Atmospheric electricity during disturbed weather

From October, 1942, to May, 1946, a special investigation of, atmospheric electricity during disturbed weather was undertaken at Kew Observatory, England, with special reference to the electricity carried on rain and snow. The results obtained have been discussed in detail in a paper which is to be published as Geophysical Memoir No. 84 by the London Meteorological Office. Owing to shortage of paper and other difficulties resulting from the war it may be some considerable time before the Memoir is printed and distributed. The Director of the Meteorological Office has therefore approved of the following summary of the conclusions reached in the work being made available in advance of the publication of the Memoir.
