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

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
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

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!!!
