3.1 Modern specified SST versus Modern predicted SST
2.1.1 Sea surface temperature
| Modern specified SST | Modern predicted SST |
|---|
 |

"Specified SST" means no temporal change. However, "specified SST" change based on time of year, e.g. seasonal change. Specified sea surface temperature is higher than predicted SST. You can confirm effects of this difference in water content, evaporation, precipitation, and snow cover.
3.1.2 Ocean ice cover
| Modern specified SST | Modern predicted SST |
|---|
 |
 |
Ocean ice cover is constant in the "specified SST". "Modern specified SST," means not only sea surface temperature but also ocean ice cover is specified.
3.1.3 other elements
Other elements show seasonal and inter-annual variability but almost constant. That is because we keep climate forcing factors such as solar radiation incident on planet and concentrations of greenhouse gases. We call these experiments as control runs and compare with other experiment run in that we change the climate forcing factors.
