| Summary: | analysis period while the convective intensity of the and central portions of the storm. In contrast, the northern and Research Meteorology-Centml Phase (PRE-STORM). Ten dual- appears to have resulted from a scale interaction between the associated with an embedded mesovortex in the trailing central portions of the convective line compared to the consistently found on the southern flank of the system. The constructed for roughly a 50-minute period over the storrif s convective downdraft outflow such that there was greater low- convective line and the mesoscale stortn-relative flow direction of storm propagation, were located in the southern Doppler analyses of the kinematic and reflectivity fields are examined using Doppler radar data collected during the inflow. The outflow was opposite the environmental inflow in leading convective line. The variability in the structure of level convergence and enhanced lifting in the southern and mature stage. Reflectivity and flow fields exhibit more closely spaced reflectivity cores which were organized northem part. Hence, the variability in convective structure northern end of the line continuously decreased. A well organized cyclonic mesovortex was found at midlevel in the outflow from this vortex and the environmental low-level part of the convective line was characterized by smaller, perpendicularly to the storm propagation vector. Deepest Preliminary Regional Experiment for Stonnscale Operational reflectivity cores and strongest vertical drafts were related to the interaction between the mesoscale low-level significant variability along the convective line. Large, somewhat isolated reflectivity cores, elongated in the southern end of the convective line expanded during the storm-induced relative flow and the environmental winds. stratiform cloud trailing the north-central portion of the stratiform region of the 28 May 1985 squall line system is the convective cers along the convective line appeared to be the northem portion of the storm system. This led to the outflow was directed nearly parallel to the inflow along The relationship between the kinematic structure of the the southern and central portions of the storm. In contrast, variation in the depth and direction of propagation of the |
