Chemical retention during dry growth riming
[1] Partitioning of volatile chemicals among the gas, liquid, and solid phases during the conversion of liquid water to ice in clouds can impact distributions of chemicals in precipitation and in the poststorm troposphere. In this paper, we extend a theoretical scaling model of chemical retention during hydrometeor freezing to all dry growth riming conditions. We account for spreading of drops ...
متن کاملA wind tunnel investigation of the hydrodynamic behaviour of growing, freely falling graupel
The hydrodynamic behaviour of riming frozen drops and riming simulated ice crystal plates was studied by meansofavertical wind tunnel.At all times theiceparticles werefreelysuspended in thevertical airstream of the wind tunnel where temperature and liquid water content could be accurately controlled. The ice particles studied had initial radii between 100 and 300,um and final radii between 400 ...
متن کاملSecondary ice particle production during rime growth : the effect of drop size distribution and rimer velocity
The rate of production of secondary ice particles during the growth of rime in a supercooled cloud at about -5 "C is known to depend mainly upon the rate of accretion of large drops (diameter 325 pm). New experiments have defined more clearly how 'splinter' production is affected by the rate of accretion of small drops (diameter ~ 1 2 Fm). The relationship between secondary ice production and r...
متن کاملRefinements to Ice Particle Mass Dimensional and Terminal Velocity Relationships for Ice Clouds. Part II: Evaluation and Parameterizations of Ensemble Ice Particle Sedimentation Velocities
This two-part study addresses the development of reliable estimates of the mass and fall speed of single ice particles and ensembles. Part I of the study reports temperature-dependent coefficients for the massdimensional relationship, m aD, where D is particle maximum dimension. The fall velocity relationship, Vt AD , is developed from observations in synoptic and low-latitude, convectively gen...
متن کاملIce particle growth under conditions of the upper troposphere
Article history: Received 18 January 2010 Received in revised form 1 April 2010 Accepted 27 May 2010 Atmospheric conditions for growth of ice crystals (temperature and ice supersaturation) are often not well constrained and it is necessary to simulate such conditions in the laboratory to investigate such growth under well controlled conditions over many hours. The growth of ice crystals from th...
