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 thunderstorms, is about one‐sixth of gravity. In the absence of more direct evidence, it seems that turbulence is not an important factor in convective precipitation.

## 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 mass‐doubling times for growing precipitation embryos.

Thermal measurements of the onset of turbulence in normal liquid helium have been made in cylindrical containers with aspect ratios r = 6.22 and 7.87. (Here r = D/2d, where D is the diameter, and d the height of the fluid layer.) We find qualitatively different behavior for the onset of turbulence i
