Abstract: The effects of simplifications in the derivation of the Köhler equation describing the equilibrium saturation ratio for solution drops as a function of size on the activation of a population of CCN in an updraft are examined. ...

Abstract: An adaptive, three-way interpolation model based on multiple discriminant analysis, multiple linear regression, and normal ratio methods was used to reconstruct streamflows for three gauges in central Arizona for the period ...

Abstract: Three different interpolation methods are compared for a network of 111 long-term precipitation stations in Arizona and New Mexico. The methods studied are 1) multiple discriminant analysis (MDA), which is based on empirical ...

Abstract: Ice particle multiplication mechanisms are summarized and considered to be incapable of producing the excess of ice crystals over ice nuclei (factors of 102?104) observed in several types of clouds. Contact freezing, ...

Abstract: The multi-level, microphysical cloud model described in the accompanying article is applied in an orographic situation to simulate the development of precipitation under both natural and seeded conditions. In the case ...

Abstract: A numerical model which extends treatment of microphysical cloud processes to more than one level through use of the continuous bin technique is described. A general solution to the diffusion growth equation including ...

Abstract: A numerical model of warm rain processes incorporating activation of cloud condensation nuclei, drop growth by condensation and stochastic coalescence, and drop breakup is described. A collisional breakup model is compared ...

Abstract: A method is described for simultaneously simulating maximum and minimum temperatures and daily precipitation amounts in a physically consistent manner. The method ?chains? actual days from a historical dataset by defining ...

Abstract: A heat budget model to predict heat stress in humans during exercise is developed. The model considers the transfer of heat by conduction/convection from the skin (C), the latent heat due to evaporation from the skin (E), ...

Abstract: Mixing processes within the hall growth zone are examined as they pertain to competition within a population of growing hailstones. Mixing is demonstrated to produce broader particle spectra than predicted by the deterministic ...
