In 2023, the sea surface temperature (SST) and upper 2000 m ocean heat content (OHC) reached record highs. The 0–2000 m OHC in 2023 exceeded that of 2022 by 15 ± 10 ZJ (1 Zetta Joules = 1021Joules) (updated IAP/CAS data); 9 ± 5 ZJ (NCEI/NOAA data). The Tropical Atlantic ...
The world’s oceans are under threat from the prevalence of heatwaves caused by climate change. Despite this, there is a lack of understanding regarding their impact on seawater oxygen levels - a crucial element in sustaining biological survival. Here, we find that heatwaves can trigger low-oxy...
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 ...
The Southern Ocean provides dominant contributions to global ocean heat and carbon uptake, which is widely interpreted as resulting from its unique upwelling and circulation. Here we show a large asymmetry in these contributions, with the Southern Ocean
Shifts in the central latitude of the Gulf Stream extension have also been linked to heat content and coastal sea level variability (Dong et al., 2019; Ezer, 2019; Todd & Ren, 2023), with this position more directly related to basin-scale wind and buoyancy forcing associated with the NAO...
This CDR quantifies ocean heat content change over time, which is an essential metric for understanding climate change and the Earth's energy budget. It provides time-series for multiple depth ranges in the global ocean and each of the major basins (Atlantic, Pacific, and Indian) divided by...
【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 …
Ocean heat content anomaly (OHCa) time series in some areas of the Pacific are significantly correlated with the total solar irradiance (TSI). Using the composite mean-difference method, we determined the mean response of OHCa in the upper-700 m of the ocean to the TSI. Among the high sola...
Ocean heat content at a record high So far, 2018 has set a new record for the total amount of warmth stored in the seas – known as ocean heat content (OHC). Measured OHC was warmer than any other year since observations began in the early 1940s. ...
Upper ocean heat content (UOHC) was used as a thermodynamic variable to represent oceanic heat energy changes46. Negative (positive) UOHC anomalies were considered to represent heat loss or cooling (gain or warming) in the upper ocean after the passage of a TC. Among the eleven events ...
