metadata.name: dc.description.abstract
metadata.value: In this work, density inversions in the Greenland Sea, which precede a development of deep
  convection, were identified from in situ data. The mechanisms of their formation were considered,
  for which data from the GLORYS12V1 ocean reanalysis and the ERA5 atmospheric reanalysis
  were used. In particular, the jet intrusions of warm Atlantic Water and cold water from
  the East Greenland Current was identified, the role of ocean-atmosphere heat flux and the
  freshwater balance of the sea surface were determined over two time periods: the 1990s (1993,
  1994, 1998) and the 2010s (2008, 2011, 2013). The following main mechanisms of formation
  of the density inversions were identified: The ocean-atmosphere heat flux, jet intrusions of the
  upper ocean water, and difference between evaporation and precipitation. The density inversions
  are often formed by a combination of these mechanisms. The ocean-atmosphere heat
  flux is the main source of inversions observed with 93 % of the profiles with inversions. In the
  1990s, jet intrusions of ocean water formed the second most important factor, with the difference
  evaporation-precipitation being the third one. In the 2010s, however, the third factor
  became more important than the second one, as evaporation started dominating significantly
  over precipitation. An increase of a contribution of the latter factor occured together with an
  increase in the number of salinity inversions during the 2010s compared to the 1990s and was
  a result of a change in the dominating winds over the region. These results form a basis for
  further investigation of the mechanisms of interannual variability of deep convection in the
  Greenland Sea.
