1 You Can’t See It, But You Know It’s There… How Do We Measure Weather?

2 Why We Need Weather Data  Weather data is complied and used to understand the climate of an area to show any trends in weather patterns.  Temperature and rainfall data throughout the year can indicate the type of climate.  Weather data is complied and used to understand the climate of an area to show any trends in weather patterns.  Temperature and rainfall data throughout the year can indicate the type of climate.

3 Weather Tools  There are certain tools we can use to measure weather.  Are you ready to see them?  There are certain tools we can use to measure weather.  Are you ready to see them?

4 Thermometer  A thermometer is a device that measures the temperature of things. The name is made up of two smaller words: "Thermo" means heat and "meter" means to measure. You can use a thermometer to tell the temperature outside or inside your house, inside your oven, even the temperature of your body if you're sick.

5 Anemometer  An anemometer is a device that is used for measuring wind speed, and is one instrument used in a weather station. The term is derived from the Greek word anemos, meaning wind. The first anemometer was invented by Leon Battista Alberti.weather station  An anemometer is a device that is used for measuring wind speed, and is one instrument used in a weather station.

6 Wind Vane  Knowing the direction of the wind is an important part of predicting weather because wind brings us our weather. A wind vane, also called a weather vane, is a tool for measuring wind direction and was probably one of the first weather instruments ever used. To determine wind direction, a wind vane spins and points in the direction from which the wind is coming and generally has two parts, or ends: one that is usually shaped like an arrow and turns into the wind and one end that is wider so that it catches the breeze. The arrow will point to the direction the wind is blowing

7 Hygrometer  A hygrometer is an instrument used to measure relative humidity. Relative humidity is a measure of how much water the air is holding, compared to the maximum amount of water the air could possibly hold at a given temperature.

8 Barometer  A barometer is an instrument used to measure atmospheric pressure. It can measure the pressure made by the atmosphere by using water, air, or mercury. Pressure tendency can forecast short term changes in the weather.atmospheric pressurewaterair mercury  A barometer is an instrument used to measure atmospheric pressure.

9 Rain Gauge  A rain gauge (also known as a udometer or a pluviometer [fluviograph] or a cup) is a type of instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation (as opposed to solid precipitation that is measured by a snow gauge) over a set period of time.meteorologistshydrologistsprecipitationsnow gauge  A rain gauge (also known as a udometer or a pluviometer [fluviograph] or a cup) is a type of instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation (as opposed to solid precipitation that is measured by a snow gauge) over a set period of time.meteorologistshydrologistsprecipitationsnow gauge
