An application of one dimensional numerical forecasting in the Australian region

Key Points

To explore the feasibility of using one-dimensional numerical forecasting in the Australian region.
Applied numerical integration with a five-degree grid interval to a differential equation of motion.
Utilized the equivalent barotropic model based on Charney's approach.
Created a two-dimensional forecast by juxtaposing forecasts along adjacent latitudes.
The one-dimensional forecast can offer practical advantages when combined with subjective prognostic techniques.
The two-dimensional forecast requires significant preparation time and is considered uneconomical.

Abstract

A five degree grid interval for numerical integration was used in the solution of the one dimensional differential equation of motion to the equivalent barotropic model (after Charney 1949) using data in the Australian region. The forecasts along adjacent latitudes were then juxtaposed (after Gates 1953) and a "two dimensional" forecast obtained. The "two dimensional" forecast requires considerable time for preparation and is thus uneconomical by our present standards, however, it is suggested that a one dimensional forecast along a selected latitude (say 40°S) When incorporated with the usual subjective prognostic may be used to practical advantage.
