  2. Cloud processes of tHe main precipitation systems in Brazil: A contribUtion to cloud resolVing modeling and to the GPM (GlobAl Precipitation Measurement) CHUVA Project: 2010-2011 and Perspectives for 2012-2014 CHUVA Science Team 6

  3. CHUVA Project: Main Goals • Improve Rainfall Estimation Using Satellites and/or Radar • Improve the Skill of Cloud Resolving Models • Compile a Climatology of the Main Precipitation Systems in Brazil and their physical and microphysical characteristics • Develop Tools for Nowcasting. WORKING GROUP–1: CHARACTERISTICS OF THE PRECIPITATING SYSTEMS AS FUNCTION OF THE REGION AND LIFE STAGE (Luiz Machado) WORKING GROUP–2: PRECIPITATION ESTIMATION – DEVELOPMENT AND VALIDATION ALGORITHM (Daniel Vila) WORKING GROUP–3: ELETRIFICATION PROCESS: MOVING FROM CLOUDS TO THUNDERSTORMS (Carlos Morales) WORKING GROUP–4: CHARACTERISTICS OF THE BOUNDARY LAYER FOR DIFFERENT CLOUD PROCESSES AND PRECIPITATION REGIMES (Gilberto Fisch) WORKING GROUP–5: MODEL IMPROVEMENTS AND VALIDATION, WITH FOCUS IN CLOUD MICROPHYSICS AND AEROSOL INTERACTIONS, FOR SATELLITE PRECIPITATION ESTIMATES IN BRAZIL (Maria Assunção Dias)

  16. CHUVA-GLM Vale do Paraíba • CHUVA-GLM Vale do Paraíba ends 31 March 2012. • 5 months of continuous data: • Local convection due to thermodynamics • Local convection due to topography • Cold fronts • Convection from South Atlantic Convergence Zone (SACZ) • Squall Lines • Severe Weather (20+ cases of hail storms, damaging winds, flooding): • Severe Weather reports are being gathered from Civil Defense, Newspapers, TV news, Internet sources (blogs, social networking, etc.), Insurance Companies

  17. CHUVA-GLM Vale do Paraíba • 07 January 2012: • Pea sized hail at 15:40LST in downtown São Paulo • Future goals: • Develop nowcasting of severe weather and lightning

  18. NEXT FIELD EXPERIMENTS Santa Maria, RS – South Brazil Main Goal: Mesoscale Convective Systems November - December 2012 In the region of two S Band Radar overlapping and a mesoNet

  20. NEXT FIELD EXPERIMENTS Santa Maria, RS – South Brazil 22 March 2012 22 March 2012

  21. NEXT FIELD EXPERIMENTS Brasília, DF – Central Brazil Main Goal: Continental convective processes - Savanna March 2013. Additional Data: S Band Radar

  22. NEXT FIELD EXPERIMENTS Manaus, AM – North Brazil Main Goal: Tropical Forest Continental Convection February- March 2014 (with a possible extension to +9 months) Additional Data: The ARM Climate Research Facility in the Amazon Basin ( Havard University and several partners) - S Band Radar (SIPAM)

  23. NEXT FIELD EXPERIMENTS Manaus, AM – North Brazil

  24. CHUVA contribution to CWG • CHUVA is collecting data from a large variety of convective systems over Brazil: • Several Golden Cases from tropical convection trough large MCSs • Brazil is observed both by GOES and MSG: • Great environment for GOES-R and MTG activities: • Risk Reduction (nowcasting algorithms) • Algorithm Working Group (proxy data) • Calibration/Validation • We are open to additional measurements: • You can bring your instruments to the field experiments • CHUVA data is openly available for the research community: • Collaborations are greatly welcome!!!
