How far from a forest fire do you have to be for a daily temperature record to count?
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?
You're viewing a single thread.
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.
