Forget #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"

Perhaps the best approach would be to get a device that can measure the local wet bulb globe temperature. This seems to be an option:

https://kestrelmeters.com/kestrel-5400-heat-stress-tracker

Does anyone have recommendations for wet bulb thermometers?

#WetBulb #WBGT

I now have two apps that tell me the wet bulb globe temperature (#WBGT), as well as a forecast:

- Heat Safety: https://play.google.com/store/apps/details?id=com.qvyshift.heat
- AIHA Heat Stress App: https://play.google.com/store/apps/details?id=com.aiha.prod

https://www.aiha.org/press/aiha-launches-new-heat-stress-mobile-app

Sadly, these apps don't agree on the current WBGT. The man with one clock knows what time it is, the man with two clocks isn't quite sure!

Both depend on the National Weather Service, so who knows how long they will remain trustworthy, given Trump's war on weather forecasting.

#WetBulb

Are there any #publichealth / #heatstress / #heat / #climate professionals on here who’d be willing to briefly consult on a #heatsafety project I’m designing?

I’m trying to make #WBGT more intuitive and actionable for the general public (but especially #construction workers and #running/ #athletes), and I want to modify how the temperature is presented, responsibly.

Thank you!

(Draft design attached, but seeking expert feedback on things not pictured here.)

"Extreme" Wet Bulb Globe Temperature forecast from the NWS in interesting. I wonder if it's calibrated or not. 96F WBGT here, which is maybe (?!) somewhere near the limits of humans without supplemental air conditioning... (technical details on this are not clear to me). #CAwx #AZwx #TXwx #NVwx #heatwave #WBGT

Wet Bulb Globe Temperature (WBGT) forecasts for tomorrow Friday 6/30/23 👀 #WBGT #heatwave #humidity https://digital.mdl.nws.noaa.gov/

"Extreme" Wet Bulb Globe Temperature (WBGT) for #Texas right about now. Dramatic heat illness risk if people don't have access to A/C or are working outdoors... or your car breaks down. Or you are homeless. Or if you decide to take a walk around the block.95F WBGT is the limit of human tolerance. #wbgt #heatwave #heat https://digital.mdl.nws.noaa.gov/

so TIL that the #weather service has a page for US #WetBulbTemperature

This measurement will prolly become really important, soon.

#WetBulb Globe Temp (#WBGT) measures #heat stress in direct sunlight & takes into account: temp, #humidity, wind speed, sun angle & cloud cover.
so it's way better IMO than heat index, which is taken in shade.

#Climate #ClimateChange

human survivability limit is estimated to be wetbulb 95F. It's wetbulb 91 in south texas right now

@peterreiners Thanks! Been hunting for #wetbulb maps since #MinistryForTheFuture came out in 2020. #WBGT #wawx

Wir sind bereits kurz vor der Unbewohnbarkeit größerer Gebiete.
Bei der Unbewohnbarkeit vor Hitze geht es weniger um "normal" gemessene Temperatur, sondern um die Chance auf Verdunstungskälte.
* #Kühlgrenztemperatur (gemessen etwa mit feucht gehaltenem Thermometer; paar Stunden 35°C sind für Menschen tödlich)
und
* #WBGT (wet-bulb globe temperature, siehe verlinkter Artikel, »Ab einer WBGT von 31 Grad wird es kritisch, bei mehr als 32 Grad definitiv gefährlich.«)
