Western Pacific interannual variability associated with the El Niño‐Southern Oscillation

Interannual SST variability in the Japan/East Sea and relationship with environmental variables

“…In the first mode the LCC of NPI (or AOI) is out of phase to that of WPI (or MEI) as a correlation between CIs (not shown). This supports the hypothesis that the cold anomaly of the northwestern Pacific SST is related to the negative phase of AOI, low SLP in the midlatitude, and warm ENSO event (Thompson and Wallace, 1998;Wang et al, 1999). The first mode SSTA is positively correlated to NPI and AOI and negatively (weakly) correlated to WPI and MEI at zero lag.…”

Coherent Tropical Indo-Pacific Interannual Climate Variability

“…Figure 10a shows that in July of year 0, the main part of the IO is significantly cooler than normal, with the largest deviation of 0.8 K in the SD region. In the equatorial PO, remnants of a previous La Niña can be seen, surrounded by warmer anomalies (horseshoe pattern; Wang et al 1999), especially in the southwestern PO under the South Pacific convergence zone. From March to October, the wind to the west of Indonesia is westerly, while to the east of Indonesia, above the western PO, it is easterly (Fig.…”

Why 1986 El Niño and 2005 La Niña evolved different from a typical El Niño and La Niña

“…But such a wind field pattern changed in the following mature winter. For the typical EN, there is an anomalous WNPAC occurred (Wang et al 1999(Wang et al , 2003Weisberg and Wang 1997), and to south of WNPAC, it is dominated by anomalous easterly wind along the equatorial WP (Wu et al 2010;Fig. 2e).…”
