NOTES for 20June 2000 Case

Nov. 5, 2002

Isolated, very tall cells with no anvil

CAPPIS with lightning show lightning in the first cell by time of
first radar volume ~2000.
The isolated small storm with no shear and no obvious anvil
moves to the SW. Last flash in this cell was at ~2110.
CAPPI w L 2107-2110

The A/C first penetrates at ~2151 and finds Emag of ~20 kV/m
at 2156 and ~40 kV/m at 2158.
CAPPI w L 2155-2157
MER 2150-2200

The A/C then moves to larger cell a little to the SE which from
~2210-2220 MER
shows radar tops of 19 to 20 km.

A/C flies through the core at ~2234 and again at ~2239 and also
shows radar tops to 19 km and lightning occurring in the cell
and nearby during the passes. (Lucky we didn't get struck.
Emag was 20 to 30 kV/m at 9 km altitude, but shows lots of
structure suggestive of being in the thick of things electrically. 
CAPPI w L 2234-2237
MER 2230-2240.

Later the A/C stayed more on the edge of the cells so E fields were weak
but cells were still quite strong and producing lightning.
CAPPI 2324-2327
MER 2320-2330

The scatter plots for 74 C look normal with all points below 5 dBZ
having E fields < 3kV/m.  The NEXRAD plots have two points for
10km box in this zone, but 5km box does not. Something strange
happening with 10km NEXRAD box avg.
