Cold comfort for change: Stream mats as biological indicators of ecosystem processes in the McMurdo Dry Valleys, Antarctica

open access: yesJournal of Phycology, Volume 62, Issue 2, Page 261-292, April 2026.
Abstract Glacier‐fed streams (GFSs) make ideal systems for studying climate‐related changes. Some of the best‐studied GFSs are found in the McMurdo Dry Valleys (MDVs) of Antarctica, one of the Earth's coldest and driest deserts. Despite their harsh and isolated nature, MDV GFSs represent an oasis of life in a landscape visually devoid of it, with ...

Austral summer foehn winds over the McMurdo dry valleys of Antarctica from Polar WRF [PDF]

open access: yes, 2014
Foehn winds are a prominent feature of the McMurdo Dry Valleys (MDVs) climate, and are responsible for periods of strong winds and warming. The foehn mechanism determined from a case study presented in earlier work is shown here to be robust for a set of

Aerosol Effect on Orographic Clouds and Its Meteorological Feedback: A Numerical Case Study

open access: yesAtmospheric Science Letters, Volume 27, Issue 3, March 2026.
We investigate the aerosol effects on orographic clouds and its feedback on the surrounding meteorological environment. The simulations reveals that aerosols perturb the near‐storm thermodynamics via the “indirect microphysical effects”, resulting in lower humidity and higher temperature at lower levels of the lee side.

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.

Cotnari vineyard - a gift of hydraulic foehn?

open access: yes, 2014
Cotnari vineyard is the northernmost wine-growing vineyard of our country, located close enough to the northern limit of the expanding region of the grape vine. Within this study, we analyse one of the climatic factors that, in our view, contributes to

Spatial evolution of foehn flows in the Rhine Valley area: quantification using high resolution simulations

open access: yesMeteorologische Zeitschrift, 2004
The Rhine valley was one target area chosen during the Mesoscale Alpine Programme (MAP) field experiment to study Foehn flows. The dense data set available has allowed the computation and validation of high resolution simulations.

Case Study of Foehn Events Over Alborz Mountains in Iran

open access: yes, 2023
Warm and dry foehn winds can significantly affect human life in mountainous regions worldwide. Foehn’s features include rising temperature, dropping relative humidity, and a fixed direction high wind commencement. Iran, a mountainous country, is affected

Observations of foehn onset in the Southern Alps, New Zealand

open access: yes, 2002
Local scale windfield and air mass characteristics during the onset of two foehn wind events in an alpine hydro-catchment are presented. Grounding of the topographically modified foehn was found to be dependent on daytime surface heating and topographic ...

Multidecadal Foehn time series reconstruction using machine learning and ERA5 reanalysis data

open access: yes, 2020
Foehn has an impact on people living in mountainous regions through e.g., wildfires, agricultural conditions, and tourism. Currently, foehn time series are often short or available for well-investigated places only while long foehn time series at a fine ...
