The Model (1)
History
Developed from MICOM version 2.8
See Bleck (1998) for a description of MICOM
Hybrid coordinate scheme used in HYCOM
Model equations written in generalized vertical coordinates
Originally used in the Bleck and Boudra (1981) quasi-isopycnic
model
Numerical schemes could not handle zero thickness layers
Minimum layer thickness was enforced
» The vertical coordinate became non-isopycnic in regions
where the layers became too thin
A hybrid (isentropic-sigma) vertical coordinate was used in the
atmospheric model of Bleck and Benjamin (1993)
The HYCOM isopycnic-level-sigma vertical coordinate scheme
is an adaptation and extension of the Bleck/Benjamin algorithm
