Abstract

This theoretical study is carried out to investigate the effect of radiation on ice crystal spectrum in the upper troposphere. First, an explicit expression is obtained for the ice crystal growth rate that takes account of radiative and kinetic effects. Second, the expression is used to quantitatively analyse how radiation broadens the ice crystal spectrum and then to reveal a new precipitation mechanism in the upper troposphere and the stratosphere. Third, the radiative effect is used to explain the subvisual clouds near the tropopause. Copyright Β© 2008 Royal Meteorological Society

We report a search, at wavelengths between 402 and \(850 \mathrm{~nm}\), for anomalies in the Venus polarization curve near the \(22^{\circ}\) halo scattering angle for ice crystals (phase angle \(158^{\circ}\) ). Such anomalies, if present, can be interpreted as due to halo birefringence peaks. Ano

The population balance equation with respect to ice crystal size in a batch crystallizer was solved, taking into account the crystal size dependency of growth rate, and the temperature change with crystal growth was calculated. Both the temperature change and the crystal size distribution obtained t
