Abstract: The ability of 329 selected organic compounds to nucleate ice has been tested by three methods. Their activity was found to depend strongly on the method of preparation. More than 20 compounds were found to nucleate ice ...

Abstract: The fall velocities and growth rates of freely falling ice crystals were measured at various intervals for about 1 min after ice crystal nucleation of a supercooled fog. Measurements were also made at various degrees of ...

Abstract: Ice nucleation and subsequent phase equilibrium in water held in the micro-capillaries of atmospheric particles are examined. It is found that ice formed in the micro-capillaries of certain particles may exist in equilibrium ...

Abstract: When a highly volatile liquid is sprayed into moist air the evaporation of the liquid droplets may cool the air sufficiently for the condensed water droplets to freeze by homogeneous nucleation. This paper describes the ...

Abstract: Aerosols of organic ice nucleating agents were formed by rapid adiabatic expansion, by passing superheated steam laden with the organic vapors through a supersonic nozzle. The effect of the Mach number of the flow through ...

Abstract: A continuous-flow, horizontal gradient, ice thermal diffusion chamber has been developed and tested for heterogeneous ice nucleation of aerosol particles under accurately controlled supersaturations and supercooling in the ...

Abstract: A probabillstic theory of heterogeneous condensation-freezing nucleation is developed for monodisperse aerosol particles. An assumption is made that the physical process is heterogeneous condensation nucleation followed ...

Abstract: Development of supersaturation around falling graupel in supercooled clouds was investigated numerically. The steady state temperature and vapor density profiles were obtained by solving the nonsteady state advective ...
