World Map Highlighting Climate Zones

This world map presents a global overview of aridity zones, using color-coded regions to show varying degrees of dryness. It defines hyperarid, arid, semiarid, and dry subhumid areas based on their aridity index (AI/PET) values. You can observe extensive hyperarid regions in deep red, such as the Sahara Desert and parts of the Arabian Peninsula and Australia, transitioning to less arid zones like arid (orange), semiarid (yellow), and dry subhumid (light yellow). Some areas that might be considered drylands are excluded from this particular classification, appearing in dark gray. The map provides a valuable perspective on the distribution of dry climates worldwide.
