What does meteorology mean?
Meteorology is the scientific study of the atmosphere and the weather conditions that occur within it. It examines phenomena such as temperature, humidity, air pressure, clouds, wind, precipitation, and storms, as well as the interactions among them. Meteorologists use observations, satellites, radar, computer models, and atmospheric theory to understand how weather develops and to make forecasts. The subject is important for public safety, aviation, agriculture, transportation, climate research, and many other activities. The word comes from Greek roots associated with the study of things high in the sky, reflecting the long historical connection between this field and observations of the heavens.

Where does meteorology come from?
Meteorology derives from the Greek meteorologia, a term associated with the study of meteōros, meaning phenomena or things occurring high in the sky. The word entered English through Latin and scholarly usage, initially referring broadly to the study of celestial and atmospheric phenomena. Its modern sense became established as the scientific study of the atmosphere and weather, while related English words such as meteor, meteoric, and meteorite continue to reflect the same Greek root.
