what does a hygrometer and anemometer do in the weather?


Barry's Response - Brittney:

These things are special instruments for measuring weather:

For instance, a thermometer measures temperature and a barometer measures pressure.

Now for the two you asked about:

What does a hygrometer measure? A hygrometer measures the amount of water vapor in the air, the humidity. Some use a salted metalstrip to display humidity as a function of the differing expansion rates of the two substances. Some use hair because it responds well to moisture changes. Others use electronic circuitry in the form of refrigerated components collecting dew or measurements of changes in electrical capacity, resistance or conductivity. More on hygrometers at http://www.stuffintheair.com/hygrometermakes.html

Anemometers,like the one shown above, measure the wind speed, while a weather vane points out the wind direction for you. Most familiar ones measure wind speed, and others measure changes in pressure to deduce speed. more on wind measurements at http://www.stuffintheair.com/weathervanestore.html

Hygrometer is basically a device that is used to measure the humidity of a particular place. Humidity is basically the moisture content in the air. The olden ways of measuring this was used by metal strips and now we have got electronic apparatus which works with the help of sensors.

Barry's Response - Apparently they used hair in the old days as well.

I did not know that a hygrometer measures humidity. I thought it was very interesting. I would not explore the site more on this topic.

Thanks for the informative article! I love the picture of the anemometer, it looks like something out of an old time science fiction novel. ;) This is a great site, I'll definitely be exploring more of it!
