The signed wall-turbulence length formed from stress velocity and the vertical turbulent buoyancy flux. With upward buoyancy transport positive, stable cooling has and ; heating from below gives . The magnitude marks the transition between shear-dominated and buoyancy-dominated scaling.

The Monin–Obukhov length, often denoted as \(L\), is a key parameter in the study of atmospheric boundary layer meteorology. It represents a characteristic length scale that describes the vertical distribution of temperature and momentum in the atmospheric boundary layer, particularly under convective conditions. This length is crucial for understanding the balance between turbulence, buoyancy, and stratification in the atmosphere.
