What is a meteorology?

From the American Meteorological Society's "Glossary of Meteorology"...

Meteorology

1. The study of the physics, chemistry, and dynamics of the earth's atmosphere, including the related effects at the air–earth boundary over both land and the oceans. Fundamental topics include the composition, structure, and motion of the atmosphere. The goals ascribed to meteorology are the complete understanding and accurate prediction of atmospheric phenomena.

2. In popular usage, the underlying science of weather and weather forecasting.

Meteorologist

- A person who is professionally employed in the study or practice of meteorology.

- It often refers to individuals who have completed the requirements for a college degree in meteorology or atmospheric science.

Meteorology is the study of the atmosphere and its effects on our weather. The atmosphere is the gaseous layer of the physical environment that surrounds a planet. Earth’s atmosphere is roughly 100 to 125 kilometers (65-75 miles) thick. Gravity keeps the atmosphere from expanding much farther.

Meteorology is a subdiscipline of the atmospheric sciences, a term that covers all studies of the atmosphere. A subdiscipline is a specialized field of study within a broader subject or discipline. Climatology and aeronomy are also subdisciplines of the atmospheric sciences. Climatology focuses on how atmospheric changes define and alter the world’s climates. Aeronomy is the study of the upper parts of the atmosphere, where unique chemical and physical processes occur. Meteorology focuses on the lower parts of the atmosphere, primarily the troposphere, where most weather takes place.

Meteorology is the interdisciplinary scientific study of the atmosphere.

Meteorology includes atmospheric chemistry and atmospheric physics with a major focus on weather forecasting.

The word "meteorology" is from Greek μετέωρος metéōros "lofty; high (in the sky)" (from μετα- meta- "above" and ἐωρ eōr "to lift up") and -λογία -logia "-(o)logy".

Study of weather paterns and currents

study of weather.. you couldve googled that :p
