There's some background at http://en.wikipedia.org/wiki/Heat_index, which is hopefully correct. <br /><br />There is something called the "wet bulb globe temperature" that was developed by the military in an attempt to integrate temperature, wind, humidity, and solar radiation effects on humans.

My experience is that the sun here in Utah feels scorching relative to back east.tcruickshttps://www.blogger.com/profile/06730530603038741779noreply@blogger.comtag:blogger.com,1999:blog-6168620747792092240.post-57281234072928686462012-07-10T10:58:59.189-06:002012-07-10T10:58:59.189-06:00It also seems like the heat index does not account...It also seems like the heat index does not account well for high levels of physical activity. According to the heat index calculator on the NOAA site, (http://www.hpc.ncep.noaa.gov/html/heatindex.shtml) a temperature of 77F with a dew point of 75 yields a heat index of 79, as does a temperature of 83F with a dew point of 0F (extremely dry). However, if you have gone outside for a run in both of these scenarios, you can recognize right away that one of these situations (the dry one) is far more tolerable than the other. On the other hand, if you are sitting in the shade, your comfort level might be nearly identical between these two scenarios.Davidhttps://www.blogger.com/profile/02814313368731066590noreply@blogger.comtag:blogger.com,1999:blog-6168620747792092240.post-7553599387451914012012-07-10T10:54:48.706-06:002012-07-10T10:54:48.706-06:00My roommates were asking about this so I did a qui...My roommates were asking about this so I did a quick wiki search on how the heat index was estimated. I enjoyed reading on the 172 degree F day.<br /><br />"However, in Dhahran, Saudi Arabia on July 8, 2003, the dewpoint was 35 °C (95 °F) while the temperature was 42 °C (108 °F), resulting in a heat index of 78 °C (172 °F). This is comparable to the temperatures that are recommended to kill bacteria in many meat products, and it is common in a sauna."Anonymousnoreply@blogger.com
