  1. The DYNAMO/AMIE Radar Plan R. Houze, C. Long, S. McFarlane, C. Schumacher, S. Rutledge, S. Ellis, M. Katsumata ASR Meeting, San Antonio, 30 March 2011

  2. DYNAMO/AMIE Objective • Determine the evolution of the cloud population and humidity field in the region where the MJO disturbance develops • Do this with radar!

  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 & AMIE Radars Revelle, Scanning C-band, VP W-band 28 Sep-30 Oct, 4 Nov-9 Dec, 13 Dec-4 Jan (?) S-PolKa, S & Ka band SMART-R, C band SACR, X & Ka band KAZR, VP Ka band Mirai, Scanning C-band, VP W-band 1-24 Oct., 31 Oct-28 Nov., + some cruising ~800 km

  5. Island Radar “Supersite” Spit SMART-R: 3-D PPI scanning, precipitation & Doppler velocity Wharf S-PolKa: PPI & RHI scanning for polarimetric microphysics, Doppler, dual λ humidity & CLW SACR: mixed scanning by PPI, BLRHI, zenith RHI, for non-precipitating cu and anvils Airport KAZR: VP Ka band for non-precipitating clouds Addu Atoll

  6. Summary • Ship and island radars will determine the evolution of the cloud population and humidity field during the buildup of the initiating disturbance of the MJO • This effort links with the Manus part of AMIE, which will sample the MJO disturbance after it has been initiated over the Indian Ocean
