When the weather man tells you it's going to rain today, he is giving a meteorology report, or weather forecast. Meteorology is the study of our atmosphere.
Meteorology comes from the Greek meteōrologia meaning "of the atmosphere." While meteorology involves various branches including aviation and agricultural studies, most commonly we see it in our everyday lives through weather forecasting, a process that involves collecting data about an atmosphere to determine what the weather will be. If you're fascinated by storms and hurricanes, consider a career in meteorology.
