Fig. 1: Model performance in simulating Indo-Pacific climate modes.

From: Unraveling the interactions between tropical Indo-Pacific climate modes using a simple model framework

Fig. 1

Seasonal variations in the standard deviation of the (a) Niño3.4 (\({T}_{p})\), b tropical Pacific thermocline depth anomalies (\({h}_{p})\), c IOB-M, and d DMI from observations (black line) and model simulations (red line). The red shading represents the one-standard deviation inter-ensemble spread. e–h Show the power spectra of each index. The gray lines in (c) and (g) represent the seasonal variations and power spectrum of the traditional IOB index, respectively. To enable a fair comparison of the power spectra between the actual and control experiment, 100 random segments of the control time series, each matching the length of the observed index, were extracted and averaged.
