Reconstructing fine-scale 3D wind fields with terrain-informed machine learning [PDF]
Fine-scale near-surface wind field prediction is essential for a wide range of applications. However, most operational and AI-based weather models operate at kilometer-scale resolution, where terrain-induced wind features such as slope jets, flow ...

Long-range transport of terrain-induced turbulence from high-resolution numerical simulations [PDF]
Over complex terrain, an important question is how various topographic features may generate or alter wind turbulence and how far the influence can be extended downstream.
