Low-humidity is a term used to describe an environment with very little moisture in the air. It is often associated with ARID climates, which are characterized by low levels of precipitation and high temperatures. The term 'ARID' is used to describe such climates and is derived from the Latin word for 'DRY'. Low-humidity environments can be found in many parts of the world, including deserts, steppes, and other areas with low rainfall.
