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
• f 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!!!
