I comment from time to time on how the dew point temperature can be a good guide as to what the coming overnight low temperature might be. A reader wonders if there is such a relationship for relative ...

Air pollution is not taken into consideration. Actually, relative humidity is not directly measured. The air temperature and dew point temperature are measured, and the relative humidity is then ...

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 ...

An e-mail from Herman asks about an instrument using thermometers to determine humidity and wants to know what it is. It's called a sling psychrometer and consists of two thermometers fastened onto a ...

YOUNGSTOWN, Ohio (WKBN) – There might not be a more misunderstood phrase in meteorology than “relative humidity.” Every summer when humidity returns, this phrase echoes across the United States: “It ...

(WHTM) — When temperatures rise, sometimes the air can feel dry and comfortable. But, sometimes it can feel downright tropical outside. This is caused by moisture in the air and it makes the air ...

The hygrometer is the instrument that measures relative humidity, the humidity is relative to the air temperature. This can confuse people because if you hold the ACTUAL water vapor constant but heat ...

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

Across much of the world, hotter days are no longer arriving alone. The air itself is changing, sometimes turning from dry ...

An AC bridge circuit can be used to measure the unknown capacitance of a sensor, such as a relative humidity (RH) sensor. Some RH sensors have a transfer function of capacitance vs %RH. Usually the ...
