Fig. 4: Seasonal evolution of atmospheric patterns in association with IOD and ENSO.

From: Indian Ocean Dipole and ENSO’s mechanistic importance in modulating the ensuing-summer precipitation over Eastern China

Fig. 4

Composite seasonal evolution of horizontal winds (vectors) at 850 hPa and sea surface pressure (shading, Pa) from autumn to the ensuing summer based on the years when a–d only IOD occurs, e–h only El Niño occurs, and i–l IOD and ENSO occur together. Vectors indicate winds that exceed the 95% confidence level. Thick black contours denote sea surface pressure exceeding the 95% confidence level.
