No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Like I know embers and sparks travel, but I never imagined this absolute flurry of embers

That is how fire travels further faster and can hop over fire breaks and highways.

The uplift caused by the fire can send heavier and longer burning embers higher, which then the wind can carry a fair distance away.

I'm not an expert, just living in a country that has lots of bushfires, Australia.

Fire spreads in all manner of ways. Embers can be picked up by the wind and transported kilometres away from the firefront. Birds can pick up embers and drop them away from the fire. Burning materials can get stuck underneath a vehicle, or fire can race against the wind up a hill.

Something to keep in mind is that fire is a chemical reaction that needs fuel, oxygen and heat.

Birds can pick up embers and drop them away from the fire.

Is this common?

They also deliberately use fire to smoke out prey. The phenomenon calls them "Australian Firehawks".

[–] erusuoyera@sh.itjust.works 5 points 2 days ago

Some birds like use smoke as a way to fumigate their feathers, so will pick up embers and take them somewhere, as this is safer than standing next to a fire.

[–] vk6flab@lemmy.radio 5 points 2 days ago

As I understand it, in Australia it's not uncommon. I don't know if it happens elsewhere.

  1. Make controlled burns the engineers said.
  2. Create fire barriers.
  3. Stop putting lots of plant life where ground fires might run thru. -All of this was said by Indians, engineers, and people from other countries where they have similar annual burn cycles. Yet here we are, "is it normal to see fire embers wafting thru the street like a lost vacationer?" So what do politicians do? Cut fire fighter funds for the democrats, and trump literally said "rake the forest to remove stuff that burns." Like... The whole forest... The forest that is bigger than San Francisco... Are they gonna use homeless??? Cuz he's deporting all the manual labor immigrants. Republicans and Democrats are not going to help you. They are the problem. Both need to be removed from office with extreme prejudice.

They do controlled burns, but the ability to do that safely has been hampered by years of drought conditions. At least Democrats admit climate change exists I guess?

That and fire is extremely hot when it's big. If you've never been near a house fire or a forest fire, you might underestimate just how hot shit can get even several feet away from the actual fire or embers. Hot enough to ignite things even without actual contact. You may see them dumping water nowhere near any flames, and it's to hopefully slow or stop it from spreading.

UCLA Climate scientist, Daniel Swain talks about this exact topic during his recent interview with Adam Conniver on his podcast, Factually.

Go to timestamp 17:45 and you'll hear Swain talk specifically about how this was a unique firestorm.

Earlier in the interview (around the 12:00 minute mark) Swain points out that it has to do with the increasingly longer periods in between wet and dry periods that are occurring that contributed so heavily to the conditions for a fire of this magnitude becoming more likely to occur, especially when particularly strong Santa Ana Winds occurring this year.

[–] someguy3@lemmy.world 2 points 2 days ago

That's the guy in the first video I linked.

Embers are generally the spread method for fires but the winds in CA right now are extremely strong.

One curious thing to note though is that the heat of fires tends to create convection currents that locally increase wind - in this case that effect is just supplementing strong standing winds.

Its only southern thank god. Most of us are still ok.

Ashes tend to go up so that is partially what you are seeing.
