"Wildfires, dramatic and destructive forces of nature, are complex events driven by a multitude of interacting factors. While fuel, ignition, and weather conditions are widely recognized, the role of convection, a fundamental heat transfer mechanism, often goes unappreciated despite its crucial contribution to the fire’s behavior and spread. Understanding how convection operates within a wildfire is essential for improving fire prediction, management, and mitigation strategies. This article delves into the intricacies of convection in wildfires, exploring its mechanisms, its impact on fire dynamics, and its implications for both safety and scientific research."

Of course they do. But at its base we have the fire triangle. Fuel, Oxygen, Ignition source.

Grass is a one-hour fuel source. That is if the wind blows for an hour the grass is ready to burn, provided it is not green.

California is spending $2.6 billion per year on healthcare for “illegal aliens”.

Thats a great link -just gave NewScum And Bass a touchup

There should be a windfarm at the Pacific Palisades, not densely built wooden luxury houses.

That is only for wet grass. Stupid.

"In the past decade, the United States has seen no shortage of natural disasters. From hurricanes that tear across the coast, destroying homes and flooding properties, to wildfires that consume thousands of acres of land, nature is often vicious and indifferent to human life. But it is also very peculiar. Most consider wildfires transient in their destruction, a singular event that burns forests and homes before firefighters quell the flames. But under the right conditions, an intense wildfire can produce its own weather with the potential to cause thunderstorms and—in some cases—“firenadoes,” and the science behind this phenomenon is fascinating."

What? Fires creating their own weather? Winds are weather.

"Wildfires can generate tornado-like fire whirls and other "unpredictable and erratic" weather. An atmospheric scientist explains how."

Wildfires generate fire-whirls? Oh dear.

"The fire sucked air towards it, generating wind speeds of up to 117km/h (73mph) and rocking cars in a nearby municipality. Still the flames charged on, now devouring 4,460 hectares (17sq miles) of forest an hour."

Again fire generating winds.

Your ref says 'Like in Portugal, the fires in Maule went through a sudden huge acceleration, says Castellnou. "By 25 January, the fire had been burning for 10 days, but that night it suddenly grew four times larger,'
--
It was uncontrolled wildfire for 10 days before the plume. On the first ignition,'Firefighters were on the scene within minutes, but by that point the wind speed around the fire had accelerated and the smoke plume had expanded to nearly a kilometre (0.6 miles) wide.' The PCB was 10 days later with 27 sq km burnt, generating heat.
