| In a changing climate, a description of the permanent pycnocline, which is globally coherent and independant from any thermohaline properties, is required in order to provide a reference state for the identification of the warm water sphere variability. Using a recently developped pattern recognition method applied to stratification profiles from Argo in situ data, this study presents such a reference state for the subtropical latitudes and the 2000-2015 period. With this method, a mode water core is recognised as a stratification minimum that is, possibly temporarely, trapped below the seasonal pycnocline. The permanent pycnocline is recognised as the stratification maximum localised below that mode water core. First, we will show that away from... |
