In this section, the standard diagnostics are applied to GA6 output to identify the model biases in simulating the tropical climate during DJF and JJA seasons.
Experimental Design
=Model= | =Resolution\(grid points)= | =Vertical\Resolution= | =Start Date= | =SST &\Sea ice= | =Period= |
---|---|---|---|---|---|
UM8.6 | =N96\(192x145)= | =85 levels= | =1 September\1995= | =Observed monthly\(AMIP)= | 1996-2010\(15 years) |
UM8.6 | =N216\(432x325)= | =85 levels= | =Observed monthly\(AMIP)= | 1996-2010\(15 years) |
Observed Dataset
The following dataset are used to evaluate the performance of the model and to identify the model biases.
=Dataset= | =Variables= | =Horizontal Resolution= | =Vertical\Resolution= | =Period= |
---|---|---|---|---|
=GPCP= | =Rainfall= | =1 degree x 1 degree= | # - | =1997-2010= |
=AVHRR= | =Outgoing Longwave\Radiation (TOA)= | =2.5 degree x 2.5 degree= | # - | =1996-2010= |
=ERA-interim\(ERAI)= | =u,v,T,q,relative humidity= | =T255(~80 km)= | =60 levels= | =1996-2010= |
Level 1 Diagnostics
- Seasonal Mean Precipitation
- Seasonal Mean Outgoing Longwave Radiation at TOA
- __Seasonal Mean Zonal Wind at 850 hPa __
- __Seasonal Mean Zonal Wind at 200 hPa __
- __Seasonal Mean Velocity Potential and Divergent Wind at 200 hPa __
- __Seasonal Mean Zonal Wind Profile __
- __Seasonal Mean Temperature Profile __
- __Seasonal Mean Specific Humidity Profile __
- __Seasonal Mean Relative Humidity Profile __
