RE: Differences between Heat Index, Dew Point and Wet Bulb Temperature charnott (Civil/Environmental) 17 Jul 13 06:05 heat index can also refer to lcoal or regional index relationships. Temperature & Dew Point The ‘Heat Index’ is a measure of how hot weather "feels" to the body. If you would like to calculate the wind chill index for combinations of temperature and wind other than those given in the table above, you can use the following formula: WC = 91.4 - (0.474677 - 0.020425 * V + 0.303107 * SQRT(V)) * (91.4 - T) This new value is considered to be the heat index. Printable Charts: Temperature to Heat Index. Sets   Books    *   Airplane Performance Computers, Wind speeds above 40 mph have little additional chilling Also, explore the wind chill and dew point calculators, as well as hundreds of other calculators. While both the humidex and the heat index are calculated using dew point, the humidex uses a dew point of 7 °C (45 °F) as a base, whereas the heat index uses a dew point base of 14 °C (57 °F). For example, if the air temperature outside is 65°F and the dew point temperature is … While the WBGT and Heat Index both attempt to describe how "hot" it is and the potential for heat related stresses, they go about it in different ways. There is a close relationship between dew point and relative humidity (RH), the latter of which is the ratio of the water vapor pressure in an air parcel to the saturation pressure of the water vapor in that same parcel at a specific temperature. Sp, a low dew point is dry and a high dew point is considered moist. This new value is considered to be the heat index. *    Atlases   For example, on the chart, if the temperature is 92° and the dew point … * Museums  *  ToolsRC In a particular case, when the air is maximally saturated with water (the relative humidity is 100%), the dew point is equal to the current temperature. *    Real Sports Cars for *    GPS   This table uses relative humidity and air temperature to produce the "apparent temperature" or the temperature the body "feels". Below is a chart of some these values: Photo courtesy of NOAA. But there is a cool nugget of info that falls out of this. The knowledge of only two of these values is enough to determine the state of the moist air - including the content of water vapor and the sensible and latent energy (enthalpy) in the air. The number which appears at the intersection of the temperature and either the humidity on the left or the dewpoint on the left, is the heat index. In general, a dewpoint of 60 - 63°F begins to “feel” more humid, and a dewpoint of 70°F or higher becomes rather oppressive on a summer day. This implied wet-bulb temperatures of about 33.5 °C (92.3 °F) and 34.7 °C (94.5 °F) respectively. Calendars   *  Jet Fighter Models  *   Flight Dew point is the temperature at which the vapor in the air would condense into liquid. The dew point. Both measurements are a function of moisture so it’s easy to get the two confused or think that they’re interchangeable. When using Dew Point as a guideline, use this chart to calculate how much to adjust your pace Although El Helou et al. Exposure to full sunshine can increase heat index values by up to 15°F.
