Arid
Arid (/ˈærɪd/; from Latin aridus, meaning "dry, parched") is a term used to describe a dry, desert-like environment with little to no precipitation.
Definition
In meteorology, an arid climate is characterized by a lack of effective rainfall, typically defined as less than 250 mm per year. This can be due to low rainfall, high evaporation rates, or a combination of both.
Etymology
The term arid comes from the Latin word aridus, which means "dry" or "parched". It was first used in English in the 1650s to describe dry lands or deserts.
