Fig. 4: Effect of SST DA on SSTA and ZWA during ENSO events.

From: Key to ENSO phase-locking simulation: effects of sea surface temperature diurnal amplitude

Fig. 4

a, b Differences in SSTAs (blue to red coloring) and ZWAs (arrows) between Exp_large_DA and Exp_small_DA experiments during El Niño (a) and La Niña (b) in the FIO-ESM v2.0 model. c, d Similar to (a, b), but for differences in DAAs. The values are averaged between 5°S and 5°N. The green squares represent the Niño 3.4 region.
