Central Eq. Pacific Heat Storage (surface to 300M)
and
Nino 3.4 Sea Surface Temperature (in Percentiles)
Click for options and more information
Heat Storage Based on:   Monthly ocean temperature on a 1.0 x 1.5 deg. lat/lon grid with vertical gridpoints at 5, 15, 25, 35, 45, 55, 65, 75, 85, 95, 105, 120. 135, 155, 175, 205, 240, 285, and 345 m.  (Jan 1980-present)
Nino 3.4 Sea Surface Temperature Data:  Monthly seas surface temperature on a 1.0 x 1.0 deg. lat/lon grid (Nov 1981-present)
Base Period (for both datasets above):  1982-present
Data Source:  NCEP, Environmental Monitoring Center, Climate Modeling Branch

Description:   The blue line indicates the ocean heat storage from the surface to 300 m depth averaged over the area 150-170W, 10S-10N in the central expressed as a percentile (from 0 to 1).  The black line indicates the Nino 3.4 region (120-170W, 5S-5N) average sea surface temperature again expressed as a percentile.  (NOTE:  The 0th percentile indicates the lowest value over the base period; the 100th percentile indicates the highest.  NCEP is an acronym for the US National Centers for Environmental Prediction.
