One of my twitter followers asked me the other day if I can tweet about the difference between dew point and relative humidity. While I can certainly be succinct when I need to, I am not sure 140 ...

The Hindu explains the concept of relative humidity, why it matters, what it implies physically, how to measure it, and why the wet-bulb temperature matter. Subscribe now to read the full explainer.

Comparison As noted earlier, when looking at relative humidity, Alaska is the most humid state. This is a function of the low temperatures. A cold airmass simply cannot hold a lot of moisture.

To determine relative humidity subtract the lower “wet bulb” temperature from the higher “dry bulb” temperature to determine the difference and compare to the chart.

Relative humidity is a much more variable, much less reliable gauge of comfort because it is, well, relative to temperature. When the air's temperature matches its dew point temperature, relative ...

The relative humidity is useful in predicting fire danger. Typically, with higher winds and relative humidity lower than 25 percent, you are nearing critical fire danger.

A daily mismatch between temperature and humidity, observed in certain mountain and waterside regions, helps regulate ...

Sometimes the temperature outside feels warmer than it is, and there's a reason. Here's a breakdown of the heat index.

Heat index chart - temperature and relative humidity (WOWT) As you can see from the chart above, with a steady temperature of 90°, the heat index rises to 95° at a relative humidity of 50%.

You just need to know the air temperature and the relative humidity, and the chart will tell you the rest. Is the heat index calculation the same for everyone? Not quite, but it’s close.
