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

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 GaugeRain 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

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

•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
