Observations of microwave noise due to rainstorms have been made at 1415 Mhz. The observed effect may well be due to electrical discharge between water droplets. 
The role of rain in satellite communications
The most fundamental obstacle encountered in design of satellite communication systems at frequencies above 10 GHz is attenuation by rain. The microwave power radiated toward an earth station, beingExpand
The microwave emission spectrum from sparking water drops
The microwave emission spectrum is obtained for the discharge during collision of two oppositely charged water drops of equal size in the absence of an external electric field. The power spectraExpand
Clouds and precipitation
In these days of emphasis on environmental problems, studies of clouds and precipitation take on an added importance. Clouds and precipitation cleanse the atmosphere of natural and manmade pollutantsExpand
Shear‐induced electrical changes in the base of thin layer‐cloud
Charging of upper and lower horizontal boundaries of extensive layer clouds results from current flow in the global electric circuit. Layer-cloud charge accumulation has previously been considered aExpand
Cosmological Perturbation Theory
Firstly, a dynamical analysis of adiabatic perturbations of a perfect fluid is performed to first-order about a general FLRW background using the 1 + 3 covariant and gauge-invariant formalism. The 1Expand

Charge Transfer between Raindrops
TLDR
Electric discharges between free-falling drops suggest that augmentation of the UHF temperature of thunderstorms by discharges could amount to 117�K. Expand
