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.
