Cerebrovascular flow‐mediated dilation in humans: Methodological challenges, physiological interpretation and future integrations

Experimental Physiology, Volume 111, Issue 11, Page 5061-5073, 1 November 2026.
Abstract Arterial shear‐mediated vasodilation is a well‐established measure of endothelial function and serves as a critical biomarker for cardiovascular disease risk. Endothelial function can be measured using a variety of experimental methodologies; however, the most widely adopted technique is ultrasound‐based flow‐mediated dilation (FMD), in which ...

Acoustic‐Seismic Coupling Signals From Aircraft Reveal Firn‐Ice Transition and Near‐Surface Elastic Structure of Antarctic Ice

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Predicting the response of Antarctic ice to climate change requires detailed knowledge of its shallow structure, but direct measurements are challenging. Traditional seismic surveys are logistically demanding, and surface remote sensing provides limited information about subsurface layers.

Coherent Turbulence Signatures Preceding Warm Rain Events From Collocated Cloud Radar and Wind Profiler Observations Across China

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Warm rain is plagued by a longstanding droplet growth bottleneck, one that turbulence may alleviate by enhancing droplet coalescence in the late condensation phase. Nevertheless, empirical observational support from multiple sites remains scarce. Here, we combine collocated nationwide millimeter cloud radars, radar wind profilers, Himawari‐8/9

Surface‐Constrained Reconstruction of Spatiotemporal Turbulence Dissipation in the Convective Boundary Layer Using Physics‐Guided Machine Learning

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Turbulence dissipation rate (EDR) governs the conversion of turbulent kinetic energy to heat and thereby controls vertical mixing, transport, and energy exchange in the convective boundary layer (CBL). The spatiotemporal structure of EDR remains poorly constrained, as observations are limited to point measurements or sparse vertical profiles ...

How Can the Latent Heat Entrainment Flux in the Convective Boundary Layer be Characterized?

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract A proposed theoretical description of the latent heat entrainment flux at the top of a convective boundary layer (CBL) was tested. It is related to the vertical velocity scale times the ratio of the water vapor mixing ratio (WVMR) gradient to the Brunt‐Väisälä frequency. This relation was tested with different LiDAR and radiosonde measurements.
