Radar measurements of blowing snow off a mountain ridge
Michael Lehning, Wolf Hendrik Huwald, Josué Etienne Gehring, Benjamin Andreas Walter
Modelling and forecasting wind-driven redistribution of snow in mountainous regions with its implications on avalanche danger, mountain hydrology or flood hazard is still a challenging task often lacking in essential details. Measurements of drifting and b ...
2020Five-minute average horizontal wind velocity data combined from both sensors (which has been corrected for air-flow distortion) from the Antarctic Circumnavigation Expedition (ACE) 2016/2017 legs 0 to 4.
Julia Schmale, Jenny Thomas, Sebastian Johannes Heinz-Josef Landwehr
Dataset abstract The horizontal wind velocity data from the Antarctic Circumnavigation Expedition (ACE) 2016/2017 legs 0 to 4 has been corrected for air-flow distortion. The measurements from both the port and starboad side anemometer were ...
2020Cohesion-Induced Enhancement of Aeolian Saltation
Michael Lehning, Johan Alexandre Philippe Gaume, Francesco Comola
The wind-driven saltation of granular material plays a key role in various geophysical processes on Earth, Mars, Venus, and Titan. Although interparticle cohesion is known to limit the number of grains lifted from the surface through aerodynamic entrainmen ...
AMER GEOPHYSICAL UNION2019Linearity versus non-linearity in high frequency multilevel wind time series measured in urban areas
Dasaraden Mauree, Fabian Guignard, Mohamed Laib
In this paper, high frequency wind time series measured at different heights from the ground (from 5.5 to 25.5 meters) in an urban area were investigated. The spectrum of each series is characterized by a power-law behaviour at low frequency range, with a ...
2019Machine learning and geographic information systems for large-scale wind energy potential estimation in rural areas
Jean-Louis Scartezzini, Dasaraden Mauree, Dan Assouline, Nahid Mohajeri Pour Rayeni
Clean, safe, affordable and available in the long-term, wind is one of the most promising sources of renewable energy. Its optimized and profitable use, however, requires an estimation of the potential in locations of interest, given its very volatile beha ...
IOP2019Short-Term Forecasting of Wake-Induced Fluctuations in Offshore Wind Farms
The increasing share of offshore wind energy traded at the spot market requires short term wind direction forecasts to determine wake losses and increased power fluctuations due to multiple wakes in certain wind directions. The information on potential pow ...
2019Design and Performance Evaluation of an Algorithm Based on Source Term Estimation for Odor Source Localization
Alcherio Martinoli, Ali Marjovi, Faezeh Rahbar
Finding sources of airborne chemicals with mobile sensing systems finds applications across safety, security, environmental monitoring, and medical domains. In this paper, we present an algorithm based on Source Term Estimation for odor source localization ...
2019Force measurement of a gas-assisted atomization using an impulse probe
The main objective of this study was to develop further insight into the mass flux characterization of an effervescent atomization. The spray is injected through an industrial effervescent nozzle, and is measured using a newly developed coupled PDPA + IS m ...
PERGAMON-ELSEVIER SCIENCE LTD2019Wind-packing of snow: How do wind crusts form?
Wind-packing of snow is the process responsible for the formation of wind slabs and wind crusts. These are hard layers of well-sintered snow often found in the snowpack in mountains as well as in polar regions. Wind-packing affects the local mass balance, ...
EPFL2018Investigation of a wind-packing event in Queen Maud Land, Antarctica
Michael Lehning, Nander Wever, Christian Gabriel Sommer, Charles Fierz
Surface snow in polar and mountainous regions is often mobile and this mobility influences surface mass balance and isotopic composition before final deposition, which is poorly understood thus far. In December 2016 and January 2017, during a field campaig ...
