Abstract: A kinetic analysis of the fog formation process due to the contact of warm, moist air with a cold wall is presented. The analysis reveals that a wave in the nominal saturation ratio forms at and spreads away from the wall. ...

Abstract: A new cloud condensation nuclei (CCN) spectrometer capable of simulating the desired range of cloud supersaturation in a single chamber is developed. It can rapidly and continuously measure and display the spatial and ...

Abstract: Cyclic temporal variations of pH and ionic concentration in sampled clouds which traversed the Mt. Mitchell State Park site (35°44?05?N, 82°17?15?W, 2006 m MSL) during the summers of 1986, 1987 and 1988 are reported. These ...

Abstract: The effect of transient supersaturations on the concentration of cloud condensation nuclei (CCN) in a conventional parallel-plate type thermal diffusion chamber is experimentally investigated by controlling the relative ...

Abstract: An analysis of a 3-yr database (1986?88) acquired new Mount Mitchell (35°44?05?N, 82°17?15?W, 2038 m MSL) where the forest consists primarily of Fraser fir and some red spruce stands is presented. The site was immersed in ...

Abstract: Variations in the chemical composition of cloud droplets of different sizes are predicted in models. Measurements made in natural clouds to verify this prediction are extremely limited, however. During the spring of 1995 ...
