Applications for such permission, with a statement of the purpose and extent of the Figure 3.2: The world map of annual mean aerosol index (Ai) values (x10) determined Figure 3.4: Annual mean frequency distribution of dust storms using four indicators: drainage basins in arid areas, due to the wind-erodible. Process Step. Process Description Based on the overlay of 4 raster layers: annual precipitation, annual potential evapotranspiration, mean temperature of the coldest and mean temperature of the warmest month. The classes follow the UNESCO system used in their map of the arid regions of the world (see cross-reference), extended introducing the 'per-humid' class (aridity index >1).
