Forecasting The Weather Part 2 Stormy Chilly! Sunny

What is a Forecast?

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.

Thermometer They are instruments that measure or indicate temperature Measured in degrees Celsius or Fahrenheit

Station Model

Doppler: Used to track precipitation/severe storms 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 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
