Wildfires in Oregon cause miles of “clouds of fire” as the flame grows | Oregon

Smoke and heat from a huge wildfire in the southeast Oregon It creates a huge “cloud of fire” on the flames. Dangerous pillars of smoke and ash can reach up to 6 miles (10 km) in the sky and can be seen from more than 100 miles (160 km) away.

Authorities have placed these clouds at the top of the list of extreme fire behaviors found in Bootleg fires. The biggest wildfire Burning in the United States. Inferno grew to about 75 square miles (194 square kilometers), larger than New York City on Friday, raging parts of the western United States that have withstood the historic drought.

This week’s meteorologists have also discovered a larger, more extreme form of fire cloud. This allows you to create your own weather, such as a “tornado of fire.”

Extreme fire behavior, including the formation of more fire clouds, was expected to persist on Friday and worsen on weekends.Currently At least 70 With a wildfire burning in the western United States Dozens more In Canada.

Firefighters were scrambling on Friday to control the raging Bootleg fire, which spreads miles a day in windy conditions. Authorities ordered a new evacuation, fearing that Inferno, which had already destroyed 21 homes, could merge with another flame that also exploded.

Flammagenitus clouds (literally translated as “fire clouds”) look like giant, dirty-colored thunderclouds on huge pillars of smoke from wildfires. Often, the top of the smoke column is flattened into an anvil shape.

Clouds form between 3 pm and 5 pm daily as the sun penetrates a layer of smoke to warm the ground below and create an updraft of hot air, according to Oregon fire authorities. The crew sees the largest and most dangerous clouds on a section of the wilderness, mostly composed of dead trees. They burn instantly and with a lot of heat.

Officials said on Friday that the Bootleg fire had risen nearly six miles into the atmosphere for four consecutive days, creating multiple fire clouds that were “easily visible from 100 to 120 miles away.” Cloud-building conditions were expected to worsen over the weekend.

Once a flammagenitus cloud is formed over the fire, meteorologists begin to closely monitor its brother, the flammagenitus cloud. Nasa calls the latter a “fire-breathing cloud dragon.” Because it is so hot and big that it creates its own weather.

In the worst-case scenario, a ground fire brigade could see one of the monster clouds spawn a “tornado of fire”, creating its own dry thunderstorm and creating dangerous hot air below. Clouds can also send particulate matter up to 10 miles above the surface of the Earth from the smoke column.

So far, most of the Bootleg fire clouds have been less strong, but on Wednesday the National Weather Service discovered the Pyrocumronimbus cloud, which is formed by so-called “horrible” satellite images.

“Send positive thoughts and wishes to the firefighters … it’s a tough time for them,” the Meteorological Department said in a tweet.

Meanwhile, a fire near Paradise, a town in northern California, was largely destroyed by a wildfire in 2018, killing 85 people and having just begun to return to normal after overcoming the worst flames in US history. I was worried about the person.

In Washington, a wildfire threatened more than 1,500 homes near Wenachi, expanding to 14 square miles (36 square kilometers), with little control of the crew, according to the Washington State Department of Natural Resources.

Extremely dry conditions and climate-related heat waves have hit the western United States, making it difficult to fight wildfires. Climate change has made the region much warmer and drier over the last three decades, making the weather more extreme and wildfires more frequent and destructive.
