Forecast Map Weather Balloons • These instruments are carried aloft by hydrogen filled balloons to measure and simultaneously transmit recorded data which include pressure, temperatures and humidity. Anemometer • An instrument used to measure wind speed. • Anemometers find how fast the wind is blowing. Barometer • A weather instrument that is able to measure air pressure or atmospheric pressure Scientific Household Maritime Wind Vane • Wind Vanes indicate the direction a wind is blowing • Must be placed accurately with a compass in the right location! Windsock • Used to collect data about the direction and strength of wind Psychrometer • A psychrometer is an instrument commonly used in laboratories to measure relative humidity. It is also referred to as a wet- and dry-bulb thermometer. Rain Gauge • Rain gauges find & measure precipitation (rain, snow, sleet, or hail) that falls to the Earth's surface. • They are instruments that measure or indicate temperature • Measured in degrees Celsius or Fahrenheit Thermometer Station Model Radar Types • Radar is used to find the location, movement, and amount of precipitation of a given location Doppler: Used to track precipitation/severe storms Satellite: Helps Monitor Weather From Space Vocabulary to Define • Windsock • Wind Vane • Anemometer • Barometer • Rain Gauge •Radar •Station Model •Forecast •Thermometer •Weather Balloon Vocabulary to Define • Meteorology Weather • Tornado Hurricane • Front Air Mass • High Pressure Low Pressure • Forecast • Weather Satellite Vocabulary Concepts • Air Mass – a large boy of air with the same moisture and temperature throughout • Front – the boundary where two air masses meet • Psychrometer (wet/dry bulb thermometer) an instrument commonly used in laboratories to measure relative humidity • Rain Gauge - finds & measure precipitation (rain, snow, sleet, or hail) that falls to the Earth's surface • Station Model – is a small circle that shows the location of a weather station Vocabulary Concepts • Anemometer - An instrument used to measure wind speed. • Barometer - A weather instrument that is able to measure air pressure or atmospheric pressure • Wind Vane- instrument used to indicate wind direction • Wind Sock – an instrument used to collect data about the direction and strength of wind Vocabulary Concepts • Meteorology -the scientific study of Earth’s weather • Weather – the condition of the atmosphere at a certain time; includes temperature, and rainfall • High Pressure – anticyclone, equals low wind and dry clear conditions • Low Pressure = cyclone, high winds, wet stormy conditions • Hurricane – a severe storm that develops over tropical oceans with winds that rotate counter clockwise in the n. hemisphere, surrounding a low pressure center Vocabulary Concepts • Thermometer - instruments that measure or indicate temperature, measured in degrees Fahrenheit or Celsius • Radar - is used to find the location, movement, and amount of precipitation of a given location (Doppler Radar) • Weather Satellites – orbit the Earth and send images of weather systems back to Earth via Doppler Radar (GOES-8) • Tornado – a violent swirling column of air that rotates, moves quickly, and is short lived
