Advancing the Capabilities of Numerical Weather Prediction - On the Utility of Individual Tendency Output
Kähnert, Marvin (Doctoral thesis, 2022-11-18)Parametrisering i numeriske værmodeller representerer finskalaprosesser i atmosfæren på subgridnivå. Disse atmosfæriske prosessene inkluderer turbulens, stråling og dråpeformasjon i skyer. Enhver parametrisering er en ... -
On the utility of individual tendency output: Revealing interactions between parameterized processes during a marine cold air outbreak
Kähnert, Marvin; Sodemann, Harald; de Rooy, Wim; Valkonen, Teresa Maaria (Journal article; Peer reviewed, 2021)Forecasts of marine cold air outbreaks critically rely on the interplay of multiple parameterization schemes to represent subgrid-scale processes, including shallow convection, turbulence, and microphysics. Even though ... -
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 ...
