# Difference between revisions of "Talk:2026: Heat Index"

Look at the formula, then at the table and try to tell with straight face that those tables were computed from the formulae and not the other way around. -- Hkmaly (talk) 22:38, 30 July 2018 (UTC)

The Wikipedia page explicitely says that the various formulaes try to approximate the table. Can't be more explicit. 172.69.226.119 06:36, 31 July 2018 (UTC)

What confuses me is that even at 40% humidity the heat index is a lot hotter than the actual temperature. If 110 degrees at the lowest humidity that occurs commonly feels like 130 degrees, then what does it mean to feel like 110 degrees?Probably not Douglas Hofstadter (talk) 15:46, 31 July 2018 (UTC)

40% humidity is not a common level for places that typically reach 110f. For Phoenix, AZ, one of the few places that can reach both 110f and 40% humidity during the North American Monsoon, which is a small fraction of the summer, this is dealt with by nearly every indoor area being air conditioned, both to cool the air and to remove humidity. So, what it means for the "typical" 110f is what it feels like standing in front of your oven, rather than in front of a dishwasher on the drying cycle. And yes, 110 and 40% humidity is a severe weather event, and the National Weather Service routinely issues heat advisories and warnings in July and August. 172.68.47.36 23:59, 22 August 2018 (UTC)

Ironically, it is actually when humidity is at 100% (your sweat can't evaporate) that you feel the actual temperature. The lower humidity makes you feel cooler than the actual temperature. Similarly the windier it is (in cold weather) the more body heat is removed and the closer the actual temperature is to what it feels like. 162.158.62.141 21:31, 2 August 2018 (UTC)

I don't think it's accurate that "Human skin does not directly detect temperature - only the rate of heat gain or loss." Isn't it more that skin temperature is a dynamic equilibrium between the body's internal temperature and heat loss? I.e., skin feels colder in cold water than cold air because its equilibrium temperature is lower with faster heat loss? Also, is skin temperature even relevant here, or is it more about core temperature? JohnWhoIsNotABot (talk) 18:11, 3 August 2018 (UTC)

Could "add a few more degrees" be a pun on degrees of freedom, i.e. adding more variables to a meteorologist's model for heat index until it matches human perception closely enough? --172.68.133.180 22:23, 30 August 2018 (UTC)

I agree that "add a few more degrees" is a pun, since that "WAY" is capitaled and can be interpretated as dimension in a table. ( a two-way table or three-way table means that the table has 2 or 3 degrees of freedom) send by Temporal 162.158.94.164 03:36, 2 June 2021 (UTC)
