People usually associate meteorologists with television station weathercasters. Most meteorologists, though, work behind the scenes. They can be found working for the National Weather Service, in laboratories, at weather research stations, or working for universities. Meteorologists need a good understanding of physics, chemistry, hydrology, and other disciplines to do their jobs well. The American Meteorological Society defines a meteorologist as someone who can research, observe, explain, and forecast the weather; who understands the principles behind weather phenomena; and who appreciates the effects that the weather has on Earth. Meteorologists obtain a bachelor’s degree in science to do their jobs, and many of them have master’s degrees or doctorates. There are also a variety of specialties in the field, such as hydrology and climatology, and many meteorologists study mathematics, computer engineering, electrical engineering, and more.
