Meteorology is a subset of the atmospheric sciences (which also includes atmospheric chemistry and physics) that focuses on weather forecasting. The science of meteorology extends back millennia, but it was not until the 18th century that considerable progress was made. Meteorology is the science of studying the atmosphere and its motions on short time intervals. Meteorology, also known as 'weather,' is the study of atmospheric variables that affect current or near-future circumstances. Temperature, humidity, precipitation amount and kind, wind direction and strength, atmospheric pressure, and cloud cover are all weather factors that describe the atmosphere. Microscale, mesoscale, and macroscale are three key spatiotemporal scales that explain atmospheric circulation systems and fields of study (including synoptic and planetary scale motions). Meteorology has evolved into a physics-based subject with a wide range of specialisations and increasingly stringent professional requirements. A meteorologist is a scientist who utilises scientific concepts to explain, comprehend, observe, and forecast atmospheric occurrences and/or how the atmosphere impacts the world and life on the planet.
