The article describes a model for wind and turbulence near the Earth's surface. It looks at how different factors like surface roughness and stability affect the way wind behaves. The researchers used mathematical equations to show how wind changes with height and stability. They found that in very stable conditions, the usual wind patterns don't apply, and large-scale weather systems play a bigger role. This model helps us understand how wind and turbulence work close to the ground, which is important for things like predicting weather patterns and designing buildings.
