ABSTRACT: 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.
