Abstract: The stochastic electrical numerical model of cloud growth and precipitation development of Scott and Levin (1975) has been refined to include a distribution of charge within each size class. Each size class is separated ...

Abstract: The charges carried on failing raindrops were measured simultaneously with the charges separated by splashing on solid metal surfaces. It was found that the ejected fragments carry predominantly negative charges leaving ...

Abstract: Use of the lognormal form of raindrop size distributions in simulations of differential reflectivity (ZDR) measurements is investigated. Using two remotely measured variables and an empirical relation, the three parameters ...

Abstract: Measurements of rain drop size spectra in Israel were carried out over a period of two years. It is shown that the size distribution can be best described by a lognormal distribution. With its parameters weighted by a ...

Abstract: A time-dependent numerical model is used to simulate the growth of the electric field in thunderclouds by the polarization mechanism, including both the growth of hydrometeors and the growth of the electric charge centers. ...

Abstract: Droplets freely suspended in the air stream of a wind tunnel were nucleated with dedicated bacterial cells in either the contact or immersion mode. Immersion freezing seemed to give a noncontinuous frequency distribution ...

Abstract: A stochastic numerical cloud model is used to investigate simultaneously growth of precipitation, the formation of electrical charges on the particles, and the development of the ambient electric field utilizing the ...

Abstract: Charge separation which occurs when polarized ice particles collide in a potential gradient has been found to be an extremely important charge generating mechanism. The fair weather potential gradient is sufficient to ...

Abstract: A new, accurate, efficient method for solving the stochastic collection equation (SCE) is proposed. The SCE is converted to a set of moment equations in categories using a new analytical form of Bleck&'s approach. The ...
