Weather Vocabulary

•  Atmosphere – air that surrounds the Earth; made of a mixture of gases    

•  Meteorologist – a scientist who studies the weather  

• Precipitation – water that falls to the Earth’s surface as rain, snow, sleet, or hail

• Rain gauge – a tool for collecting and measuring the amount of precipitation that falls

•  Temperature – a way of measuring how hot or cold something is; temperature is measured using either the Fahrenheit (F) or Celsius (C) scale

•  Weather – day-to-day condition of the atmosphere in an area; weather has short-term variations (minutes to weeks)

• Wind vane – a weather instrument used to show the direction of the wind; often ornamental

Temperature

• Temperature is measured using a thermometer. There are different scales and standards for measuring temperature including Celsius, Fahrenheit, and Kelvin.

• There are three main temperature scales that are used today:

• Celsius - The most common temperature scale in the world is Celsius. Celsius uses the unit "degrees" and is abbreviated as °C. The scale sets the freezing point of water at 0 °C and the boiling point of water at 100 °C

• Fahrenheit - The temperature scale most common in the United States is the Fahrenheit scale. Fahrenheit sets the freezing point of water at 32 °F and the boiling point at 212 °F.

• Kelvin - The standard unit of temperature that is most used by scientists is Kelvin.
