The ocean circulation is driven by a combination of winds and surface buoyancy fluxes. We run a number of experiments with varied surface forcings and look at the spatial variations in ocean circulation on short and long time-scales.

Flux forced - varying wind stress by a certain factor #38

Open dhruvbhagtani opened 2 years ago

dhruvbhagtani commented 2 years ago

We have successfully created a set of simulations where changing one doesn't affect the other. In the following issue, we discuss a set of experiments where we change the wind stress, keeping the heat flux the same, as shown in the animation. We run the control, 0.5xS (0.5 times the wind stress compared to control) and 1.5xS (1.5 times the wind stress compared to control) for 100 years each.

We observe a systematic increase in gyre strength as we increase the wind stress curl. This is consistent with the Sverdrup theory:

Sure. But not proportional as it seems. I mean, 53 ≠ 44 x 1.5 and 32 ≠ 44 x 0.5

Suggestion: 32Sv, 44Sv, 53Sv would be great for the figure purposes. You don't need much more accuracy. Anyway how you measure these transports is a bit arbitrary.

Figures look great!

Another minor point of order from the ocd figure-critic is that the colorbar should have as many levels as the number of levels in the figures. Then it's obvious what value corresponds to which contour.

navidcy commented 2 years ago

What are these red contours?

dhruvbhagtani commented 2 years ago

Good point. The red contours are same for all the cases - it shows the extent of the North Atlantic subtropical gyre in the control run. We superimpose this contour on all cases to understand the spatial differences between gyres of different experiments.

Also, I have updated my previous comment to make the colorbar consistent with my plot.
