Abstract

Short-period internal gravity waves recorded at Palisades, N.Y., have been found to associated with a rapidly moving pressure rise explained as a very long gravity wave. The speeds of propagation of both the pressure rise (long wave) and short-period gravity waves are nearly the same and although they show fairly good agreement with the theoretical propagation speed of long internal gravity waves, the problem is not regarded as fully solved.
