  1. LBA/Physical Climate Moist Convection in the Amazon

  2. Things models should do that LBA data has pointed out • easterlies/westerlies and convection • land features effects on convection • forest vs non-forest • topography • river vs land

  3. Rondônia 1999 850 hPa zonal wind - CPTEC

  4. Santarém 1999 850 hPa zonal wind - CPTEC

  15. TRMM-LBA Region: Forest vs. Non-Forest FOREST TOGA Profiler NON-FOREST SPOL Carey et al 2001

  16. TRMM-LBA Region: Topography “Elevated” >= 223 m “Non-Elevated” < 223 m Carey et al 2001

  17. Effects of Deforestation on Rain Rate Statistics Carey et al 2001

  18. TRMM-LBA: Effect of land type on rainfall statistics KEY: Fractional Rain Duration = % of grid boxes for land type category with rain (R > 0) Fractional Grid Coverage = % of all grid boxes for land type category Ru = Unconditional Mean Rain Rate Rc = Conditional Mean Rain Rate NE = Non Elevated (< 223 m) E = Elevated ( 223 m) F = Forested NF = Non Forested Carey et al 2001

  19. Carey et al 2001

  20. Effects of Deforestation on Cumulative Rain Depth Carey et al 2001

  21. Land Effects on Rain Depth Carey et al 2001

  22. Effects of Elevation on Rain Depth Carey et al 2001

  23. Elevated Only Forested Non-Forested Forested Non-Forested Non-Elevated Only Carey et al 2001
