FigS1.pdfPDF document31KMulti-variable EOF of 850-hPa winds, sea level pressure (contour lines) and land precipitation (shading) for the period 1979-2004. (a) and (b) are the spatial pattern from ECHAM5 simulations and observational data, respectively. (c) shows the principle component for ECHAM 5 (black solid-open circle line) and observation (red solid-open circle line). The similar spatial patterns and the correlation value (0.64) between the two component indicate the ECHAM 5 performance in simulating EASM.
newFigS2.epsPS document579KAtmospheric anomalies as responses to cold SST anomalies over a patch (blue shading in (a)) in the central Pacific. The sea level pressure (contours in (a)), 850-hPa winds (vectors in (a)), 200-hPa geopotential high (contours in (b)), 200-hPa winds, and precipitation (shading in (b), in unit mm/day) are shown. The contour interval is 0.3 hPa in (a) and 5 geopotential meters in (b). Negative contours are denoted with blue dash while others are denoted with red solid.
FigS3.pdfPDF document1125KPositive-negative composite analysis of SSTA (shading), 850-hPa wind anomalies (vectors), and SLP anomalies (contour lines with yellow for positive, green for negative and zero lines omitted) in spring (MAM, left column) and summer (JJA, middle column) for the cases of (the 1st row) all the El Niño decays phases, (the 2nd row) El Niño decays only to neutral conditions, (the 3rd row) all the La Niña developing phases, and (the 4th row) La Niña develops only from neutral conditions. For reference, the evolution of Niño-3.4 SSTAs for each year is shown in the right column (c, f, i, and l) with the red lines for the same sign as the case defined, and the blue lines for the sign-reversed opposite ENSO phase. For instance, the red in (c) indicates that of El Niño decay while the blue indicates the sign-reversed that of La Niña decay.
