Hot days continue。That's also "dangerous heat."。by the way、How many times have you been doing "dangerous heat"? I asked AI。
--According to AI, the temperature alone is not enough to know about dangerous heat.、Humidity added、It is judged by the overall "heat index" (WBGT).。"Dangerous heat" refers to WBGT above 31°C.。Incidentally, if WBGT is 28°C or higher, "Serious warning"。25"Caution" if it is above ℃。25Exercise even if it is below the level、It is said that you need to be careful of heat stroke in heavy labor.。
First of all, what is "WBGT"? From that point。It is a lined up of the initials for Wet Bulb Globe Temperature.。Literal translation? Then the wet bulb、Black ball、Dry bulb temperature”。What is called a dry bulb?、Common thermometers。Wet bulbs are called "wet bulbs" wrapped around them with a damp cloth.、Measures the temperature reduced by the heat of vaporization when moisture evaporates from the fabric。Calculate the humidity based on that difference。The black ball is、A thermometer is placed inside a copper sphere painted with no light reflecting paint.、Measures radiant heat from the ground。
in short、If we summarise those three values、It is said that you can calculate something called the "heat index."。I see、This is an explanation that may be true or not.、It didn't really understand。The same goes for the effectiveness of the "heat index" (though I will avoid describing it in detail).、WBGT 31℃、The relationship with normal temperatures is now closed by a single (probabilistic) word called "heat index."。I can't trust that。
Once upon a time、There was a term called "discomfort index" that was a weather term.。temperature、Even if the humidity is high、If there's a moderate wind there、The feeling of heat is slightly "healing"、I remember that it was an "exponent" that took into consideration the senses、I haven't heard it anymore lately。I'm not saying it sarcastically、I feel that this is because people's "discomfort" has become too complicated。
The "index" is、It is a very useful and (economical?) valuable word for researchers (and even more for the government)、"We'll define this, this and that as the ○○ index"、I'll be accepted for now。If you don't do that、Of course, the argument cannot be made further.。After that、In the process of investigating the consistency between the defined data and actual data、If you get the feeling of "I see" then it will become more established。But、Please think about it carefully。"We'll arrange this, this and that to define it as the ○○ index."、Anyone can customize it without permission。"That's what the definitions expressed in AI are."、I think about it、Looks just right。
