Capturing the Multi‐Decadal Evolution of Glacier–Permafrost Interactions in a High‐Alpine Environment (Ritord, Western Swiss Alps)

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT This study investigates the multi‐decadal evolution of a glacier forefield under permafrost conditions in the Combins Massif (western Swiss Alps). A multi‐method approach based on historical and recent datasets is used to analyze its landform components.

BARREL Observations of Microburst Events With a Slowly‐Varying Component

Geophysical Research Letters
Electron microburst precipitation has been shown to have significant potential for depletion of the outer radiation belt. We present observations from the Balloon Array for Radiation belt Relativistic Electron Losses (BARREL) of six (five unique and one ...

Using ACIS on the Chandra X-ray Observatory as a particle radiation monitor

, 2010
The Advanced CCD Imaging Spectrometer (ACIS) is one of two focal-plane instruments on the Chandra X-ray Observatory. During initial radiation-belt passes, the exposed ACIS suffered significant radiation damage from trapped soft protons scattering off the

Climate change‐driven expansion of goosegrass highlights risks to global food production

Pest Management Science, EarlyView.
Climate change is expanding the climatic suitability of Eleusine indica into temperate agricultural regions, increasing its overlap with major soybean and maize production areas. These findings highlight a growing global threat to food security and the need for proactive weed management strategies.

Covariance of the intertropical discontinuity and African easterly jet in Sahelian wet and dry years

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Intertropical discontinuity and African easterly jet (AEJ) positions are strongly correlated, with a more pronounced linear relationship across wet years. Surface heat flux anomalies modify low‐level temperature and sensible heat flux gradients that shift the AEJ core south of the gradient maxima in both composites.

Lagrangian analysis of two flavours of Central European heatwaves: Formation under omega blocking versus initiation by subtropical ridges

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We investigate whether Central European heatwaves (HWs) forming under omega blocking differ from those enabled by subtropical ridges, in terms of both air‐mass origin and processes warming air parcels along their way. Using ERA5‐based backward trajectories and a Lagrangian temperature anomaly decomposition, we identify significant differences in the ...
