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 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 ...
