Meteorological Research Institute: Model MRI GCM-IIb (4x5 L15) 1995
Model Designation
MRI GCM-IIb (4x5 L15) 1995Model Lineage
The model is identical to AMIP baseline model MRI GCM-II (4x5 L15) 1993, except for different initial conditions and a change in a gravity-wave drag factor.Model Documentation
Cf. Kitoh et al. (1995)[10] for a discussion of results of the AMIP integration made with this model, and the appendix of the same paper for differences from the results of the baseline model.Numerical/Computational Properties
Initialization
Initial conditions of model atmosphere, soil temperature and moisture, and snow depth/cover for the repeated AMIP experiment were taken from the last time step of the AMIP simulation with the baseline model.Dynamical/Physical Properties
Gravity-wave Drag
Orographic gravity-wave drag is simulated in the same way as in the baseline model, except that the gravity-wave generation factor kappa is increased by a factor of 2 (from 6.0 x10 ^-6 m^-1 to 1.2 x 10^-5 m^-1). This change produces a substantially different stratospheric zonal wind climatology and temperature structure (cf. the appendix of Kitoh et al. 1995 [10])Return to Model Table of Contents
