Precipitation Changes.warming, drying south

• Rainy climate
• MAP ? 1000-3000 mm
• ?(IA)/MAP ? 0.1
• Weak ENSO Impact
• Significant drying trend

Ref. Quintana, 2004

• Semiarid climate
• MAP ? 30-500 mm
• ?(IA)/MAP ? 0.3 0.5
• Strong ENSO Impact
• No significant trend

Improve the performance of Meteorological Models
Met. Models tend to overestimate Precipitation by
a factor 2 Should we better tune the
microphysical parameterization?
