Global 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 کاملInterannual Variability in Upper-Ocean Heat Content, Temperature and Thermosteric Expansion on Global Scales
Satellite altimetric height was combined with approximately 1,000,000 in situ temperature profiles to produce global estimates of upper-ocean heat content, temperature and thermosteric sea-level variability on interannual time scales. Maps of these quantities from mid-1993 through mid-2003 were calculated using the technique developed by Willis et al. [2003]. The time series of globally average...
متن کاملSeasonal variability of upper ocean heat content in Drake Passage
[1] Mixed-layer depth (MLD) is often used in a mixed-layer heat budget to relate air-sea exchange to changes in the near-surface ocean temperature. In this study, reanalysis heat flux products and profiles from a 15 year time series of high-resolution, near-repeat expendable bathythermograph/expendable conductivity-temperature-depth (XBT/XCTD) sampling in Drake Passage are used to examine the n...
متن کاملSpatial and temporal variability of global ocean mixing inferred from Argo profiles
[1] The influence of turbulent ocean mixing transcends its inherently small scales to affect large scale ocean processes including water-mass transformation, stratification maintenance, and the overturning circulation. However, the distribution of ocean mixing is not well described by sparse ship-based observations since this mixing is both spatially patchy and temporally intermittent. We use s...
متن کاملUpper Ocean Heat and Freshwater Budgets
The surface layer of the ocean undergoes temperature variations which occur at several different temporal scales: a diurnal cycle reSecting day and night variability, an annual cycle showing seasonal variations in insolation and weather, and interannual to decadal cycles, indicating large-scale, long-term climate variability. The strength of a given cycle also depends on the location, for examp...
