- **t613 (red solid curve, run by K. Wyser)** is the CMIP6 EC-Earth3-Veg r1 historical member covering 1850-2014 (only the period 1950-2014 is shown here);
|
|
|
|
|
- **D000 (blue solid curve)** is the **control** run starting from year 2014 of the t613 experiment with 2000-year constant atmospheric forcing; this control run is 200 years long; all other experiments start somewhere in the middle of this control run;

I also plot **observations and reanalysis as solid black curves** in my sea-ice plots, in order to compare the model outputs to the 'real world'.

In this set of experiments, I restored the sea-surface temperature (SST) in a selected region to a certain value and compared the results of these sensitivity experiments to a control run. The control run starts from the year 2014 of the CMIP6 EC-Earth3-Veg r1 historical member, uses a 2000-year constant atmospheric forcing and is 200 years long. The sensitivity experiments all start from the year 2130 of the control run (year 117 if we consider the starting year to be 1) and are 50 years long.

Here are the different model experiments with the corresponding color in the plots below:
|
|
|
|
- **t613 (red solid curve, run by K. Wyser)** is the CMIP6 EC-Earth3-Veg r1 historical member covering 1850-2014 (only the period 1950-2014 is shown here);
|
|
|
|
- **D000 (blue solid curve)** is the **control** run starting from year 2014 of the t613 experiment with 2000-year constant atmospheric forcing; this control run is 200 years long; all the sensitivity experiments start in year 2130 of this control run (year 117 if we consider the starting year to be 1) and are 50 years long;
|
|
|
|
- **D012 (green dashed curve)** starts in year 2130 of the control run (D000); the only change compared to the control run is that the SST is restored to the mean climatology increased by 3°C in the North Atlantic Ocean (40-80N, 40W-20E);
|
|
|
|
- **D013 (red dashed curve)** is similar to D012, except that the SST is restored to the mean climatology increased by 1°C;
|
|
|
|
- **D014 (gray dashed curve)** is similar to D012, except that the SST is restored to the mean climatology increased by 5°C;
|
|
|
|
- **D005 (orange dashed curve)** is similar to D004, except that the **bottom drag coefficient** is **20 times higher** than the control run;
|
|
|
|
- **D007 (magenta dashed curve)** starts in year 2130 of the control run and is only 10 years long; the only change compared to the control run is the **vertical eddy diffusivity**, which is **2 times higher**;
|
|
|
|
- **D008 (cyan dashed curve)** starts in year 2130 of the control run; the only change compared to the control run is the **horizontal eddy diffusivity**, which is **2 times higher**;
|
|
|
|
- **D009 (brown dashed curve)** starts in year 2130 of the control run; the only change compared to the control run is the **surface minimum value of turbulent kinetic energy (TKE)**, which is **2 times higher**;
|
|
|
|
- **D010 (yellow dashed curve)** starts in year 2130 of the control run; this experiment **combines** the changes of experiments D004 (bottom drag x 2), D008 (horizontal diffusivity x 2) and D009 (min. value of TKE x 2).
