Good job Holt you and Zeke need to keep educating the masses on why their state, prior to climate change impacts, was at high potential for devastating wildfires as well as now with climate change. This year was a bit of an off year but soon it will return. Instability can be simply put as think of a chimney and how well your fire burns in the fire place or wood stove when the damper (stability) is shutl and then think of how well a a fire burns when the damper (instability) is open. However don’t think just because the atmosphere is stable or not doesn’t mean that a going fire won’t burn nor a new fire won’t get big. And Californians can’t control the stability of the atmosphere. It happens as part of yearly climate changes. But what you can control is firewising your property and knowing where the safety zones are in your community if you can’t evacuate.
Because afterall, the Santa Annas occur because of the pressure difference between a big and long lasting high pressure (stable atmosphere) that sits out over the great basin and a low pressure (instable atmosphere) off the coast of CA and that because of that pressure difference where wind is always sucked into a low pressure and a high pressure is always giving its wind to the low pressure and because that high has sat over the Great Basin for a while and a strong low is sitting of the coast that what develops is a Foehn Wind (warming and drying wind) or the Santa annas or others depending on where you are at. The winds that develop are warm, dry, and flowing downhill as compared to the mountain range and carry fire downhill at night mostly and also sometimes during the day. We are in that season now.
I must say you have an excellent way of communicating these concepts.
Awesome information Holt!! Keep up the excellent reports and updates. 🏆👍🏻🏄
