Abstract Rogue waves are dangerous ocean waves at least twice as high as the surrounding waves. Despite an abundance of studies conducting simulations or wave tank experiments, there is so far no reliable forecast for them. In this study, we use data

Until recently, our pure Python, primitive equation ocean model Veros has been about 1.5x slower than a corresponding Fortran implementation. But thanks to a thriving scientific and machine learning library ecosystem, tremendous speed-ups on GPU, and

The occurrence of extreme (rogue) waves in the ocean is for the most part still shrouded in mystery, as the rare nature of these events makes them difficult to analyze with traditional methods. Modern data mining and machine learning methods provide

A general circulation ocean model is translated from Fortran to Python. It is described how its code structure is optimized to exploit available Python utilities, remove simulation bottlenecks, and comply with modern best practices. Furthermore, supp
