Meteorologists are scientists who study the causes of weather and try to predict it. Meteorologists collect and interpret data from a variety of sources in order to predict the weather. These sources include local weather observers, instruments carried by weather balloons and satellites, and weather stations around the world. Radar is used to find the location, movement, and intensity of precipitation. Meteorologists use maps, charts, and computers to analyze weather data. In the United States, the National Weather Service (NWS) and the National Oceanic and Atmospheric Administration (NOAA) collect and analyze weather data.
