Værmeldingsmodeller
Værmeldingsmodeller, also known as numerical weather prediction (NWP) models, are sophisticated computer programs that use mathematical equations to simulate the behavior of the Earth's atmosphere. These models take current atmospheric conditions as input, such as temperature, pressure, humidity, and wind speed, and then forecast how these variables will change over time. The foundation of these models lies in the laws of physics, particularly fluid dynamics and thermodynamics, which govern atmospheric processes.
The process begins with data assimilation, where vast amounts of observational data from various sources, including
Different NWP models exist, varying in their resolution (the size of the grid cells), the complexity of
