  1. DYNAMO Radar Plan R. Houze DYNAMO Planning Meeting, Seattle, 6 July 2010

  2. DYNAMO Hypotheses • Deep convection can be organized into an MJO convective envelope only when the moist layer has become sufficiently deep over a region of the MJO scale • Specific convective population at different stages are essential to MJO initiation • Upper ocean processes play essential roles in MJO initiation in the Indian Ocean DYNAMO radars will address 1 & 2

  3. This has never been done! * HUMIDITY DOPPLER Air motions DUAL WAVELENGTH Water vapor CM-WAVELENGTH Precipitation MM-WAVELENGTH Non-precipitating Cumulus MM-WAVELENGTH Anvil cloud POLARIMETRY Microphysics

  4. DYNAMO observing network and TRMM 3B43 Oct-Dec precipitation climatology Gan Ship radar 1 Ship radar 2 Diego Garcia

  5. Proposed Radars AMF2 — Long, proposal to DOE • Vertically pointing mm-wavelength Doppler radars (also on ships): • X- band polarimetric Doppler radar • Ka-band polarimetric Doppler radar SMART-R — Schumacher, proposal to NSF/JAMSTEC • C-band Doppler radar S-PolKa — Houze, Medina, NSF facility request • S- and Ka-band polarimetric Doppler radar Ship radars — Rutledge, Fairall, Brewer, NOAA ship Revelle, Yoneyama, Japan ship Mirai • C-band Doppler radar • Vertically pointing mm wavelength cloud radar Aircraft radar — Fairall, Jorgensen, NOAA request • X-band dual-Doppler radar • Lower-fuselage C-band radar NOAA S-band profiler? — Williams, NOAA request

  6. Installation sites suggested by survey team SMART-R SPolKa/SACR? 5 km Addu Atoll AMF2(MMCR?)/SPROF?
