Every ride aboard a Hurricane Hunter is a bumpy one, but some flights are notorious for the level of turbulence they see. In a <a href="https://doi.org/10.1175/BAMS-D-24-0065.1">recent analysis</a>, researchers used flight data since 2004 (as well as a couple of infamous historic flights) to determine a “bumpiness index” that people aboard each flight would experience, based on the plane’s accelerations and changes in acceleration (i.e., jerk). </p> <p>The analysis confirmed that a 1989 flight into Hurricane Hugo was the bumpiest of all-time, followed by a <a href="https://www.youtube.com/watch?v=5a16ggD8Jt4">2022 flight into Hurricane Ian</a>, which was notable for its side-to-side (rather than up-and-down) motions. Overall, they found that the most turbulent flights occurred in strong storms that would weaken in the next 12 hours, and that the bumpiest spot in a hurricane was on the inner edge of the eyewall. That especially turbulent region, they found, is associated with a large gradient in radar reflectivity, which could help future Hurricane Hunter pilots avoid such dangers.

In doing so, it captured the detailed images seen here, where three coronal mass ejections — giant releases of plasma, twisted by magnetic fields — collide in the Sun’s corona. Events like these shape the solar wind and the space weather that reaches us here on Earth. The biggest events can cause beautiful auroras, but they also run the risk of breaking satellites, power grids, and other infrastructure.

Teratons of such materials enter the atmosphere from the ocean each year. To better understand how contaminants can cross from the ocean to the atmosphere, <a href="https://doi.org/10.1103/PhysRevLett.134.214001">researchers studied</a> what happens when a oil-coated water bubble pops.</p> <p>The team looked at bubbles about 2 millimeters across, coated in <a href="/2023/05/oil-covered-bubbles-popping/">varying amounts of oil</a>, and observed their demise via high-speed video. When the bubble pops, capillary waves ripple down into its crater-like cavity and meet at the bottom. That collision creates a rebounding Worthington jet, like the one above, which can eject droplets from its tip. </p> <p>The team found that the oil layer’s thickness affected the capillary waves and changed the width of the resulting jet. They were able to build a mathematical model that predicts how wide a jet will be, though a prediction of the jet’s velocity is still a work-in-progress.

In this satellite image of the lake in March 2025, about a third of the lake remains ice-covered, while <a href="/tagged/sedimentation/">sediment</a> — resuspended by wind and currents — and <a href="/tagged/phytoplankton/">phytoplankton</a> swirl in the ice-free zone. In recent decades, scientists discovered that diatoms, one of the phytoplankton groups found in the lake, can live within and just below Erie’s ice, thanks to a symbiotic relationship with an ice-loving bacteria. This symbiosis allows the diatoms to attach to the underside of the ice and gather the light needed for photosynthesis. Even in the depths of winter, an ice-covered lake can teem with life.
