#SimulatedUniverses
One of my best ever visualisation of the plasma maelstrom which might exist (but yet invisible to us - need much more powerful X-ray telescopes in the far future) in clusters of galaxies.

This was a zoomed adaptive mesh refinement simulation ran in 2010 with the ENZO code at Cineca, as part of a national key project.

(The simulation was so big it could not even reach the end, this is a redshift z=0.6 snapshot)

“Vorticity 6”

It’s time for another storm-chasing timelapse from photographer Mike Olbinski! “Vorticity 6” focuses on supercell thunderstorms and their tornadoes. There’s billowing turbulent convection, undulating asperitas, bulging mammatus, microbursts, and more. There’s nothing like timelapse to highlight the growth, rotation, and shear involved in these storms. (Video and image credit: M. Olbinski)

Help me, I just go, we can all go up
무사히 도착하길 빌어 야간비행
I shine on my own (own)
사람들은 그걸 별이라 부를 테니 그저 빛나면 돼
(Passion, young, fever)

이 끝에 우린 여기서 지금 모습으로 무엇이 돼야 한다면
나는 내가 되기를 바라, 너도 같기를, whoa
듣고 있나요 누군가? 가슴에 새길 이 노래
우리 여기서 지금 모습으로 그대로여도 괜찮아 tonight

매일 밤 시린 마음, 거친 싸움, 지친 날 (oh, whoa)
따스한 온기로 안아줘요 (안아줘요)
매일 밤 시린 바람, 거친 파도, 지친 날
Still fly, 더 안아줘요 (hey, oh)
Whoa-oh-oh-oh-oh-oh-oh-oh-oh
Whoa-oh-oh-oh-oh-oh-oh-oh-oh

Bumpy skies: How climate change increases air turbulence.

For many flyers, air turbulence can be an unnerving experience – and in a world warming under the effects of climate change, it is only set to worsen, according to a growing body of scientific evidence.

Studying Hydroelastic Turbulence

Can energy at the small-scales of a turbulent flow work its way up to larger scales? That’s a question at the heart of today’s study. Here, researchers are studying hydroelastic waves — created by stretching a thin elastic membrane over a water tank. The membrane gets vibrated up and down in just one location with an amplitude of about 1 millimeter. The resulting waves depend both on the movement of the water and the elasticity of the membrane, mimicking situations like ice-covered seas.

Rather than simply dying away, the local fluctuations introduced at the membrane spread, coalescing into larger-scale hydroelastic waves. How energy flows between these scales could have implications for weather forecasting, climate modeling, and other turbulent systems. (Image and research credit: M. Vernet and E. Falcon; via APS)

Veil Nebula

These glowing wisps are the visible remains of a star that went supernova about 7,000 years ago. Today the supernova remnant is known as the Veil Nebula and is visible only through telescopes. In the image, red marks hydrogen gas and blue marks oxygen. First carried by shock waves, these remains of a former star now serve as seed material for other stars and planetary systems to form.

Seeding Clouds With Wildfire

Raging wildfires send plumes of smoke up into the atmosphere; that smoke is made up of tiny particles that can serve as seeds — nucleation sites — where water vapor can freeze and form clouds. To understand wildfire’s effect on cloud growth, researchers sampled air from the troposphere (the atmosphere’s lowest layer) both in and around wildfire smoke.

The team found that smoke increased the number of nucleating particles up to 100 times higher than the background air, but the exact make-up of the smoke varied significantly by fire. Smoke particles were mostly organic, though inorganic ones appeared as well. The temperature of a fire, as well as what materials it was burning, made a big difference; the fire where they measured the highest particle concentrations included lots of unburned plant material, thought to be carried aloft by turbulence around the fire.

Turbulence forces Delta flight to land and sends 25 passengers to hospitals, airline says - This is an under-reported side effect of #ClimateChange and #GlobalWarming that many folks are unaware of. The #ClimateCrisis promises to make #AirTravel much more dangerous because of increased #turbulence. If we don’t do something substantial to turn this around soon, traveling by air just might become a lot more risky. #ClimateEmergency #airlines https://apnews.com/article/delta-flight-turbulence-injuries-f93bc14c4c6f27d0be137483938fddfe

From CNN.com: More than two dozen on Delta flight taken to hospitals after turbulence forces plane to make emergency landing

https://www.cnn.com/2025/07/31/travel/delta-minneapolis-emergency-landing-turbulence-hnk

Welcome to Minneapolis! It's ain't Amsterdam but it's our town.

Air travel sounds dreadful.

"The Associated Press reported that serious injuries from in-flight turbulence are rare, but scientists say they may be becoming more common as climate change alters the jet stream."

We have a new toy: a dji Dock 3 with Matrice 4D #multicopter!

With this and our PARASITE payload on top, we can automate our atmospheric profiling flights and do *even more* #turbulence measurements for #windEnergy, #mountainWeather and improving #weatherForecast parametrisations

These #turbulence events are getting more frequent and more violent. How long with it be until their atmosphere is too cooked to allow for safe air travel?

ABC News: 25 hospitalized after severe turbulence on Delta flight

There were 275 passengers and 13 crew members on board, the airline said.

"...Twenty-five people aboard a Delta Air Lines flight, headed from Salt Lake City to Amsterdam, were hospitalized after the flight encountered severe turbulence Wednesday, the airline said...."

#CopterPortrait Meet Flik¹, the #multicopter we developed our first #PARASITE payload for. It's a commercial dji Mavic 3E drone typically used for photography. Here, Flik is measuring for the #TeamX campaign in #Austria, which will eventually improve #mountainWeather forecasts.

Our PARASITE system (running #NixOS) has several ventilated meteorological sensors on board for temperature and relative humidity.

From all the data we get from copter and sensors we derive a fast 3D wind measurement. So yes: We can now measure #turbulence with a copter, without the need for an actual anemometer: The copter is our anemometer!

Comparisons in #Falkenberg with a @DeutscherWetterdienst tower shows that the data quality is comparable to ultrasonic anemometers - the current gold standard of operational turbulence measurements.

Bow Shock Instability

There are few flows more violent than planetary re-entry. Crossing a shock wave is always violent; it forces a sudden jump in density, temperature, and pressure. But at re-entry speeds this shock wave is so strong the density can jump by a factor of 13 or more, and the temperature increase is high enough that it literally rips air molecules apart into plasma.

Here, researchers show a numerical simulation of flow around a space capsule moving at Mach 28. The transition through the capsule’s bow shock is so violent that within a few milliseconds, all of the flow behind the shock wave is turbulent. Because turbulence is so good at mixing, this carries hot plasma closer to the capsule’s surface, causing the high temperatures visible in reds and yellows in the image. Also shown — in shades of gray — is the vorticity magnitude of flow around the capsule. (Image credit: A. Álvarez and A. Lozano-Duran)
