Glossary of meteorology, via American Meteorological Society website, Oct. 15, 2018 (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. See also atmospheric science; compare climatology. 2. In popular usage, the underlying science of weather and weather forecasting.)
Encyclopædia Britannica online, Oct. 15, 2018 (Atmospheric science: interdisciplinary field of study that combines the components of physics and chemistry that focus on the structure and dynamics of Earth's atmosphere. The atmospheric sciences are traditionally divided into three topical areas--meteorology (the study and forecasting of weather), climatology (the study of long-term atmospheric patterns and their influences), and aeronomy (the study of the physics and chemistry of the upper atmosphere).)
Merriam-Webster dictionary online, Oct. 15, 2018 (meteorology: 1. a science that deals with the atmosphere and its phenomena and especially with weather and weather forecasting. 2. the atmospheric phenomena and weather of a region)
