13	! ABSTRACT:
14	! MYJ UPDATES THE TURBULENT KINETIC ENERGY WITH THE PRODUCTION/
15	! DISSIPATION TERM AND THE VERTICAL DIFFUSION TERM
16	! (USING AN IMPLICIT FORMULATION) FROM MELLOR-YAMADA
17	! LEVEL 2.5 AS EXTENDED BY JANJIC. EXCHANGE COEFFICIENTS FOR
18	! THE SURFACE AND FOR ALL LAYER INTERFACES ARE COMPUTED FROM
19	! MONIN-OBUKHOV THEORY.
20	! THE TURBULENT VERTICAL EXCHANGE IS THEN EXECUTED.
