A DIAGNOSTIC-CYCLE ROUTINE.
Abstract
A 'diagnostic-cycle routine' is designed for the numerical processing of information relating to the atmosph'ee's evolution, in twelve-hour periods defined by successive collections of synoptic upper-air observations. The rouenne is applied in terms of one or more selected isen tropic surfaces, and, for eac; surface, consists of: (1) inferring the evolution of required state parameters, (2) evolving the distribution of horizontal velocity as forced by the inferred evolutio of the pressure-gradient force, and (3) evolving the distribution of concurrent horizontal parcel-displacement, and calculating the corresponding net vertical displacement of air parcels as terminally distributed in the sur face. The method of evolving the horizontal velocity is of fundamental significance in the application of the quasi-static equations system (i.e. the primitive equations) to analysis and prediction. The routine directs available in formation into the evolution of the velocity in order to achieve accuracy in the rotational and divergent components, and includes an evaluation of the dynamical consistency with the concurrent state-parameter tendency. The interpolation of the state-parameter distributions, between analyses successive in time, is to be accomplished by combining the concept of a steering flow with a technique for scale-and-pattern decomposition.
