Meteorological satellite data from 1982 to 1990 were used to identify areas of significant association between tropical Pacific sea surface temperature (SST) and remotely sensed normalized difference vegetation index (NDVI) anomalies, here taken as a surrogate for rainfall anomalies. During this period, large areas of arid and semi-arid Africa, Australia and South America experienced NDVI anoma...

The arid zone encompasses land that has an imbalance between precipitation and losses through evaporation. Globally, arid zones comprise large part of many countries in the mid-latitudes in both the Northern and the Southern hemispheres. Both Australia and Iran are countries with a large arid zone. This negative water balance in the arid zone affects the type of land use in these countries. At ...
