💁🏻♀️ TIL: ⚡🔈 Thunder is the explosive #sound of air rapidly expanding and collapsing around #lightning’s 30,000°C heat.
Meteorologist Jonathan Belles explains how terrain like #valleys can funnel the sound, while temperature inversions create a megaphone effect that amplifies it. Positive lightning strikes carry up to ten times more #energy and produce much louder #thunder than typical strikes.

First Atmosphere Detected on a Terrestrial World
https://atlas.whatip.xyz/post.php?slug=first-atmosphere-detected-on-a-terrestrial-world
<p>A team of astronomers have discovered helium escaping from a rocky planet
#terrestrial #astronomers #atmosphere #detected -
Astronomers have detected an #atmosphere around a rocky #planet orbiting in the #habitable zone of a nearby #star.
Such planets around red dwarf stars have long been considered the best places in the galaxy to look for signs of alien #life. But so far, the #planets looked like bare rocks.
It wasn’t clear if planets like this could even have atmospheres. Now we know that they can.
The planet, LHS 1140b, is about 5.6 times as massive as Earth and 1.73 times Earth’s size. Those dimensions are consistent with an Earthlike composition shrouded in a gaseous atmosphere, or perhaps a global ocean of water.
It also orbits far enough from its star that its surface temperature could support liquid water.
Astronomers observed the molecular fingerprint of excess #helium gas absorbing light from the star. That excess is a sign of helium streaming away from the planet’s atmosphere, implying that it indeed has an atmosphere.

ROBIN MEETS THE #FEDIVERSE
ROBIN: So #Mastodon is not the fediverse?
GPT: No. Mastodon is one part of it.
ROBIN: One part of what?
GPT: A large network of independently run communities that can communicate with one another.
ROBIN: So my Mastodon #server is one #community
#GPT: Exactly. Your #account lives there. It has its own administrators, rules, #moderation #culture and general #atmosphere.
ROBIN: General atmosphere?
GPT: Some servers feel like #libraries. Some feel like university #common rooms. Some feel like #pubs where everyone has read one article and now considers themselves an #expert.
ROBIN: That sounds more like humanity.
GPT: It is disturbingly similar.
ROBIN: Who owns the fediverse?
GPT: No one.
ROBIN: Who is in charge?
GPT: Also, no one.
ROBIN: That sounds either very advanced or completely mad.
GPT: Both can be true.
ROBIN: So each server looks after its own patch?
GPT: Yes. It can make #rules, moderate its space and decide which other servers it will interact with.ROBIN: But I can still follow people elsewhere?
GPT: Usually, yes. You can #follow, reply to and #boost people across server boundaries.
ROBIN: So it is more like email than #facebook ?
GPT: Precisely. #Gmail does not own #email. Mastodon does not own the fediverse.
ROBIN: Then why does my server matter?
GPT: Because it is your home base. It holds your account, your posts and your followers. It also gives you a local community and sets things such as the character limit.
ROBIN: Ah yes. Mastodon.social gives me 500 characters. Mastodon.au gives me 2,000. Aus.social gives me 3,000.
GPT: Different #villages. Different-sized noticeboards.
ROBIN: Is a larger server more widely seen?
GPT: Sometimes #locally, because more people may browse its community feed. But real reach still comes from #followers, replies, boosts and hashtags.
ROBIN: So moving to a bigger server does not #automatically make me famous?
GPT: #Tragically, no.
ROBIN: Can I have accounts on several servers?
GPT: #Certainly. One can be home, another a backup, and another an #emergency cottage when the village #electricity #fails.
ROBIN: Which it did today.
GPT: Yes. Mastodon.au disappeared behind a #Cloudflare #Error 522 for hours.
ROBIN: So the fediverse is not one vast #machine going down?
GPT: No. One village can lose power while the rest of the #country carries on.
ROBIN: That is reassuring.
GPT: And inconvenient.
ROBIN: Mostly inconvenient.
GPT: But you now know more about the #fediverse than you did this morning.
ROBIN: I learned that it is decentralised, #untidy, resilient, occasionally broken, and full of different #neighbourhoods, customs, friendships, arguments and difficult people.
GPT: Much like #human life.
ROBIN: And the #occasional village lunatic shouting across the fence.
GPT: Every #healthy community #needs one.
ROBIN: At last, a clear role for me.

A Red Sun Rises
My trip to the mailbox this morning began peacefully enough, a quiet stroll through a slowly brightening day. Then I looked up. The sun hung in a hazy sky, its light filtered by particulates from fires in Quebec, leaving a visible disk that looked like a second moon. The smoke changed the usual morning light from bright yellow to a darker, ruddier hue. Very dramatic.
Today’s forecast? Thunderstorms, which brought to mind the old adage about skies and sailors. “Red sky at night, sailor’s delight. Red sky in morning, sailor’s warning.” It turns out to be based on atmospheric science, and while the logic doesn’t hold up everywhere all the time (and yes, smoke can interfere with its accuracy), it can be useful.
Red Sky at Night: Is the Sailor’s Saying Really True?
The folklore lines up with two pieces of plain physics: how air moves and how light scatters. Low pressure pulls air together and lifts it, which builds clouds and brings rain. High pressure does the opposite. Air sinks and spreads out, which keeps the sky clear and traps dust and fine particles near the ground. Sailors learned the shorthand long before anyone measured a millibar: low pressure for foul weather, high pressure for fair.
Happily, forewarned is forearmed (to use another old adage). Now I wait, and watch for the coming storm.

The smoke changed the usual morning light from bright yellow to a darker, ruddier hue. Very dramatic.
Today’s forecast? Thunderstorms, which brought to mind the old adage about skies and sailors. “Red sky at night, sailor’s delight. Red sky in morning, sailor’s warning.” It turns out to be based on atmospheric science, and while the logic doesn’t hold up everywhere all the time (and yes, smoke can interfere with its accuracy), it can be useful.
Red Sky at Night: Is the Sailor’s Saying Really True?
The folklore lines up with two pieces of plain physics: how air moves and how light scatters. Low pressure pulls air together and lifts it, which builds clouds and brings rain. High pressure does the opposite. Air sinks and spreads out, which keeps the sky clear and traps dust and fine particles near the ground. Sailors learned the shorthand long before anyone measured a millibar: low pressure for foul weather, high pressure for fair.
Happily, forewarned is forearmed (to use another old adage). Now I wait, and watch for the coming storm.
A red sun rises.

[Flash floods? not TOO hard to conceptualise.
Flash drought? harder to 'get my head around', but H/T / presenter does an excellent job!]
"Not all droughts are the same. In some cases, drought rapidly intensifies at subseasonal to seasonal scales with significant impacts to agriculture and water resources along with the increased propensity for heatwaves and wildfires. Like all droughts, flash drought begins with a precipitation deficit. However, both evaporative demand and soil moisture are critical flash drought variables, and identifying and monitoring the desiccation of the terrestrial surface is key for determining flash drought development and associated impacts. While recent advances in knowledge and monitoring of flash drought have occurred, fundamental questions remain in the state of the science. What are the overall mechanistic relationships between atmospheric demand, evaporative stress, terrestrial desiccation, and precipitation that drive the progression of flash drought? Do regional characteristics of the environment impact the evolution of flash drought? What are the scales of predictability for flash drought? Finally, how will flash drought frequency and intensity evolve in a changing climate system"

"Flash drought intensifies rapidly due to changes in precipitation, temperature, wind, and radiation. These changes in the weather increase evapotranspiration and lower soil moisture. Flash droughts can cause extensive damage to agriculture, economies, and ecosystems if they are not predicted and discovered early..."
