Just a snippet, get the rest here: http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso_advisory/ensodisc.pdf El Niño strengthened from October to November 2009, as sea surface temperature (SST) anomalies increased across the central and eastern equatorial Pacific Ocean (Figs. 1 and 2). The Niño-3.4 index value remained steady during November with the most recent weekly value at +1.7°C (Fig. 2). Consistent with this warmth, upper-ocean heat content anomalies remained positive (Fig. 3) and subsurface temperature anomalies shifted eastward across the eastern Pacific, with the largest departures exceeding +4°C by the end of the month (Fig. 4). Also, the low-level and upper-level wind anomalies over the equatorial Pacific were highly variable during the month due to the Madden-Julian Oscillation (MJO). The MJO also contributed to anomalous convection over Indonesia and the west-central equatorial Pacific (110°E to 180°; Fig. 5). Collectively, these oceanic and atmospheric anomalies reflect a moderate strength El Niño. All I want to know if this is going to give us waves or take them away.
