Upper Air Temperatures and Thunderstorms

Abstract

IN NATURE of November 14, 1925, p. 709, I directed attention to the method of plotting upper air temperature readings by the use of temperature and log. potential temperature as co-ordinates, the curves being designated tephigrams by their inventor, Sir Napier Shaw. It may be recalled that, by the use of these curves, the energy available from a mass of air rising under unstable conditions is shown directly as an area on the graph. Opportunity has now been taken to study these diagrams in connexion with thunderstorms in the south-east of England during the three months June, July, and August of last year, and the results obtained are of interest.
