On the Measurement and Nature of Atmospherics Produced by Electric Discharges in Snow Squalls and from Other Sources

This article deals with a special type of atmospherics produced within snow squalls. It discusses the possibilities of the genesis of such atmospherics. There is also a discussion of the theoretical principles and methods of measuring atmospherics by means of open-air antenna circuits and suitable cathode ray oscillographs. The article contains examples of typical meteorological situations with atmospherics of the type discussed. Special attention has been given to a case where a bank of cumulo-nimbus clouds was located near the east coast of the Baltic and visible from Uppsala. Examples are given of the typical variation forms of atmospherics produced in squalls within a limited range inside this cloud-bank.
