Mineralogy of Soil‐Free Bare Crusts on Native Dryland Plant Habitats in Mackenzie Basin, South Island, New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Late Cenozoic silty and sandy sediments in the semi‐arid Mackenzie basin have been eroded and redeposited almost entirely from nearby Mesozoic greywacke basement. Fine (commonly micron scale) phyllosilicate flakes, including clays, are randomly distributed and randomly oriented, and the sediments are porous.

Dust Deposition and Loess Accretion in New Zealand's South Island: Examining Links between Cold‐Climate Processes and Dust Production

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
We compared temporal variability in dust and loess accretion in New Zealand's South Island with glacial activity in the central Southern Alps, considered the main mechanism of silt production, in (i) a proximal loess deposit at Barrhill, Rakaia River and (ii) a distal dust record from a peat mire in Central Otago.

Glacier‐Atmosphere Interactions and Feedbacks in High‐Mountain Regions ‐ A Review

open access: yesReviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Mountain glaciers are among the natural systems most vulnerable to climate change. However, their interactions with the atmosphere are complex and not fully understood. These interactions can trigger rapid adjustments and climate feedbacks that either amplify or attenuate atmospheric signals, influencing both glacier response and large‐scale ...

Variation of the aerosol stratification over the Rhine Valley during Foehn development: a backscatter lidar study

open access: yesMeteorologische Zeitschrift, 2004
The vertical aerosol stratification within and above the Rhine Valley was studied with a backscatter lidar during FORM (Foehn in the Rhine Valley during MAP) IOPs 4-5, October 1-3, 1999. The lidar site was in Tr¨ubbach, 9° 28 E, 47° 04 N, 490 m asl.

Numerical simulation study of the effects of foehn winds on white head incidences in Yamagata Prefecture, Japan

open access: yesMeteorological Applications, 2021
Numerous studies have elucidated that white heads and chalky rice are caused by hot, dry and strong winds at night. However, these studies have only used synoptic weather charts and near‐surface observation data to confirm the role of foehn in white head

Evaluating Atmospheric River Impacts on Energy and Moisture Transport in the Arctic Using Different Detection Algorithms

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract Atmospheric rivers (ARs) significantly impact the Arctic climate system by enhancing atmospheric heat and moisture transport and altering the local energy budget. Developing AR detection tools (ARDTs) is critical yet challenging. This study evaluates 12 ARDTs in the Arctic to assess their performance in representing atmospheric heat ...

Rapid and sudden advection of warm and dry air in the Mediterranean Basin [PDF]

open access: yes, 2014
Rapid advection of extremely warm and dry air is studied during two events in the Mediterranean Basin. On 27 August 2010 a rapid advection of extremely warm and dry air affected the northeast Iberian Peninsula during a few hours.

Enhanced Adiabatic Heating Drives Faster Warming of Early Summer Hot Extremes in North China

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract North China has recently seen frequent hot days above 35°C or even 40°C before or at the very beginning of June. This raises a concern about the changing seasonality of exceptional hot extremes in the region which might leave population there underprepared.
