摘要

One rainstorm over the North Pacific is studied and compared to a single dynamic fluid flow equation in order to see what measure of agreement might occur. Meteorological data for the rain storm come from the bridge of an oceanographic ship that sailed from San Diego to Japan along 35°N in the spring of 1976 [1]. A single dynamic equation origi-nated from combining Bernoulli’s law with the geostrophic relation and eliminating the pressure between them [2]: horizontal wind shear equals the Coriolis parameter. Wind speed measured on the ship every two hours is used to compute the mean wind shear over the 48 hours of the rain storm. That shear has the right sign and order of magnitude to agree with the Coriolis parameter at 35°N.
