Estimated potential woody vegetation cover and vegetation sensitivity to climate. The surface (A) representing the 99th quantile of woody vegetation cover (Fpot) as a function of mean wet season precipitation (Pw) and mean rainfall depth during the wet season [αw (mm)]. The local slope of the 99th quantile surface is calculated along both axes, normalized, then combined to form an index (B) of vegetation sensitivity to climate fluctuations (Vsen).
