An Application of Singularity Analysis to a Heavy Precipitation Event

Abstract

On 27 May 1987, a mesoscale convective complex (MCC) brought heavy rains and flash flooding to the central portion of Oklahoma. A two-pass Barnes analysis is used to analyze the rainfall data recorded by 29 raingage instruments in the Oklahoma raingage network. The precipitation analysis is compared with a singularity analysis of Doppler velocity data. The singularity analysis produced three separable classes of divergence singularities: (1) Divergence singularities associated with a gust front; (2) Divergence singularities associated with the precipitation; and (3) Divergence singularities associated with velocity folding.
