- gradient_richardson_number(T_top, T_bottom, P_top, P_bottom, U_top, U_bottom, V_top, V_bottom, delta_h)[source]
Formula for the gradient richardson number - related to the bouyant production or consumption of turbulence divided by the shear production of turbulence. Used to indicate dynamic stability
- Parameters:
T_top (ndarray) – Temperature at higher height. Used in the approximation of potential temperature derivative
T_bottom (ndarray) – Temperature at lower height. Used in the approximation of potential temperature derivative
P_top (ndarray) – Pressure at higher height. Used in the approximation of potential temperature derivative
P_bottom (ndarray) – Pressure at lower height. Used in the approximation of potential temperature derivative
U_top (ndarray) – Zonal wind component at higher height
U_bottom (ndarray) – Zonal wind component at lower height
V_top (ndarray) – Meridional wind component at higher height
V_bottom (ndarray) – Meridional wind component at lower height
delta_h (float) – Difference in heights between top and bottom levels
- Returns:
ndarray – Gradient Richardson Number
