Weather is defined as the condition of the atmosphere at a given time and place. Scientists use tools like thermometers, barometers, rain gauges and anemometers to measure conditions and predict tomorrow's weather. Meteorologists are scientists who study weather and its elements, which include air temperature, pressure, humidity, precipitation, clouds, fog and wind.
