In the post about climate change yesterday, I mentioned wanting to do a post about one particular wildfire in Oregon that had grown so intense that it was creating it's own weather system.
Well, here is that blog entry, with the link to the article from which I first hear about this story, from approximately one year ago.
According to Matthew Rozsa in the article below, this wildfire, which is big enough to have been given a name: the Bootleg Wildfire:
is creating pyrocumulus clouds. These are dense clouds that form in a cumuliform manner (meaning they develop vertically) and are associated with volcanic eruptions or fires. When the extreme heat from a wildfire's flames cause the air to rise rapidly, the moisture on smoke particles produced by the fire condense and cool. This process ultimately causes the clouds to produce high winds and even lightning, in a sense becoming their own thunderstorms. USA Today described the tops of the clouds as looking like anvils. This is not only because of their shape but their color: they tend to be dark and gray because of the ash and other fire-related particles contained within them.
NASA is warning us that this is the kind of firestorm that we should expect in the future. In other words, this may just be the first of a coming trend.
Wonderful, eh?
