The "combined" Normalized Difference
Vegetation Index (NDVI - NDVI) image shows Sea Surface Temperature (SST)
anomalies (around) and NDVI (for) Africa during January 2000. The upper
part of the legend shows SST anomalies (Blues are -ve SST departures, reds
are +ve SST departures). As you can note there is a large pool of warm
water off the coast of Southern Africa on the order of +1.0 to + 2..0 deg.
C above normal) even off the coast off Namibia where the cold upwelling
Bangeula current is usually dominant. These conditions began to develop
way back in November and to a large extent account for the recent heavy
rains over the region. The lower end of the legend shows NDVI anomalies
for the same time period.
