Fig. 2

December to February (DJF) mean seasonal anomalies of air temperature (T; green) and zonal wind (U; brown) averaged over Maritime Continent (MC; 100°E−150°E, 15°S−5°N) composited for (a) westerly QBO (WQBO), (b) easterly QBO (EQBO), and (c) QBO-neutral states during Non-El Niño winters. Panel (d) shows the 41-year climatological DJF mean of T and U profiles (1981–2021). The think lines indicate the averages of the selected years (listed in Table 1).
