1. Determine
the morning stability at KOUN (Norman, OK) from the morning sounding for 1200
UTC 3 May 1999 (attached).

Estimate the height of the Lifting Condensation Level, Level of Free
Convection, 500 mb Lifted Index, Equilibrium Level and determine if the
sounding is unstable, stable or conditionally unstable with respect to a
SURFACE LIFTED PARCEL. Be sure to indicate the parcel ascent curve, LCL, LFC
and EL right on the diagram.

This is a conditionally unstable sounding. The LCL is at about 930 mb (162 m AGL), the LFC is at about 700 mb (~3000 m AGL), and the EL is at about 240 mb (~10,500 m AGL). The Lifted Index is -2.4.
