The Doppler radar data are analyzed with the NCAR Variational Doppler Radar Analysis System (VDRAS) software and standard VAD techniques to examine a variety of mesoscale flows. The following mesoscale phenomena are documented within the heat burst: a) During its initial stages, the heat burst was marked by penetrative downdrafts that produced intense gravity waves within the developing nocturnal inversion over and around the MIPS site. The initial standing wave produced a 3-5 m/s updraft over a 20 minute period. WSR-88D measurements around this gravity wave showed appreciable radial convergence (25 m s-1 over several km) and a fine line, indicative of a convergent boundary zone. Less intense gravity waves persisted throughout the remainder of the event. b) The combination of mesoscale downdrafts (diagnosed using VAD analyses) and individual microbursts produced significant warming and drying within the 0.5-4.0 km layer. The evolution of this warming and drying was well documented with the MIPS 915 and MPR. c) The unstable dry layer that developed was conducive to microbursts and generation of large eddy turbulence that was diagnosed by the 88D and 915 measurements. d) Intense meso-gamma-scale circulations appeared to be generated by the collision of individual microburst outflows. One such circulation was directly sampled by the MIPS instruments.
