GSD mym_turbulence General Algorithm

Two subroutines mym_level2() and mym_length() are called within this subrouine to collect variable to carry out successive calculations:

• mym_level2() calculates the level 2 nondimensional wind shear \(G_M\) and vertical temperature gradient \(G_H\) as well as the level 2 stability functions \(S_h\) and \(S_m\).
• mym_length() calculates the mixing lengths.
• The stability criteria from Helfand and Labraga (1989) are applied.
• The stability functions for level 2.5 or level 3.0 are calculated.
• If level 3.0 is used, counter-gradient terms are calculated.
• Production terms of TKE, \(\theta^{'2}\), \(q^{'2}\), and \(\theta^{'}q^{'}\) are calculated.
• Eddy diffusivity \(K_h\) and eddy viscosity \(K_m\) are calculated.
• TKE budget terms are calculated (if the namelist parameter bl_mynn_tkebudget is set to True)
