Deformation and failure mechanism of flat-nosed TC4 titanium alloy projectile penetrating steel target at different velocities

Materials & Design
The dynamic behavior of flat-nosed Ti-6Al-4V (TC4) alloy projectiles penetrating Q235 steel targets under three velocities (800 m/s, 983 m/s, and 1167 m/s) was studied experimentally and numerically, emphasizing the evolution of adiabatic shear bands of ...

Internal Tide Displacements Enhance Surface‐Interior Heat Exchange in the Indonesian Seas

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Sea surface temperature (SST) in the Indonesian Seas drives atmospheric deep convection, influencing regional and global climate. Yet, the processes controlling SST in this region remain poorly understood. Using a high‐resolution regional model that explicitly resolves internal tides, we show that tidal displacements lift cold thermocline ...

Analysis of Smoke Transport Over the Northeast US Caused by Wildfires in Canada During June 2023—Leveraging the HRRR‐Smoke Model Predictions and Remote Sensing Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The intensification of wildland fires across portions of Canada in early June 2023 led to significant smoke transport into the eastern United States, resulting in poor air quality and reduced visibility. Significant degradation of air quality was evident from PM2.5 surface measurements as the smoke plume moved southwards, which was confirmed ...

Shear localization of fcc high-entropy alloys

EPJ Web of Conferences, 2018
Dynamic behavior of the single phase (fcc) Al0.3CoCrFeNi and CoCrFeMnNi high-entropy alloys (HEAs) was examined. The combination of multiple strengthening mechanisms such as solid solution hardening, cutting forest dislocation, as well as mechanical nano-

Postfrontal Deep Convection Over the Southern Ocean and Orographic Precipitation Enhancement Over Tasmania

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The orographic precipitation enhancement (OPE) generated within wintertime post‐frontal air masses is a prominent climate feature of Tasmania. This study investigates a passage of a cold sector of a mid‐latitude cyclone over the Southern Ocean (SO) and Western Tasmania (WTAS) observed from 2100 UTC 11 July to 0300 UTC 13 July.

To Align or Not to Align? That Is the Question

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Previous studies have shown that vertically misaligned circulations are commonly found in weaker tropical cyclones (TCs) below hurricane strength, whereas TCs of hurricane intensity more typically exhibit vertically aligned vortices. Thus an important step in the TC intensification process is achieving a vertically aligned circulation.

Evaporation and Cold Pools Beneath Trade Cumulus Clouds

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The sources of air and water vapor in the tropical trade‐wind Atlantic subcloud boundary layer (SBL) are analyzed using in situ measurements of temperature, specific humidity, and stable water isotopologues (HDO and H218O) from shipboard observations in January‐February 2020.
