A long standing debate has wondered how and if the El Niño–Southern Oscillation (ENSO) and the quasi-biennial oscillation (QBO) are connected. Some studies suggest that ENSO might influence the timing and/or strength of the QBO, but clear evidence has been hard to find. Recently, surface climate patterns, especially sea surface temperatures, appear to show direct and convincing links between ENSO and the QBO. However, because the available data record is relatively short and noisy, it's unclear whether these patterns reflect a true physical connection or are just coincidental. To explore this, we use simplified models of both ENSO and the QBO to test whether such correlations could appear by chance in a short dataset. By comparing the model results with real-world observations, they aim to determine whether the observed relationships are due to an actual physical link or simply a statistical fluke.
