Because the scientists were enamored with the music from that decade?
Why are B.C. firefighters still using wildfire data from the 1990s?
Forecasters say prediction models are underperforming during province's extreme fires
A lot of the Canadian Fire Danger measurements are old....and many are based upon presecribed burn observations which are not done under extreme conditions.
So when you do deal with extreme drought....that's not modelled as you're into upper 90th percentile conditions and thats not when most fires start. However when you look at catastropic large scale fires they are often related to drought....
So you're balancing between how often your fires start and forecasted growth vs. extreme situations. Then you start dealing with local modifiers like growing climate, insect damage, windthrow, drought....hence why a Fire Behavior Analyst is such a specialized position and takes significant specialized training.
There is also alot of chatter around extreme weather events and impacts on fire growth. I'm still not clear how much of this is better documentation of fire events vs. historic fires. Something like Jasper in 2024 has already been anaylzed vastly more - due to modern documentation - than much larger and catastrophic fires like
The Miramichi Fire of 1825 National Historic Event
For quick summery the link refers to a 1825 fire in what is now New Brunswick that burnt about 20% of the province and killed an estimated 500 people out of a population of 8500.
Location of the fire also means alot...if you're in a remote area modelling errors are okay as they're "good enough" and the FBAN can adjust for the next assesment. But when you are dealing with a community adjacent to the fire the expectation today is perfection and that's a much tougher bar to reach.
To put this in a context many of you may understand....it doesn't matter the battle plan you have...the enemy has a vote too. The difference here is instead of an armed opponent you're dealing with nature/weather which can be predicted...but gets a say as well.
