Abstract: Recomputation of the collision efficiency of nearly equal water drops falling in air gave values which increase as the size ratio approaches unit for radii of the bigger drop larger than 63 µ, and decreased as though tending ...

Abstract: Using Eppley pyrheliometers mounted on a blimp, observations were made of the upward and downward flux of short-wave radiation above, in, and below coastal stratus throughout the summer of 1945. These observations are ...

Abstract: While the temperature at which ice is in equilibrium with a solution (equilibrium freezing point of the solution) is invariably lower than the corresponding value for pure water, in actual experiments in which the temperature ...

Abstract: During 1957-63 a randomized experiment to test the efficacy of cloud seeding to suppress hail in the southern Alps was conducted using ground-based silver iodide generators. While the results from the standpoint of hail ...

Abstract: From a statistical analysis of geostrophic- and gradient-wind computations for all stations reporting winds on two 700-mb charts, it is shown that there is a variability of about 25 per cent in the computations by different ...
