Abstract: The effect of annealing in accreted ice has been investigated for artificially grown ice deposits after ?100 days of storage in a deep freeze unit. Cross sections of the cylindrical deposits have been cut and replicated ...

Abstract: The size of crystal grains in ice formed by accretion of supercooled droplets has been determined for a wide range of air (?11 to ?25°C) and deposit (0 to ?16°C) temperatures. At air temperatures of ?14°C and below, the ...

Abstract: The effect of size on ice nucleation has been experimentally investigated for aerosol particles in the aerodynamic range. Aerosol particles are separated according to their aerodynamic diameter while airborne and deposited ...

Abstract: The migration of water-insoluble particles during freezing was used to study the structure of ice grown by droplet accretion. Experiments were performed in a cold tunnel under different growth conditions using nickel powder ...

Abstract: Preliminary results of a chemical analysis of hailstone slice residues are reported. The radial pattern of Fe particles shows a marked outer ring of relatively high concentration. The possible causes are discussed and it ...

Abstract: The size and orientation of crystal grains in wet and spongy ice formed by accretion of supercooled droplets has been determined in a wide range of air temperatures (?8 to ?25°C). Particular care has been taken in reducing ...

Abstract: There are two populations of aerosol particles in severe storms: normal background aerosol and aerosolized soil particles. Concentration of the latter, which depends on local wind speed and soil conditions, may be orders ...
