Ohio and Kentucky were among 18 states that experienced record-breaking humidity in July. Here's why it has been so humid ...

All three — relative humidity, temperature and dew point — are bound together in the mathematical relationship below. A source of confusion Relative humidity changes when temperatures change.

When the atmospheric moisture content (i.e. relative humidity) is high, the rate of evaporation from the body decreases.” ...

Using relative humidity is deceiving when talking about how humid is outside because it is dependent on air temperature. Dew point is the better option.

Referring to the dew point to describe how the air feels or how much moisture is present is more appropriate because relative humidity fluctuates rapidly from temperature changes.

Dew point/relative humidity questions come up fairly often and this is a good one. Water vapor in the atmosphere is pretty important for deep-sky observing and photography. The atmosphere can only ...

Explore>> Could Niagara Falls completely freeze? Relative humidity is calculated using meteorological variables such as vapor pressure, saturation vapor pressure, temperature and dew point.

Another example would be in the winter. If the air temperature were 45 degrees and the dewpoint were 40 degrees, you're dealing with 85% relative humidity. That sounds really steamy!
