The Indo-Pacific Warm Pool (IPWP) exerts a dominant role in global climate by releasing huge amounts of water vapour and latent heat to the atmosphere and modulating upper ocean heat content (OHC), which has been implicated in modern climate change1. The long-term variations of IPWP OHC ...
Ocean warming is often measured by tracking changes in ocean heat content (OHC). A useful coordinate to analyze OHC changes is a density- or temperature-based framework because this is a more natural coordinate to explore the thermodynamics of ocean warming21,22,23. Deepening of isopycnals is ...
The land-ocean ratio is responsible for the geographical distribution of the annual cycle of ocean heat content. Globally, the amplitude of annual harmonic of upper ocean heat content is 3.7 × 10J for the World Ocean, 10.2 × 10J for the Southern Hemisphere, and 6.5 × 10J for the ...
Accurate knowledge of the location and magnitude of ocean heat content (OHC) variability and change is essential for understanding the processes that govern decadal variations in surface temperature, quantifying changes in the planetary energy budget, and developing constraints on the transient climate res...
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...
【数据分享】海洋热含量Global Ocean Heat Content CDR 海洋热含量数据可以不用计算了,直接下载使用! 海洋热含量气候数据记录(CDR)是一组 1955 年至今的海洋热含量异常(OHCA)时间序列,以 3 个月、1 年和 5 年为尺度。该 CDR 量化了海洋热含量随时间的变化,是了解气候变化和地球能量预算的重要指标。它提供了按...
Ocean heat content (OHC) change contributes substantially to global sea level rise, so it is a vital task for the climate research community to estimate historical OHC. While there are large uncertainties regarding its value, in this study, the authors discuss recent progress to reduce the errors...
A new assessment of how much heat Earth has accumulated since 1960 is made by examining ocean heat content changes. Earth's energy imbalance (EEI) drives the ongoing global warming and can best be assessed across the historical record (that is, since 1960) from ocean heat content (OHC) chan...
Drivers of ocean heat content variability To examine the role of the ocean further, it is necessary to move beyond SST and consider the heat budget of the mixed layer in the upper ocean which, by definition, has close to the same temperature as the surface26. We determine the change (∆...
The model run with these settings except that the sea surface heat flux was set to be zero was also conducted for evaluating the importance of air–sea heat exchange in the upper ocean response to extreme strong typhoon wind. Calculation of velocity shear and buoyancy frequency The velocity ...
