Calculation Breakdown

  1. Applied FormulaCalculates the gradient Richardson number Ri comparing static buoyancy damping to vertical wind shear to predict clear-air turbulence (CAT) and Kelvin-Helmholtz billows.\text{Ri} = \frac{\frac{g}{\theta} \frac{\partial \theta}{\partial z}}{\left(\frac{\partial u}{\partial z}\right)^2 + \left(\frac{\partial v}{\partial z}\right)^2} < 0.25 \implies \text{CAT}
