Abstract
DR. MARGULES wrote his paper mainly in connection with phenomena of the line-squall type, but he realised that it might have wider applications, and later investigations do indicate that discontinuity of temperature is the prime factor in the “birth” of cyclones. If one had an atmosphere with uniform pressure at sea-level, but with masses of warm and cold air, then at 9 km. pressure would necessarily be low in the mass of cold air, and a cyclonic circulation would ensue; but the energy of the motion would be derived from the potential energy of the initial state.
