They got the dewpoint next to the air temperature and the fog rolled into the remaining wet spots.

These nuclei are so effective that condensation can occur even before the dewpoint is reached.

In July or August, the dewpoint rises dramatically for a brief period.

Its purpose is to provide a standardised environment in which to measure temperature, humidity, dewpoint and atmospheric pressure.

Warmer air is cooled below its dewpoint and the excess water vapor condenses.

Chilled mirror dewpoint hygrometers are some of the most precise instruments commonly available.

High dewpoint (humidity) conditions decrease the cooling capability of the evaporative cooler.

The potential for convection in the atmosphere is often measured by an atmospheric temperature/dewpoint profile with height.

Outside the United States, temperature and dewpoint are plotted in degrees Celsius.

The water vapor cools and at the dewpoint it condenses and fog forms.

In my opinion, it would better for your wallet and the environment for you to keep the whole house heated and therefore above dewpoint temperature.

Where exactly the dewpoint will fall in (or out) of those thickened walls-and in what climate zone-becomes crucial.

Calculated Dewpoint:

Clouds form when the dewpoint of water is reached in the presence of condensation nuclei in the troposphere.

For a given dewpoint and its corresponding absolute humidity, the relative humidity will change inversely, albeit nonlinearly, with the temperature.

As the temperature is cooled to the dewpoint, water vapor condenses upon available cloud condensation nuclei, and forms a cloud.

Viewers craving to know about conditions in Fenwick Island, Del., or what the dewpoint was at any moment had the Weather Channel on call.

Can be roughly approximated by taking the spread between the surface temperature and dewpoint and dividing by 4.4 (Celsius), then multiplying the result by 1000.

There's a pretty sharp divide in average dewpoint temperature right along that longitude in the summer, with much higher dewpoints across most of the eastern United States.

Twister is able to dehydrate to typical pipeline dewpoint specifications and relies on a pressure drop from the inlet of about 25%, dependent on the performance required.

Despite this, METAR reports from the United States also report the temperature (and dewpoint, see below) in degrees Celsius.

Because weather reports usually contain the dewpoint and relative humidity, but not the wet bulb temperature, a Psychrometric chart must be used to identify the wet bulb temperature.

When the marine layer encounters the colder waters along the California coast, it cools to its dewpoint, and if small particles called condensation nuclei are present, liquid water drops will form.

Compressed air from a trompe is at the temperature of the water, and its partial pressure of water vapor is that of the dewpoint of the water's temperature.

Two degrees drop in the temperature would mean that the air above the surface of the floe would achieve dewpoint, that point on the scale where freezing fog would begin to form.
