Central Equatorial Pacific Heat Storage and Niño 3.4 SST

This figure displays time series plots of percentiles of oceanic heat storage seasonal anomalies in the top 300 meters of the central equatorial Pacific Ocean, and percentiles of Niño 3.4 SST monthly anomalies from 1982 to the present.

The blue line is a time series of the percentile (expressed as a value between 0 and 1) of the seasonal (three-month) anomaly of GODAS oceanic potential temperature averaged from 10°S to 10°N latitude, and from 150°W to 170°W, and integrated from the surface to a depth of 300 meters. The black line is a time series of the percentile of monthly OIv2 SST anomalies averaged from 5°S to 5°N, and from 170°W to 120°W across the Niño 3.4 region in the equatorial Pacific. In both series, anomalies are calculated with respect to the 1982 to present base period. The 0th percentile (shown as 0 on the vertical axis) represents the lowest value over the base period, and the 100th percentile (shown as 1 on the vertical axis) represents the highest value over the base period.
