Abstract
This study examines the microphysical and environmental conditions necessary to support rapid coalescence growth in warm convective clouds. A quantitative threshold for effective coalescence growth can be defined in terms of the massβdoubling times for growing precipitation embryos.

## Abstract The collection efficiencies of water drops falling in still air have been recalculated by Hocking and Jonas (1970). In this paper these revised values have been used to estimate the rate of production of large droplets (__r__ > 30 ΞΌm) by coalescence. It is found that there is an increas
## Abstract Calculations of collision rates between cloud droplets in turbulent air show that this would be an effective precipitation mechanism in cumulus if the r.m.s. turbulent acceleration were about 3 times that due to gravity. An estimated value, based on published records of flights through
