On the Role of the Tropics in the General Circulation of the Atmosphere

Dear Sir: In a recent issue of Tellus (Vol. 2, No 1) Mr Herbert Riehl published an interesting article on the subject indicated above, bringing new results and valuable information concerning the structure of the tropical atmosphere. My own meteorological and aerological observations in Mogadiscio (Italian Somaliland, Lat. 2°02’03’’ N , Long. 45°21’20’’ E) during the International Polar Year 1932–1933 appear to have considerable hearing on the problems discussed by Mr Riehl. Since these observations have not yet been printed in extenso, even though sonic partial results have been published, I shall take the liberty of calling attention to two groups of deductions from the Mogadiscio data, both related to Mr Riehl’s analyses.
