Fig. 4: DJF tropical Pacific response.
a–c U surface wind component [m/s]; d–f Latent heat flux (positive upwards) [W/m2]; g–i Outgoing Longwave Radiation (OLR) [W/m2]. Stippled areas indicate the anomalies significant at the 90% confidence level. (Note that the background easterly flow is negative, meaning that the negative anomalies are strengthening the easterly flow).
