The model extends the vertical domain and resolution of the AMIP
baseline model YONU Tr5.1 (4x5 L5) 1994 by the inclusion of 2 more
vertical levels. The method of obtaining surface values of air
temperature and moisture for purposes of calculating surface fluxes is
also changed.
The dynamical structure and numerics of the YONU model are essentially
those of the Meteorological Research Institute (MRI) model ; however,
the YONU and MRI model differ substantially in their treatment of
radiation, cloud formation, and surface processes. Some of the YONU
model surface schemes also are derived from those of the two-level
Oregon State University model (cf. Ghan et al. 1982).
For the PMIP, YONU consists of runs 6 and 0.
