Distinctive climate signals in reanalysis of global ocean heat content
[1] The elusive nature of the post-2004 upper ocean warming has exposed uncertainties in the ocean’s role in the Earth’s energy budget and transient climate sensitivity. Here we present the time evolution of the global ocean heat content for 1958 through 2009 from a new observationbased reanalysis of the ocean. Volcanic eruptions and El Niño events are identified as sharp cooling events punctua...
متن کاملGlobal upper ocean heat content and climate variability
Observational data from the Global Temperature and Salinity Profile Program were used to calculate the upper ocean heat content (OHC) anomaly. The thickness of the upper layer is taken as 300 m for the Pacific/Atlantic Ocean and 150 m for the Indian Ocean since the Indian Ocean has shallower thermoclines. First, the optimal spectral decomposition scheme was used to build up monthly synoptic tem...
متن کاملDecadal changes of ENSO persistence barrier in SST and ocean heat content indices: 1958–2001
[1] Decadal changes of El Niño-Southern Oscillation (ENSO) persistence barriers in various indices of sea surface temperature (SST) and ocean heat content (OHC) are examined in this study using observations and ocean data assimilation products for the period 1958–2001. It is found that the SST indices in the eastern and central equatorial Pacific exhibit very different decadal barrier variabili...
متن کاملSurface flux and ocean heat transport convergence contributions to seasonal and interannual variations of ocean heat content
We present an observation-based heat budget analysis for seasonal and interannual variations of ocean heat content (H) in the mixed layer (Hmld) and full-depth ocean (Htot). Surface heat flux and ocean heat content estimates are combined using a novel Kalman smoother-based method. Regional contributions from ocean heat transport convergences are inferred as a residual and the dominant drivers o...
