## Kinematic
and Microphysical Statistics for 990223

*Note:
results on this page represent work in progress and caution should
be excercised in their interpretation*
This page contains volume average
statistics of selected fields (vertical air motion, vertical mass
flux, reflectivity, liquid water content, precipitation ice content,
and near surface precipitation) for the 990223 event between 2002-2130
UTC. The 2002-2130 UTC period was chosen since the system was
captured in the east dual Doppler lobe at this time. Prior to
2000 UTC, the vast majority of the system was positioned outside
the area of dual-Doppler sampling. After 2130 UTC, the system
was largely decaying. The dual Doppler sampling period was probably
most representative of the mature to disspitating stage of this
event.

Dual-Doppler analyses were performed
at 10 minute intervals over a 14,400 km^2 grid domain centered
on the location of the SPOL radar (X_min=-45, X_max=75, Y_min=0,
Y_max=120) using 1 km horizontal and 0.5 km vertical grid resolution.
Microphysical retrievals were calculated using SPOL data over
the same 2002-2130 UTC time period with a grid (centered on SPOL)
extending over a 40,000 km^2 domain (X_min=Y_min=-100, X_max=Y_max=100)
with 2 km horizontal and 0.5 km vertical resolution. Although
the grid domain specified for the microphysical retrievals is
significantly larger than the dual-Doppler domain, they are actually
much closer in size since SPOL was conducting sector scans covering
the dual-Doppler lobe only during this time period. Thus, much
of the domain in the microphysical retrievals (i.e., outside the
dual-Doppler lobe) contains no data.

The methodology used to calculate
kinematic and microphysical fields is similar to the procedures
outlined in Cifelli et al. 2001.
