There have been some impressive (and scary) temperature records set in the past couple weeks. That said, there are parts of Canada that are currently on fire that likely have a daily temperature in the hundreds of degrees. Clearly that doesn’t count for any sort of temperature record. What I’m wondering is: where’s the dividing line? How far away from a big fire do you have to be to record a valid daily temperature?
Well, assuming fire temperature to be 800C and temperature drop off close to 1/r² - you need to be approximately 28 meters away from a point source to feel 1 degree Celsius increase in temperature. Forest fire is not a point source, it’s a wall of fire, but give it or take - 100 m away it you shouldn’t feel any heat coming from the first fire.
Other people are saying 2, is that close to 100m?
it’s about 2 of 100m / 2
It’s about 2 of 100m / m.
