OVERVIEW

Modeling the physical processes of deep overflow from regional seas.

(1) Physics of the overflow is based on the paper of Briegleb, Danabasoglu and Large (2010) (2) Geographic input data (I and J points) for each region is given by user at the Field Table. (3) Model can compute the overflow processes for many places. There is no maximum number of overflows. (4) Maximum production lines (or regions) in this code is ten. To get more, code needs to be written. (5) Main acronyms. src:source, int:interior, ent:entrainment, prd:production
