DESCRIPTION
The heat index program calculates the heat index from the specified temperature and dewpoint. If temp and dewpoint are not specified, the program first displays a heat index chart and then prompts the user for a temperature value in F and an associated dewpoint in F. From this information, the heat index is calculated. The heat index is relatively meaningless for temperatures less than 65F, since the skin loses more heat than it produces below this temperature. Also, the heat index is meaningless for dewpoints less than 65F, since the drier air leads to evaporative cooling of the skin's surface. A second index called the temperature-humidity index is calculated for comparison and a textual heat stress condition such as normal, low, medium, high or extreme is displayed. For example:
heat 90 70 Temperature (F): 90.0 Dewpoint (F): 70.0 Heat Index (F): 95.4 Temperature-Humidity Index (F): 81.0 High
Or to plot a table:
