Snowfall deposition in mountainous terrain: a statistical downscaling scheme from high-resolution model data on simulated topographies
One of the primary causes of non-uniform snowfall deposition on the ground in mountainous regions is the preferential deposition of snow, which results from the interaction of near-surface winds with topography and snow particles. However, producing high-r ...
Lausanne2024Influence of sun cups on surface albedo of wet Alpine snowpack
Michael Lehning, Mathias Thierry Pierre Bavay, Francesca Carletti
In high elevation Alpine areas, characterised by high snow accumulation and radiation-driven melt processes, the formation of peculiar ablation features called sun cups can be observed. Sun cups likely influence the energy and mass balance of the wet snowp ...
2024Brown carbon absorption in the Mediterranean basin from local and long-range transported biomass burning air masses
This study examines the impact of light absorption from biomass burning (BB) brown carbon (BrC) in the Mediterranean basin from local and distant fire incidents during a typical fire season in August 2019 and under severe fire activity in August 2021. The ...
PERGAMON-ELSEVIER SCIENCE LTD2023Natural slicks on Lake Geneva: From small-scale effects to large-scale formation and distribution
Low wind speeds (< 4 m/s) are ubiquitous in many water bodies, yet the physical processes occurring at the air-water interface in this range are poorly understood. A notable example is smooth patches on the water surface, known as natural slicks, formed wh ...
EPFL2023Reinforcement Learning for Outdoor Balloon Navigation: A Successful Controller for an Autonomous Balloon
Autonomous ballooning allows for energy-efficient long-range missions but introduces significant challenges for planning and control algorithms, due to their single degree of actuation: vertical rate control through either buoyancy or vertical thrust. Late ...
