Definition
The science that studies the Earth's atmosphere and the processes within it that produce weather, including temperature, pressure, moisture, wind, and the interactions between them.
Plain English
The study of the atmosphere and how weather is formed.
Context Anchor
Pilots encounter meteorology during weather study, preflight planning, flight training, and decisions about whether a flight can be made safely.
Derivation
From the Greek meteoron, meaning 'something high in the sky,' and -logy, meaning 'the study of.' Originally the Greeks used 'meteor' for anything seen in the sky -- clouds, rain, lightning, even shooting stars. The aviation use kept the original sense: the study of what happens in the atmosphere above us.
Why Pilots Care
Understanding meteorology lets pilots anticipate hazards such as turbulence, icing, thunderstorms, and low ceilings so they can choose safe routes, altitudes, and departure times.
Intuition Check
Meteorology does not mean only reading a weather forecast. It means understanding weather and the air processes behind it well enough to make safe flight decisions.
Example Sentence 1
A solid grounding in meteorology helps a pilot interpret a weather briefing rather than just read it.
Example Sentence 2
Strong knowledge of meteorology helped the student interpret the frontal passage and decide to delay departure until conditions improved.
