    Why should we know about this super rare event exactly? They can’t even happen in the region of the world I live in. I don’t think anyone was ever hurt by one? The events are usually short and rather mild?

    https://en.wikipedia.org/wiki/Heat_burst

    Most listed here don’t get above 40C? We have regular days in summer where it’s around 40 all day. Sure it’s hot, but not unheard of hot and certainly not something to worry about happening. It might be weird if the temperature suddenly jumps from 24C to 34C, but that’s all it is, just kinda weird.

    I saw that YouTube video when it released and it was really interesting. But it’s just a cool niche weather phenomenon, not something people should know.

      Nothing, people did nothing, these things aren’t life threatening. So in order to survive them you just need to wait till it’s over.

      There is this one case discussed in the YouTube video from almost 70 years ago where it is claimed the temperature got up to 60 degrees C. But all of the events in past 30 years with proper data haven’t gotten above 40C, so I would very much doubt the 60C figure. These events are also brief, lasting at most a few hours. They are also rare and can only happen in specific places.

      The old footage they have in clip is so unique I thought it’d be best for the episode to do the talking.

      For those want a tl:dr/dw:

      *Some people took shelter in underground tornado shelters. *Others held cold rags soaked in water from the tap near their mouths to cool the air around the mouth, making it more breathable. *If I recall correctly there was a few that went to nearby rivers, creeks, and ponds. Staying in them the whole time.(I’m sure there is more but that is all I recall.)

        Okay, thank you!

        I was kinda curious if there were new techniques being demonstrated here, but I guess that’s pretty traditional stuff. Still, some may not know these things, so good share.

    We deal with tornados here and there in NJ, but nothing like tornado alley out west. I’ll add heat bursts to the list of reasons why living out that way is scary as hell.

    I’ve been in 52 C heat (125 F) and it’s no joke, but you can still walk around, even in the sun, without exerting yourself too much.

    I’ve also been in a room at 70 C (almost 160 F) for a few minutes and that was terrifying. The air is as if burning your insides, it’s absolutely unbearable. There is a world of difference between these two. I image 60 C for four hours would start killing people, particularly the elderly.

      35c (95 f) is the wet bulb temperature where the human body stops being able to cool itself. Humidity plays a role, but generally above this temperature you’re going to get heat stroke if you can’t find external ways to cool off. So yeah 52c would definitely be enough to be killing people without a/c, fans, cold water, etc.

        Yeah, no. 95F is a normal summer temperature here. I’ve done farm work for hours in triple digit temps in direct sunlight without getting heat stroke.

        It’s something you have to be acclimated to, though, and you have to know to frequently drink water.

          A) Drinking water is external cooling, just inefficient.

          B) No, your anecdote doesn’t change reality. though the 35c is a good reference point humidity does matter. If you cannot sweat you cannot cool down. Period. End of story.

          At 35c you MUST be able to sweat or cool down in some other way, or you will die. just the close you are to 100% relative humidity at that temp, the less you will be able to sweat. So you will have one less method of cooling down.

          Many people have no problem living in 35-40c temps with low humidity. Maybe up to 45c with 0% relative humidity.

          There are not humans that have survived 35c at 100% humidity for more than 2 hours. They don’t exist on this planet. They physically can’t.

        Humidity plays a big role. You can still cool down at 52 C if the air isn’t very humid (that is, when the wet bulb temperature is low enough). Wet bulb temperature is a particularly useful metric because it incorporates evaporative cooling in it. Sadly most thermometers can’t measure it.

    Trying to avoid YouTube (I hate that my phone chaged the case from lowercase on its own) is hard.

    The watch here option is still a YouTube stream, it just doesn’t open it in the YouTube app or open YouTube in the browser.
