By: Aliyah Hawkins Introduction In this slide show, you will learn about 6 weather tools. Those 6 tools are called a Thermometer, a Barometer, an Anemometer, a Rain Gauge, a Weather Vane, and a Hygrometer. At the end of this power point, you will have a better understanding of the tools a meteorologist will use to study the forecast. Thermometer A thermometer is an instrument that measures temperature. When the temperature in the air changes, it can be measured by a thermometer. There are 2 ways you can measure temperature, Celsius and Fahrenheit. Thermometers can also be used in two different ways. One way is measuring the temperature outdoors or indoors and the second way is measuring your body temperature. An anemometer is an instrument that measures the speed of wind. An anemometer has these little cups that help measure the wind. The stronger the wind gets the faster the cups move. The speed is measured by a cup anemometer, an instrument with three or four small hollow metal hemispheres set so that they catch wind. Barometer A barometer is a instrument that measure air pressure. The centers of storms are areas of relatively low air pressure, compared to pressures around the storm. High air pressure generally bring good weather. Keeping track of how the pressure is changing is important for forecasting the weather. Weather Vane A weather vane is an instrument that shows the direction the wind is blowing. For example, if the wind was blowing from the east then the weather vane would point near east. A weather vane is a very important tool to use when you are trying to track down storms. A meteorologist can say there are high winds coming from a specific direction so I'm going warn these people. As you can see a weather vane is very important. Anemometer Rain Gauge A rain gauge is an instrument that measures precipitation. A rain gauge is a very important tool. If it rained for ten minutes, the meteorologist can check the rainfall and provide a prediction of the weather. This information can be shared with the people at home so they can dress accordingly. A rain gauge is a very important tool used too measure precipitation. Hygrometer A hygrometer is an instrument that measures water in the air. The more water in the air, the more humid and sticky it is outside. Humidity measurement instruments usually rely on measurements of some other quantity such as temperature, pressure, and mass. Another definition for a hygrometer is an instrument that measures the relative humidity of air. So basically a hygrometer measures the humidity in the air. Resources www.wikiapedia.com
