No....LB The dewpoint temperature is the temperature at which the air can no longer "hold" all of the water vapor which is mixed with it, and some of the water vapor must condense into liquid water. The dew point is always lower than (or equal to) the air temperature Current conditions at New York City, Central Park (KNYC) Lat: 40.78°NLon: 73.97°WElev: 154ft.

So the wet bulb only equals the dew point when the relative humidity is 100%, at which point they both intersect with the actual temperature! wait, I reread the definition for wet bulb you posted and it is also always either equal to or lower than the actual temp? can wet bulb be used in place of dew point for heat index calculations?

The most accidents happen in low snowfall totals (under 1") and in icy conditions. 1 Link to comment Share on other sites More sharing options...
