Fig. 2: El Niño-Southern Oscillation in dynamic and slab oceans.
From: Ocean dynamics shape marine heatwaves and their predictability

a Power spectra of the Niño 3.4 indices of dynamic (blue) and slab (red) ocean simulations as well as their 95% confidence limits (dashed/dotted curves). Sea surface temperature standard deviations (color shading in °C) for (b) dynamic and (c) slab oceans, and (d) the difference between the two (dynamic minus slab). Scatterplots of monthly sea surface temperature versus monthly precipitation in the Niño 3 region for (e) dynamic and (f) slab oceans. Orange dots represent the cases when precipitation is larger than 5 mm/day. The black vertical and horizontal dashed lines denote the climatological mean values of sea surface temperature and precipitation, respectively. The base map is from NCAR Command Language map outline databases.
