Cloud-Capped Towers: Capturing Terrain Characteristics Using Topographic Functionals

Quaestiones Geographicae, 2015
We introduce three related mathematical measures of terrain based on a particularly elegant combination of relief and steepness, which we term omnidirectional relief and steepness (ORS). One measure, reduced ORS (RORS), is particularly suited to creating

Decoupled kinematics of two neighbouring permafrost creeping landforms in the Eastern Italian Alps [PDF]

, 2019
An overall acceleration of rock glacier displacement rates in the Alps has been observed in recent decades, with several cases of destabilization leading to potential geomorphological hazards.

Periglacial Puzzles: Unravelling Environmental Controls on Alpine Solifluction Lobe Dimensions and Shape

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Freeze–thaw processes cause periglacial creep (otherwise known as solifluction) which forms solifluction lobes. These are lobate features characterized by a steep riser (front) and a smooth tread (body). Despite the widespread occurrence of these lobes, the controls on their morphometry remain poorly understood. Research into solifluction lobe

Volcanic landforms

, 2001
Volcanic landforms are common features of the New Zealand environment. They originate by two major processes: first, by the eruption of various magmas onto the Earth's surface creating a wide array of landforms; and second, by largely physical, and to

Integrating SfM, LiDAR and TLS for High‐Resolution Monitoring of Palsa Surface Changes and Degradation Dynamics

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Understanding fine‐scale surface changes is crucial for quantifying ecosystem dynamics and detecting landscape changes. Palsas, comparably small peatland elevations with an ice‐rich permafrost core, undergo natural cycles of growth and degradation. They can also serve as indicators of climate change in subarctic regions. Because they typically

Applicability Assessment of ERA5 Surface Wind Speed Data Across Different Landforms in China

Atmosphere
Accurate surface wind speed data are vital for atmospheric science, climatology, and energy applications. European Centre for Medium-Range Weather Forecasts Reanalysis v.5 (ERA5), as one of the most widely used global reanalysis datasets, has ...

Electrical Resistivity Tomography for the 2D and 3D Investigation of Pingos and Permafrost Mounds in Northern Canada's Mountain and Coastland Areas

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Pingos and related permafrost mounds are widespread periglacial landforms in Arctic environments that are ice‐rich on the one hand and contain taliks on the other, making them vulnerable to climate change. So far, the interior, geophysical characteristics, and distribution of ground ice within these dome‐ or cone‐shaped features have not been ...
