Research Progress
2012.7.9
Based on the GDEMV3 monthly climatology temperature and salinity data files, the climatology file for IAS were constructed.
GDEMV3: horizontal resolution 0.25 degree 78 vertical standard levels from 0 to 6600m
To construct zeta, u, v, t, s, ubar, vbar
The level of no motion: 2000mCalculate dynamic height and then geostrophic velocity. Ekman flow is also added.Through vertical integration of velocity to get ubar, vbar.
Approach
Initial condition for zeta from GDEMV3
Initial condition for sst from GDEMV3
