Abstract

The design of an optimized computation scheme for kinematic vertical motion fields with an upper air network is discussed with a scheme that incorporates 14 degrees of optimization in the evaluation of divergence. The provided range of optimization enables the computation scheme to suit wide varieties of data dispostion in the observation network, and the well-known problem of bias error accumulation in the kinematic ω profiles seems to have been practically overcome. The discussions include the general construction of the scheme in terms of the sequential flow of the computation, the quality of the vertical motion field over the synoptic network through the depth of the atmosphere, and the utilization and application of the scheme under various circumstances.
