectral cloud model was used to investigate the response of microwave radiative transfer to particle spectra development with special ...
