New Zealand Journal of Geology and Geophysics, Volume 68, Issue 5, Page 1232-1248, December 2025.ABSTRACT Loess is a patchy but widespread constituent of East and Central Otago (South Island, New Zealand), where it attests to extensive aerial mobilisation and deposition of fine‐grained sediment. While most Otago loess deposits formed in the Pleistocene, we examine massive, fine‐grained but clay‐altered, Pliocene beds in Central Otago that may be ...

Föhn winds on South Georgia and their impact on regional climate [PDF]
, 2015 South Georgia is a small and mountainous island, located in the remote Southern Ocean. The island’s subantarctic climate is controlled by its location and steep orography; with 19 peaks over 2000m and situated within a belt of strong westerly winds South

Mapping Radar Glacier Zones and Dry Snow Line in the Antarctic Peninsula Using Sentinel-1 Images
Remote Sensing, 2017 Surface snowmelt causes changes in mass and energy balance, and endangers the stabilities of the ice shelves in the Antarctic Peninsula (AP). The dynamic changes of the snow and ice conditions in the AP were observed by Sentinel-1 images with a spatial ...

Evaluating machine‐learning models for wind‐speed downscaling from ECMWF‐IFS data
Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 773, October 2025 Part B.We benchmark recent machine‐learning methods for downscaling wind speeds from a low‐resolution 9‐km model input to 1‐km predictions. We include recent super‐resolution approaches and transformer‐based architectures and propose Windflow‐SRnet. The models are trained with input data from the ECMWF‐IFS numerical weather model to predict label data from ...

Antum Crater: A Window Into Ganymede's Icy Evolution
Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.Abstract Located within the extensive dark terrain of Marius Regio, in the anti‐Jovian trailing quadrant of Ganymede, Antum crater is marked by dark‐rayed ejecta that obscure older features and reshape the surrounding landscape. This study investigates Antum and its geological context using optical and infrared data from the Voyager and Galileo ...

Topographic effects of Svalbard on warm and moist air intrusions into the Central Arctic [PDF]
Weather and Climate DynamicsWarm air intrusions (WAIs) along the North Atlantic pathway are key drivers of warm extremes in the central Arctic. The Svalbard archipelago acts as a major topographic barrier in the middle of this gateway, but its role in modulating WAIs and their ...
