FIGURE E3. Anomalous precipitation (mm, top) and
precipitation percentiles based on a Gamma distribution fit to the
1979–2000 base period data (bottom) for MAR 2006. Data are obtained
from a merge of raingauge observations and satellite-derived
precipitation estimates (Janowiak and Xie 1999, J. Climate, 12,
3335–3342). Contours are drawn at 200, 100, 50, 25, -25, -50, -100,
and -200 mm in top panel. Percentiles are not plotted in regions where
mean monthly precipitation is <5mm/month.
