Analysis of the vertical temperature structure in the Bergen valley, Norway, and its connection to pollution episodes
Wolf, Tobias; Esau, Igor; Reuder, Joachim (Peer reviewed; Journal article, 2014-09)The vertical temperature profile in the lowest 1000m of the atmosphere determines a number of important physical processes and meteorological phenomena such as high concentrations of anthropogenic air pollutants in urban ... -
The Departure from Mixed-Layer Similarity During the Afternoon Decay of Turbulence in the Free-Convective Boundary Layer: Results from Large-Eddy Simulations
Elguernaoui, Omar; Reuder, Joachim; Li, Dan; Maronga, Bjørn; Bakhoday Paskyabi, Mostafa; Wolf, Tobias; Esau, Igor (Journal article; Peer reviewed, 2023)This study analyses the departure of the velocity-variances profiles from their quasi-steady state described by the mixed-layer similarity, using large-eddy simulations with different prescribed shapes and time scales of ... -
Knowledge Gaps and Impact of Future Satellite Missions to Facilitate Monitoring of Changes in the Arctic Ocean
Lucas, Sylvain; Johannessen, Johnny Andre; Cancet, Mathilde; Pettersson, Lasse H; Esau, Igor; Rheinlænder, Jonathan Winfield; Ardhuin, Fabrice; Chapron, Bertrand; Korosov, Anton; Collard, Fabrice; Herlédan, Sylvain; Olason, Einar; Ferrari, Ramiro; Fouchet, Ergane; Donlon, Craig (Journal article; Peer reviewed, 2023)Polar-orbiting satellite observations are of fundamental importance to explore the main scientific challenges in the Arctic Ocean, as they provide information on bio-geo-physical variables with a denser spatial and temporal ... -
Spatial heterogeneity of greening and browning between and within bioclimatic zones in northern West Siberia
Miles, Victoria; Esau, Igor (Journal article; Peer reviewed, 2016-10-26)Studies of the normalized difference vegetation index (NDVI) have found broad changes in vegetation productivity in high northern latitudes in the past decades, including increases in NDVI (‘greening’) in tundra regions ... -
Spatial variability of nocturnal stability regimes in an operational weather prediction model
Kähnert, Marvin; Sodemann, Harald; Remes, Teresa Maaria; Fortelius, Carl; Bazile, Eric; Esau, Igor (Journal article; Peer reviewed, 2022)Forecast errors in near-surface temperatures are a persistent issue for numerical weather prediction models. A prominent example is warm biases during cloud-free, snow-covered nights. Many studies attribute these biases ...
