Higher order finite-difference approximations in numerical weather prediction
higherorderfinit00chin.pdf (3.094Mb)Abstract
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.
The author expresses his appreciation to Professor
George J. Haltiner for his suggestions, guidance, and
patience. Appreciation is also expressed to the personnel
of FNWF for providing data and programming assistance.
