To take advantage of a `high end' turbulence parameterization |
|
|
(and convection parameterization), the vertical resolution near the surface |
|
|
must be increased substantially as compared to the vertical resolution needed |
|
|
aloft. This cannot be accomplished if the high end physics is computed using |
|
|
the $p^*$ coordinate currently in use in the MIT gcm. |
