Abstract:

Determination of the stability regime is a basic approach in any investigation of atmospheric turbulence. The establishment of stability criteria in the boundary layer is usually accomplished by use of the nondimensional Richardson number. The computation of accurate Richardson numbers is shown to be adversely affected by a number of factors including the choice of vertical gradients, the terrain, spacing of instruments, and heterogeneous profiles of wind and temperature.
