Hygrometer

Hygrometer•Used to measure moisture content •Measures the humidity of any gas such as air•Francesco Folli invented the more practical hygrometer in1664•Some hygrometers use hair to determine moisture content•They are sometimes used in incubators•Leonardo da Vinci developed the first hygrometer in the 1400s

Thermometer

ThermometerGalileo Galilei is one of the inventorsUsed to measure air temperatureIs a closed glass tube with a scale(s)Mercury or alcohol are sometimes the liquid in the thermometerExperiented on in 1610Not always used for weather

Barometer

BarometerMeasures air pressure Designed by TorricelliFirst built in 1643Low pressure usually means rain is comingHigh pressure usually means clear skiesBarographs record the data found on the barometer

Weather Balloons

Weather BalloonsWas invented in the late 1800s Are similar to the originalsThey were invented to store weather dataWeigh about 2.2 poundsAre similar looking to a hot air balloonRise more than 15 miles while collecting data

Anemometer

AnemometerLeon Battista Alberti invented itInvented in 1450Records the revolutions of the cups and calculated the wind velocityCan be divided into two classesVery similar to the first invented oneAnemos is a Greek word that means wind

Weather Satellite

Weather SatelliteSuccessfully launched on April 1, 1960Was televised from spaceWeighs 270 poundsFunctioned for only 78 days(total)Sends thousands of pictures to EarthUsed to monitor the weather and climate of earth

Weather Radar

Weather RadarShows where precipitation is occurring and how hard its fallingSends out pulses of microwave energyThe energy reflects of raindrops or snowflakesMore that 100 government run weather radarsVery useful for predicting storms

Weather Map

Weather Map

Displays meteorological features across a particular areaHave been in use since the mid-19th centuryHelp locate weather frontsCan show where jet streams are located

Rain Curtain

Rain CurtainPatent issued in 1995Pocket portableHas an inflatable ring capHand free protectionGives customers their own spaceSheer shower curtain wallsAlternative to the bulky umbrella
