There are three ways to measure relative humidity. Current automated weather systems measure the reflection of a beam of light on a mirror. The mirror is chilled until atmospheric moisture condenses ...

When referring to the mugginess of the air, meteorologists will point to dew point rather than relative humidity. Relative humidity is indeed a measure of how much moisture is in the air relative to ...

Relative humidity has been used to describe moisture levels in the atmosphere for so long that it has become the most common (though often misunderstood) moisture measurement. And there is truth to ...

My high school had a weather station on the roof so earth-science students could make measurements each morning. We climbed up a ladder in the janitor's closet, went through a hatch and out onto the ...

Dew point can be calculated using the air temperature and a relative humidity value, which is measured using something called a sling psychrometer. A psychrometer is a metal rod, around 6 inches long, ...

If you get your current weather information in the morning, you should know that the morning relative humidity is not a useful indicator of how humid the weather will be today. In fact, the relative ...

Have you ever traveled to a different city with the same temperature as your initial place, but the new city feels significantly different in terms of temperature? That's because these places have ...

Engineers now have two multifunctional transmitters at their fingertips for measuring relative humidity and temperature. The HT737 is a digital unit that measures relative humidity, temperature, dew ...
