Coach Spore DieselThis is now a typical #WetBulb here.

Deutlich besser.
Da noch ein paar Absätze rein und Tags wie #WetBulb drunter und es wäre perfekt.
RustyLMehlbergTHE HEAT IS ON!
The #Heat #Advisory today could be expanded to an #Extreme Heat #Warning for the southern half of the #Northland Friday afternoon and evening. The feel like #temperature could be around 100°, with #wetbulb globe temperatures in the upper half of the 80s.
Overall, the next few days will be handled best with plenty of #water, shade, and rest in cool places.
David J. Atkinson@ai6yr There is high danger of a mass #casualty “wet-bulb event” in Turkey and elsewhere that hit 50 C high temperatures! The chart in the attached picture show the relationship between temperature and relative humidity. Short story: very high temperatures and even moderate humidity will kill you because you can’t cool your body core by perspiration. That’s the red area in the chart. Human physiology varies; that’s why there is a wide yellow line. How long you can survive is also a variable. With the #ClimateCrisis , it is question of when — not if — a #wetbulb catastrophe will occur. Anyone caught without A/C in one of those areas will die if it lasts very long. Is this what will stir people into action? A fictional, but scientifically accurate, depiction of a wet-bulb event is the first chapter in “Ministry of the Future” by Kim Stanley Robinson.
@ai6yr How hot is too hot? A good explainer about #wetbulb temperature.

DqTube@DoomsdaysCW #WetBulb has just a few issues:
1) The name is like something from the Japanese AV industry.
2) The definition is so complex that people who aren't into #STEM can't really imagine it.
3) The conspiracy-minded redneck will tell you that it's like a sauna and you're a snowflake because he once went to a sauna and nothing happened to him.

DoomsdaysCWForget #HeatIndex. #WetBulb Globe Temperature Is Where It’s At.
"One of the most common terms we hear during the summer when discussing the weather is Heat Index. While the Heat Index can give you an idea of how dangerous the heat can be, there is another lesser known variable that may give a complete description, known as the #WetBulbGlobeTemperature.
"The Heat Index is a measure of how hot it feels to the human body, taking into account the temperature and the relative humidity. The higher either one value is, the higher the heat index and the greater the stress exerted on the body. Heat Index utilizes the temperature measured in the shade and therefore will likely be greater in the sun, where many activities take place. For temperatures taken in the full sunlight, Heat Indices can increase as much as 15°F. Humidity plays a major effect on cooling the body. If the humidity is high, sweat on the surface of the skin does not evaporate as quickly, slowing the cooling of the body. If the humidity is low, sweat evaporates too fast, leading to dehydration. [See link for Heat Index chart]
"Wet Bulb Globe Temperature (#WBGT) is similar to the Heat Index in that it is an indicator of the stress on the body from the heat. While it is not as well-known as the Heat Index, it’s not a new term. WBGT was developed in the 1950s after heat related illnesses affected the US armed services during the 1940s. After its implementation, there was a reduction in heat related illnesses during basic training. One fundamental difference between the Heat Index and WBGT is that the latter is calculated with the temperature measured in the sun. While Heat Index only takes temperature and Relative Humidity into account, WBGT takes several variables into account.
These variables include:
- Temperature
- Humidity
- Wind Speed
- Sun Angle
- Cloud Cover
- Physical Activity"

#HeatIndex versus #WetBulb temperatures
The world needs a new way to talk about heat
by Michael J. Coren
July 25, 2023
"[The heat index] warning system is not perfect. First, it assumes you’re resting in the shade, not working in the sun. If you’re exerting yourself outdoors, the effective heat index could be 15 degrees higher. Secondly, the heat index was built on the idea of a young and healthy adult — a bad assumption for the elderly, very young and sick."

Scientists Identify The Maximum Heat Limit The Human Body Can Take
Scientists have identified the maximum mix of heat and humidity a human body can survive. Even a healthy young person will die after enduring six hours of 35-degree Celsius (95 Fahrenheit) warmth when coupled with 100 percent humidity, but new research shows that threshold could be significantly lower.
