Abstract: Ice in atmospheric clouds undergoes complex physical processes, interacting especially with radiation, which leads to serious impacts on global climate. After their primary production, atmospheric ice crystals multiply ...

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 ...

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 ...

Abstract: easured ice crystal concentrations in natural clouds at modest supercooling (temperature ~>?10°C) are often orders of magnitude greater than the number concentration of primary ice nucleating particles. Therefore, it has ...
