Sulla natura fisica delle onde interne del lago di Bracciano

It is a well know fact t h a t , at an average depth of 15 m, during t h e summer and the fall, remarkable internal waves appear in the lake of Bracciano — as Prof. Caloi has shown — such waves must be explaned by free oscillations of the surface of thermic jump, which takes place in the lake in those months. On the basis of a long series of recordings, taken in two lymnographic stations operating at the estremes of a diameter of the lake, it was possible to prove that the Bracciano lake internal waves are of asymmetric type, according to the theory.
