Dear Tom,

What is the derivation of the word “meteorology”?

Allen White

Dear Allen,

The word meteorology probably originated with the Greek philosopher Aristotle (384-322 B.C.), who wrote and taught on a wide variety of topics that included poetry, ethics and politics.

Aristotle was especially interested in the physical world, and in 340 B.C. he presented a series of treatises on atmospheric phenomena that he observed around him: rain, wind, lightning, thunder, etc.

Aristotle’s explanations were incorrect, but his treatises established meteorology as a distinct discipline and their title, “Meteorologica,” gave the science of the atmosphere its name. The Greeks referred to any particles suspended in the air or falling from the atmosphere as “meteors.”
