climb-out, stair-step descents through cloud,
pass through remote sensing sites, climb
through cloud, descent, flux legs, and
the power plant run.

2. Figure 2. (Left) The step-down through the cloud, showing a profile of supercooled liquid water.
(Right) The clear-air sounding, showing the profile of aerosol.

3. Fig. 3 Pass through supercooled liquid water at -35 C, which is unusually cold for liquid water.

4. Figure 4 Two photographs of a Kelvin-
Helmholtz Billow cloud. Note the
photo to the left (which was taken a few
minutes after the upper photo) shows the
cloud has “wrapped up”.
