Abstract: Typical results of field measurements of the fallspeeds of natural raindrops are presented and instrumental effects investigated by numerically simulating the measurement processes. Deviations between the measured fallspeeds ...

Abstract: Preliminary data from ground-based measurements of rainfall using an optical disdrometer and high-resolution rain gage network are described. The recurrence of the rain period is shown to be non-Poisson with evidence of ...

Abstract: Examination of the arrival-rate distribution of raindrops from disturbed, post-cold-front air masses using the statistic k, the ratio of the variance of the drop rate to the mean, shows strong deviations from Poisson ...

Abstract: The effect of horizontal drag forces on raindrop trajectories is shown to influence strongly the detection efficiencies computed for drop cameras and disdrometers. Two examples of sheared flow involving real instruments ...

Abstract: Evaluation of an earlier raingage design based on counting drops formed on the tip of a small-diameter stainless-steel tube shows a defect due to resonant oscillation of the water column in the dropper unit. The defect ...
