.5 days, which gave the high and low CDD split at 75 days. Meanwhile, the median of mesic CDD was 24.5 days and the distinction between high and low CDD was 25 days ( Table 2 ). Table 2. Summary of high and low SDII and CDD classifications. CDD and SDII were also normalized to minimize the site-to-site bias of longer CDD periods or inherently higher SDII values associated with different precipitation regimes. CDD and SDII were normalized with the mean and , and the standard deviation and from

and the region has a unimodal rainfall regime dominated by the migration of the intertropical convergence zone (ITCZ) and at the southern extent of the domain, the West African monsoon. Fig . 1. Dominant land-cover types in the West African Sudano-Sahel from the UMD Global Land Cover Classification. Isohyets, at 250-mm increments, represent total annual rainfall ranging from 250 mm in the north to 1250 mm in the south. Because of its low vegetation density, lack of rainfall gauges, and widespread
