First high-resolution look at the quiet Sun with ALMA at 3 mm [PDF]

, 2018
We present an overview of high resolution quiet Sun observations, from disk center to the limb, obtained with the Atacama Large mm and sub-mm Array (ALMA) at 3 mm. Seven quiet Sun regions were observed with resolution of up to 2.5" by 4.5".

The Zonal Wave‐3 Mode Impacts Antarctic Dense Water Formation

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract At the Antarctic margins, dense water masses form as sea ice develops, driving the Antarctic branch of the global meridional overturning circulation. Previous studies found that large‐scale climate modes such as the Southern Annular Mode and El Niño Southern do not fully account for the interannual variability of dense water formation.

Connecting the Atlantic Meridional Overturning Circulation to the Southern Ocean Following the Closure of Equatorial Seaways During the Cenozoic

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Global ocean circulation regulates climate and has undergone significant changes over the Cenozoic. Today, the Atlantic Meridional Overturning Circulation (AMOC) is driven by North Atlantic Deep Water (NADW) formation and Southern Ocean upwelling.

Growth Rate and Energy Dissipation in Wind‐Forced Breaking Waves

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract We investigate the energy growth and dissipation of wind‐forced breaking waves at high wind speed using direct numerical simulations of the coupled air–water Navier–Stokes equations. A turbulent wind boundary layer drives the growth of a pre‐existing narrowband wave field until it breaks, transferring energy into the water column.

Deriving the radial distances of wide coronal mass ejections from elongation measurements in the heliosphere - Application to CME-CME interaction [PDF]

, 2009
We present general considerations regarding the derivation of the radial distances of coronal mass ejections (CMEs) from elongation angle measurements such as those provided by SECCHI and SMEI, focusing on measurements in the Heliospheric Imager 2 (HI-2)

A Fast Analytical Model for the Complete Radial Structure of Tropical Cyclone Low‐Level Wind Field

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract A tropical cyclone (TC) can generally be divided into three regions: inner core with vigorous convection, intermediate region with intermittent convection, and far outer region with less convective activity. The different physics in these three regions suggest correspondingly different wind structure models. In this study, we combine the inner‐

Comparison of Solar Fine Structure Observed Simultaneously in Ly-{\alpha} and Mg II h

, 2017
The Chromospheric Lyman Alpha Spectropolarimeter (CLASP) observed the Sun in H I Lyman-{\alpha} during a suborbital rocket flight on September 3, 2015.

A semi‐analytical Bayesian estimate retrieval algorithm for the inversion of remote‐sensing reflectance in optically deep and shallow waters

Limnology and Oceanography: Methods, Volume 24, Issue 1, January 2026.
Abstract The inverse problem in remote sensing of aquatic environment consists in retrieving optically significant constituents (OSCs) from a spectral measurement of the remote sensing reflectance (Rrs).Optically significant constituent includes chlorophyll a concentration (Chl a), a proxy of phytoplankton biomass, absorption of colored detrital matter

Consistency of holonomy-corrected scalar, vector and tensor perturbations in Loop Quantum Cosmology

, 2012
Loop Quantum Cosmology yields two kinds of quantum corrections to the effective equations of motion for cosmological perturbations. Here we focus on the holonomy kind and we study the problem of the closure of the resulting algebra of constraints.

Physical Processes Driving Carbon Subduction in the Southern Ocean in an Eddy‐Permitting Model

Global Biogeochemical Cycles, Volume 40, Issue 1, January 2026.
Abstract The Southern Ocean south of 35°S represents a small source of natural inorganic carbon for the atmosphere but a major sink of anthropogenic carbon. The magnitude of the inorganic carbon sink, and the sequestration of inorganic and organic carbon strongly depend on the rate at which they are subducted below the mixed layer.
