Today’s Weatheris brought to you
by Westly Whithers
Westly Whithershere to give you the latest
aboutour weather.
First, you need to know a little about me and how I make my predictions.
• Scientists who studies and measures weather conditions.
Some call me a weatherman but I went to school to learn more and became a ………
• Need to know how to use and read the following instruments:
Thermometer
• measures air temperature
Hot Fact1593 Galileo Galilei invented the 1st
Thermometer (on the left). Then in 1714 Gabriel Fahrenheit invented the 1st mercury thermometer with a F° scale. In 1743 Andrus Celsius created a thermometer with the Celsius scale.
Galileo’s Thermometer
Barometer
• measures pressure of the atmosphere
(air pressure)
Hot Fact- Evangelista Torricelliinvented the mercury barometer in 1644.
Anemometer • measures wind speed
Hot Fact- Measures wind in revolutions per minute.Aircraft crews need to know the speed of the wind before taking off and landing.
Weather Vane or Windsock • finds the wind’s
direction
Hot Facts -The first metal wind vane was a Life-size Greek God, Triton, that was placed in Athens between 48 BC to 250 AD (This vane of Triton represented him traditionally with a human head and upper body and the tail of a fish. He also held a wand in his hand pointing the direction from which the
wind blew.)
Rain Gauge
• measures the amount of liquid precipitation over a period of time
Hot Fact- In 1441 King Sejong and his son invented the first rain gauge used as the official tool to assess land taxes based on farmer’s potential harvest.
