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

inventors

Used to measure air temperature

Is a closed glass tube with a

scale(s)

Mercury or alcohol are sometimes

the liquid in the thermometer

Experiented on in 1610

Not always used for weather

Barometer

BarometerMeasures air pressure

Designed by Torricelli

First built in 1643

Low pressure usually means rain is

coming

High pressure usually means clear skies

Barographs record the data found on the

barometer

Weather Balloons

Weather Balloons

Was invented in the late 1800s

Are similar to the originals

They were invented to store weather data

Weigh about 2.2 pounds

Are similar looking to a hot air balloon

Rise more than 15 miles while collecting

data

Anemometer

Anemometer

Leon Battista Alberti invented it

Invented in 1450

Records the revolutions of the cups

and calculated the wind velocity

Can be divided into two classes

Very similar to the first invented one

Anemos is a Greek word that means

wind

Weather Satellite

Weather SatelliteSuccessfully launched on April 1,

1960

Was televised from space

Weighs 270 pounds

Functioned for only 78 days(total)

Sends thousands of pictures to

Earth

Used to monitor the weather and

climate of earth

Weather Radar

Weather RadarShows where precipitation is

occurring and how hard its falling

Sends out pulses of microwave

energy

The energy reflects of raindrops or

snowflakes

More that 100 government run

weather radars

Very useful for predicting storms

Weather Map

Weather Map

Displays meteorological features across a

particular area

Have been in use since the mid-19th

century

Help locate weather fronts

Can show where jet streams are located

Rain Curtain

Rain CurtainPatent issued in 1995

Pocket portable

Has an inflatable ring cap

Hand free protection

Gives customers their own

space

Sheer shower curtain

walls

Alternative to the bulky

umbrella
