I'm somewhat confused by wet-bulb calculations. Here [1] is a calculator for converting temperature+humidity to approximate wet bulb temps. Today's weather forecast in Houston is a high of 38 with a humidity of 85%. [2] That's an approximate wet-bulb temp of 35.66? This article, among a slew of others, are now claiming that's supposed to be lethal? I mean it's uncomfortable, but you're not going to die in that weather in 6 hours. Depending on the season that's a perfectly normal day in many parts of South Asia, and that's been the case for decades. So, what gives? My first assumption is that the calculator was broken, but another one [3] gave an identical figure. --- [1] - https://www.calctool.org/atmospheric-thermodynamics/wet-bulb https://www.calctool.org/atmospheric-thermodynamics/wet-bulb [2] - https://openweathermap.org/city/4699066 https://openweathermap.org/city/4699066 [3] - https://physicscalc.com/physics/wet-bulb-calculator/ https://physicscalc.com/physics/wet-bulb-calculator/
