Synoptic Metr Homeworks 6 and 7 and In-class Exercise/Lab

Due Monday 3/28/05

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.

2. Estimate the afternoon stability at KOUN (Norman, OK) from the morning sounding for 1200 UTC 3 May 1999 (second copy). Estimate the Convective Temperature, Convective Condensation Level and determine if the sounding is potentially unstable. Indicate the CT, CCL, parcel ascent curve, positive area on sounding (CAPE) (shaded red), and negative area on sounding (CINH) (shaded blue).

3. Calculate the CAPE from the morning sounding using the method discussed in class. (Started in class)

4. Using the results from (3) above, calculate the maximum vertical velocity at the EL. (Started in class)
