The use of multi-frequency radar measurements for investigating microphysical processes during DYNAMO/AMIE Angela Rowe and Robert Houze, Jr. University of Washington ASR Fall Working Group Nov 2013 Microphysics Breakout Rockville, MD Funded by NSF Grant # AGS-1059611 and DOE Grant # DE-SC0008452

  2. S-PolKa Zuluaga and Houze (2013)

  3. Hydrometeor profiles Ice crystals Ice crystals Dry Agg Dry Agg Graupel/Rimed Agg Graupel/Rimed Agg Wet Agg Wet Agg

  4. Z V PID Graupel

  5. Stratiform

  6. Squall line

  7. KAZR • KAZR within context of broader system • KAZR velocity providing additional kinematic information • Anvils KAZR S-PolKa

  8. Initial echo • Dual-polarimetric variables! S-PolKa

  9. Multi-wavelength radar network • Full spectrum of clouds • Microphysical details • Early echo • Warm-rain processes • Melting, fall streaks, anvil, etc. • Comparisons • Attenuation correction • Strengths of different wavelengths for particle identification (Brenda Dolan – MC3E) • Regional (Darwin/Manus) • What can the modeling community do with this information? • Mean profiles of dominant hydrometeor type • Vertical profiles or RHI snapshots of dual-pol variables?
