Strato-Cumulus Clouds over San Gabriel Valley, Oalifoqda. The photograph which appears on the opposite page was innde a t a n

elevation of about 5500 feet during the late spring of 1921. Strato-cumulus sloutls are common over the San Gabriel valley, California, during the transition period between the cyclonic control of winter and the oceanic influence of summer. The writer, as a n aeronaut, has traversed these cloud formations from their lonest to their highest levels. Ofttimes several complete systems have been encountered in a single flight. In California the nlternat- ing desert and oceanic control contributes most interesting conditions and complicates the task of accounting for the rapid changes observed in cloud forms i n this locality. I t lias been my work dur ing the past quarter of a century as 5 meteorologist i n California to study and photograph cloud formations and to locate their origin and disappearance in cyclonic and anti- cyclonic areas. The strato-cumulus cloud forms as shown on the opposite page are invariably associated with the breaking up of cyclonic formations : they never occur during steadily decreaeing pressure. The strong convectional action does not destroy the clearness of the air within the first few hundred feet of the ground : this will be noted in the sharpness of the Pasadena suburbs shown i n the photograph. A 6x lemon-yellow ray-filter waa used i n connection wi th panchromatic plates in making clood photographs in this vicinity during free military balloon flights made for the purpose of adding to local meteora- logical knowledge.-FORD .ASHMAN CARPENTER, Sc.D., LL.D., Balloon Pilot, Fe'diration Akonautique Intcmationale.
