| 162 | !!1. According to Palma and Matano, 1998 "after ssh" is used. |
---|
| 163 | !! In ROMS and POM implementations, it is "now ssh". In the current |
---|
| 164 | !! implementation (tested only in the EEL-R5 conf.), both cases were unstable. |
---|
| 165 | !! So I use "before ssh" in the following. |

| 166 | !! |
---|
| 167 | !!2. We assume that the normal ssh gradient at the bdy is zero. As a matter of |

| 168 | !! fact, the model ssh just inside the dynamical boundary is used (the outside |
---|
| 169 | !! ssh in the code is not updated). |
