The Upper-Air Analysis Capability, FIB/UA Introducing Weighted Spreading.
Abstract
The Fields by Information Blending (FIB) methodology, based on fundamental and generalized information-processing concepts, is a comprehensive technique for the analysis of scalar and vector fields with a wide range of realized and potential applications. In general such applications lead to a system of linear equations which normally is too big to permit solution by explicit matrix inversion. Hitherto the sole recourse for solution of such systems has been to Successive Over-Relaxation (SOR) techniques which require a first-guess solution and also converge at an undesirably slow rate. This Report details the development of a new technique, termed Blending by Weighted Spreading, for producing an effective solution to the system of linear equations arising from FIB applications. This technique, described in the context of its initial application in an MII-developed upper air analysis system (FIBUA), produces an effective solution to the system of linear equations which converges far more rapidly than SOR schemes alone and, of particular note, no first-guess solution is required. It is expected that all future FIB-based analysis systems, where appropriate, will utilize the new technique--Blending by Weighted Spreading. (Author)
