Aridity

Aridity refers to the dryness of an area, indicating a shortage of moisture. It is typically measured by aridity indices that consider factors such as annual rainfall and temperature, which influence how dry or wet an environment is. Arid regions receive very little rainfall, have high temperatures, and lack sufficient moisture to support lush vegetation. These areas often feature deserts or drylands and are characterized by limited water resources, making them challenging for agriculture and sustaining diverse ecosystems. In essence, aridity describes the degree of dryness in a given landscape, affecting its climate, soil, and living conditions.
