What does aerology mean?
Aerology is the scientific study of the atmosphere, especially the physical properties of air and the phenomena that occur in it. The term can cover atmospheric research more broadly than meteorology, although modern speakers usually use meteorology for the study of weather and related processes. In historical and technical writing, aerology also appears in discussions of air pressure, temperature, density, circulation, and phenomena such as clouds or atmospheric electricity. Because it is a specialized and relatively uncommon word, it is more likely to occur in academic contexts, older scientific literature, or as a title or subject label than in everyday conversation. Its name makes its scope transparent: it combines a root meaning “air” with a suffix meaning “study.” Knowing the distinction can be useful when reading a source that treats atmospheric science as a broader subject than weather forecasting. Aerology is therefore less a decorative synonym for meteorology than a historically and conceptually broader label, though the exact boundary between the two can depend on the writer.

Etymology of aerology
Aerology was formed in 19th-century English from the combining form aero-, derived from Greek aēr, meaning “air,” and -logy, from Greek -logia, meaning “study.” Its relatives aerometer, aeronautics, aerodynamics, and aerobic preserve the same air-root, although they developed in different scientific and biological contexts.

How aerology is actually used
Relatively uncommon and technical. In modern usage, meteorology is more common for the study of weather, while aerology may refer more broadly to atmospheric science and the physical properties of air.
Easily confused with aerology
Meteorology primarily concerns the study of weather and atmospheric processes, whereas aerology can denote the broader scientific study of the atmosphere and the physical properties of air.
