Meteorology is the scientific study of the atmosphere that mainly focuses on weather processes and forecasting. Meteorological phenomena are observable weather events which light up and are explained by the science of meteorology. Those events are bound by the variables that exist in Earth's atmosphere. They are temperature, pressure, water vapor, and the gradients and relations of each variable, and how they change in time. The majority of Earth's observed weather is situated in the troposphere.

Meteorology, climatology, atmospheric physics, and atmospheric chemistry are sub-disciplines of the atmospheric sciences. Meteorology and hydrology comprise the interdisciplinary field of hydrometeorology. Although the term meteorology is used today to explain a sub discipline of the atmospheric sciences, Aristotle's work is more general. The work touches upon much of what is known as the earth sciences. In his own words: All the affections we may call common to air and water, and the kinds and parts of the earth and the affections of its parts. One of the most impressive achievements in Meteorology is his description of what is now known as the hydrologic cycle.

Now the sun, moving as it does, the set up processes of change and becoming and decay, and by its agency the finest and sweetest water is every day carried up and is dissolved into vapor and rises to the upper region, where it is condensed again by the cold and so returns to the earth.
