010527 -- Case Summary
Flight Times: 2125 - 2437

ANVIL CASE DAY

No attenuation of 74C radar for this case.


Case 1 Early stage of developing anvil.
Case 2 This looks to have been part of the anvil studied in Case 1 that
broke away, but the MER plots suggest it is debris. Did it dissipate, or
was it consumed by a larger, growing anvil?
Case 3 The anvil that collided with CAse 2. The flight covers more than one
"finger" of the anvil.
Case 4 This is a well developed 25-35 dBZ region at 4 km. It briefly
develops a 35 dBZ region at about 2346.
Case 5 This is the anvil associated with the decaying cell of Case 4.

It is not clear how separate these cases are. The convection is roughly
stationary and made up of different cells that develop, combine, and
separate again, while the anvil(s) come off like fingers at the 7-8 km
level.


The system as a whole is an extended anvil case; mostly examined far extent of
the anvil in weak reflectivity while storm continued to produce
lightning, later looked in moderate reflectivities

There were cells developing on land between Vero Beach and Melbourne
producing an anvil to the East. The cell(s) showed some lightning
during the flight. New cells developed beside or behind
the old ones but fed into the overall anvil. First passes were through
the East 'tip'of the anvil - low fields were reported. Towards the last
part of the flight the Citation made some East - West passes and from
23:22 UTC on there were some stronger electric fields in higher
reflectivities.
