Extreme Precipitation in Nepal. Trends and Key Processes
Bohlinger, Patrik (Doctoral thesis, 2018-03-21)Nepal is located at the rim of the Himalayas and houses the highest mountains of the world. Owing to the complex topography and a seasonal monsoon climate, Nepal experiences precipitation events of considerable intensity. ... -
A general framework to obtain seamless seasonal–directional extreme individual wave heights—Showcase Ekofisk
Bohlinger, Patrik; Economou, Theodoros; Aarnes, Ole Johan; Malila, Mika Petteri; Breivik, Øyvind (Journal article; Peer reviewed, 2023)Extreme wave climate provides the basis for safe design of offshore structures and is crucial for planning and executing offshore operations. Covariate modeling of extremes significantly enriches and improves estimates of ... -
The Impact of a Reduced High-Wind Charnock Parameter on Wave Growth With Application to the North Sea, the Norwegian Sea, and the Arctic Ocean
Breivik, Øyvind; Carrasco, Ana; Haakenstad, Hilde; Aarnes, Ole Johan; Behrens, Arno; Bidlot, Jean-Raymond; Björkqvist, Jan-Victor; Bohlinger, Patrik; Furevik, Birgitte Rugaard; Staneva, Joanna; Reistad, Magnar (Journal article; Peer reviewed, 2022)As atmospheric models move to higher resolution and resolve smaller scales, the maximum modeled wind speed also tends to increase. Wave models tuned to coarser wind fields tend to overestimate the wave growth under strong ... -
Nora3: A nonhydrostatic high-resolution hindcast of the North sea, the Norwegian sea, and the Barents sea
Haakenstad, Hilde; Breivik, Øyvind; Furevik, Birgitte Rugaard; Reistad, Magnar; Bohlinger, Patrik; Aarnes, Ole Johan (Journal article; Peer reviewed, 2021)The 3-km Norwegian Reanalysis (NORA3) is a 15-yr mesoscale-permitting atmospheric hindcast of the North Sea, the Norwegian Sea, and the Barents Sea. With a horizontal resolution of 3 km, the nonhydrostatic numerical weather ... -
A novel approach to computing super observations for probabilistic wave model validation
Bohlinger, Patrik; Breivik, Øyvind; Economou, Theodoros; Müller, Malte (Peer reviewed; Journal article, 2019-07)In the field of wave model validation, the use of super observations is a common strategy to smooth satellite observations and match the simulated spatiotemporal scales. An approach based on averaging along track is widely ... -
Resolving regions known for intense wave–current interaction using spectral wave models: A case study in the energetic flow fields of Northern Norway
Halsne, Trygve; Bohlinger, Patrik; Christensen, Kai Håkon; Carrasco, Ana; Breivik, Øyvind (Journal article; Peer reviewed, 2022)Oceanic current forcing in spectral wave models have recently been demonstrated to have a large impact on wave heights at scales between one and up to several hundred kilometers. Here we investigate the impact of such ... -
Synoptic Conditions and Moisture Sources Actuating Extreme Precipitation in Nepal
Bohlinger, Patrik; Sorteberg, Asgeir; Sodemann, Harald (Peer reviewed; Journal article, 2017-12)Despite the vast literature on heavy‐precipitation events in South Asia, synoptic conditions and moisture sources related to extreme precipitation in Nepal have not been addressed systematically. We investigate two types ... -
Wave measurements using open source ship mounted ultrasonic altimeter and motion correction system during the one ocean circumnavigation
Ølberg, Judith Thu; Bohlinger, Patrik; Breivik, Øyvind; Christensen, Kai Håkon; Furevik, Birgitte Rugaard; Hole, Lars Robert; Hope, Gaute; Jensen, Atle; Knoblauch, Fabian; Nguyen, Ngoc Thanh; Rabault, Jean (Journal article; Peer reviewed, 2024)This study reviews the design and signal processing of ship borne ultrasonic altimeter wave measurements. The system combines a downward facing ultrasonic altimeter to capture the sea surface elevation as a time series, ...
