18. CONCLUSION Rainfall Estimation Accumulation Time (worst -> best r2)
Daily (0.10) -> Monthly (0.58) -> Yearly (0.71);
Rainfall Estimation Bias (worst -> best mm)
SON (+80) -> JJA (-80) -> MAM (-20) -> DJF (0)
Interior (+) -> Seashore (-)
Convection (+) -> stratiform (-);
CSI > 0.9 April -> September (>200 mm);
CSI < 0.8 January -> December (<150 mm);
