Bow Echo and
Mesoscale
Convective Vortex Experiment (BAMEX)
Located at Mid America Airport, Mascoutah, IL Dates: 20 May to 6 July 2003
The focus of my
BAMEX-related research is the structure and life-cycle of the
long-lived mesoscale convective vortex (MCV) of 10-14 June 2003.
This work is supported by the National Science Foundation under grants
ATM-0233172 and ATM-0646907. The results of this study are found
in my Master's thesis which was completed in May 2007:

multiscale examination of the long-lived mesoscale convective vortex of
10-13 June 2003. M. S. Thesis, The University at Albany, State

Long-lived
MCV of 10-15 June 2003:
MCV-centered azimuthally
averaged time series. Wind shear is averaged over a radius of
*500
km* while all other fields are averaged over a radius of *200 km*.
1. The dynamic tropopause (DT) is defined at the 1.5 potential
vorticity
unit (PVU) surface
2. The coupling index (CI) is a measure of atmospheric stability
and
is defined as CI=(THETA)DT-(THETA-E)@850 hPa
- CI < 4 K (< 0 K) considered conditionally
(convectively)
unstable (see Bosart and Lackmann 1995)
