One method of reducing truncation error in numerical
prediction is the use of more accurate finite-difference
approximations. A relatively simple barotropic model,
similar to the one currently in use by the Fleet Numerical
Weather Facility (FNWF), Monterey, California, is employed
as a basic program in testing several higher order finitedifferencing
schemes. Forecasts were computed to 24 and
4# hours with modifications of the basic model, and
comparisons were made with the analyses at verifying time.
It is the intent of this study to determine the effects of
some higher order finite-difference approximations in this
numerical prediction model.

of FNWF for providing data and programming assistance.Approved for public release; distribution is unlimited.Lieutenant Commander, United States Navyhttp://archive.org/details/higherorderfinit109451228
