Abstract: A method is described by which the coalescence process can be examined for different drop and droplet sizes. Preliminary experiments show that factors such as the velocity of collision, the angle of impact, the surface ...

Abstract: The development of precipitation was studied in southern Africa in 23 clouds, 12 unseeded and 11 seeded, from 11 days during the Bethlehem Precipitation Research Project. Surface and upper air data were used to describe ...

Abstract: Calculations are made on the growth of hailstone embryos of given size and concentration which are injected into a one-dimensional steady-state updraft, and grow while ascending, the updraft obeying the condition that ?Vs ...

Abstract: The evolution of raindrop spectra by collisional breakup is examined analytically and modelled in box and 1-dimensional shaft models, using the parameterization of Low and List. The significant analytical result shows that ...

Abstract: Calculations are presented of the relative contributions of heat exchange by conduction and convection, by evaporation, and by the supercooling of accreted drops to the total heat exchange of growing spherical hailstones. ...

Abstract: A randomized rain enhancement experiment was carried out during 1988?94 in the area of Bari and Canosa, Italy, on the Adriatic coast. It was commissioned by the Italian Department of Agriculture and Forestry and the region ...

Abstract: The primary purpose of this article is the documentation of radioactivity data collected by airborne equipment during the first of the Nevada atomic tests. While absolute magnitudes of activity are not available, the ...
