Nicole Sharp<p><strong>Seeding Clouds With Wildfire</strong></p><p>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, <a href="https://doi.org/10.1029/2020JD033752" rel="nofollow noopener" target="_blank">researchers sampled</a> air from the troposphere (the atmosphere’s lowest layer) both in and around wildfire smoke. </p><p>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.

Nicole Sharp<p><strong>Bow Shock Instability</strong></p><p>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. </p><p>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.

Nicole Sharp<p><strong>Stunning Interstellar Turbulence</strong></p><p>The space between stars, known as the interstellar medium, may be sparse, but it is far from empty. Gas, dust, and plasma in this region forms compressible magnetized turbulence, with some pockets moving supersonically and others moving slower than sound. The flows here influence how stars form, how cosmic rays spread, and where metals and other planetary building blocks wind up. To better understand the physics of this region, <a href="https://doi.org/10.1038/s41550-025-02551-5" rel="nofollow noopener" target="_blank">researchers built</a> a numerical simulation with over 1,000 billion grid points, creating an unprecedentedly detailed picture of this turbulence.</p><p>The images above are two-dimensional slices from the full 3D simulation. The upper image shows the current density while the lower one shows mass density. On the right side of the images, magnetic field lines are superimposed in white. The results are gorgeous.

Nicole Sharp<p><strong>Proving Superdiffusion</strong></p><p>Turbulence is very good at spreading things out. Drop dye into a turbulent flow and it will quickly disperse. Add in particles — like rubber ducks — and they can spread apart, often at speeds quicker than one would expect, based on the background flow. This is (roughly speaking) a phenomenon known as “<a href="https://en.wikipedia.org/wiki/Anomalous_diffusion" rel="nofollow noopener" target="_blank">superdiffusion</a>,” where turbulence makes particles that start out as neighbors part ways.</p><p>Physicists conjectured that turbulence — including simplified and idealized versions of it that are simpler to deal with — had this superdiffusion property, but no one was able to show that in a mathematically rigorous way. But now a group of mathematicians has done so, using a technique known as homogenization. There’s a lot more on the story over at <a href="https://www.quantamagazine.org/new-superdiffusion-proof-probes-the-mysterious-math-of-turbulence-20250516/?__readwiseLocation=" rel="nofollow noopener" target="_blank">Quanta</a>, or you can check out the original papers on arXiv.
