Phase space parametrization of rain: the inadequacy of the gamma distribution
Phase space parametrization of rain the inadequacy of gamma distribution
2012/11/23
We show that the Gamma distribution is not an adequate fit for the probability density function of drop diameters using the Kolmogorov-Smirnov goodness of fit test. We propose a different parametrizat...
A diffusion-induced transition in the phase separation of binary fluid mixtures subjected to a temperature ramp
diffusion-induced transition binary fluid mixtures temperature ramp
2011/8/16
Abstract: Demixing of binary fluids subjected to slow temperature ramps shows repeated waves of nucleation which arise as a consequence of the competition between generation of supersaturation by the ...

The global spatial and diurnal distribution of cloud properties is a key issue for understanding the hydrological cycle, and critical for advancing efforts to improve numerical weather models and gene...
Study of contrail microphysics in the vortex phase with a Lagrangian particle tracking model
contrail microphysics a Lagrangian particle tracking model
2010/11/3
Crystal sublimation/loss is a dominant feature of the contrail evolution during the vortex phase and has a substantial impact on the later contrail-to-cirrus transition. Previous studies showed that t...

Measurements of OH and HO2 yields from the gas phase ozonolysis of isoprene
OH and HO2 yields gas phase ozonolysis isoprene
2010/2/21
The reactions of ozone with alkenes are an important source of hydroxyl (OH) radicals; however, quantification of their importance is hindered by uncertainties in the absolute OH yield. Hydroxyl radic...
