climatologist

The word 'climatologist' is a modern scientific formation built upon the ancient Greek concept of klima, which originally referred to a zone or region of the earth defined by its inclination or latitude. The suffix -logist, derived from logos (meaning study or discourse), was attached via a connective vowel to create a term for a practitioner of a science. Thus, the term logically constructs the meaning "one who studies the zones or regions of the earth's weather patterns." It entered English in the 19th century as the systematic study of climate developed into a distinct scientific discipline, evolving from a general geographical concept to a precise field analyzing atmospheric conditions over time.
