Detailed plots for 21 Jan 09

CAMRa scan 1659 - cutting across a fall streak:


Circles are along aircraft track: corresponding images:
30km range: "junk ice" - mainly rosettes/sideplanes seems + a few columns? - radar=low ZDR

50km range: plate/stellar crystals - radar=high ZDR

70km range: plate/stellar crystals - radar=high ZDR

90km range: sideplanes and aggregates - radar=low ZDR

Later in the flight see quite a bit of embedded convection:


See the plumes of high reflectivity at 45-60km range in this scan with high ZDR at the very tops where glaciating. Can also see remnants of previous convective elements in high Z/ZDR patterns falling toward the radar (30-40k range, 2-4k altitude)

Finally, we also saw evidence for Kelvin-Helmholtz billows in the shear structure - eg this RHI from 1930:

note the braided structures at approx 300-1500m, at 25-60k range - compare these to the paper by Chapman and Browning
