With the aid of an electronic computer, velocity
divergence, vertical velocity, and thermal advection
computations are performed at the standard pressure levels.
These parameters are then related to tropospheric pressure
systems, classified according to subsequent development or
non-development. Typical plan view and cross section
patterns are presented. The writers wish to express their appreciation to
Professor George J. Haltiner of the U. S. Naval Postgraduate
School for his guidance and assistance in this study.
Appreciation is also expressed to the personnel of the U. S.
Navy Fleet Numerical Weather Facility for their cooperation
during the preparation of this paper. We are especially
indebted to CDR. L. C. Clarke and LCDR M. Jane Seljos for
their aid and programming assistance.http://www.archive.org/details/distributionoftr00aldeLieutenant, United States Nav
