The structure of zonal wind anomalies associated with El Niño. a The correlation between boreal winter Nino3.4 SST index and monthly equatorial (averaged over 5°S to 5°N) zonal wind anomalies. Panels b and c are the same, but here the Nino3.4 index was correlated with wind anomalies during August and December, respectively. Monthly data from 1958 to 2015 were used in the calculation. These were pre-processed by removing decadal anomalies with periods longer than 7 years. Then, a 5-month running mean was used to smooth the data of high-frequency variations. Data during all months of 1972, 1982, and 1997 were excluded from the analysis. The maps in the figure were rendered with the NCAR Command Language software (https://doi.org/10.5065/D6WD3XH5) from the Global Self-consistent, Hierarchical, High-resolution Geography Database (GSHHG).
