warm subsurface ocean temperatures (e.g., Lin et al. 2009 ; Jaimes and Shay 2009 , 2015 ; Yablonsky and Ginis 2013 ; Girishkumar and Ravichandran 2012 ; Lin et al. 2014 ; Balaguru et al. 2018 ). Some recent studies address the interaction between tropical cyclones and the ocean in the presence of a “barrier layer,” that is, a deep, warm isothermal layer lying beneath a shallow, salinity-stratified layer ( Sengupta et al. 2008 ; Balaguru et al. 2012 , 2014 ; Neetu et al. 2012 ; Vincent et

and potentially forecasted TC intensity. To address the gaps from previous literature, several one-dimensional (1D) mixed layer model experiments are analyzed to investigate how the inclusion of salinity in different thermal regimes impacts the SST response. BL erosion time is estimated to assess the resilience of the upper-ocean thermal and haline structure to each mixing scheme. The use of several mixing schemes highlights how individual upper-ocean processes, such as shear-induced mixing and

1. Introduction It has been a century since the demonstration of the relation of ocean currents to density gradients ( Helland-Hansen and Nansen 1909 ). The data from the Meteor expedition ( Wüst 1935 ) showed the close alignment of core layers in the ocean, on which water properties like salinity, dissolved oxygen, etc., assumed extremal values, with strata of density corrected, however crudely, for adiabatic compression. [Usually, σ t was used, which is merely the in situ density with its

1. Introduction The fate of the thermohaline circulation is a major issue for climate change and the observation of its large-scale components, mass, heat, and freshwater transports, has progressed at a fast pace following the World Ocean Circulation Experiment (WOCE). As deep water is produced continuously and as the interior properties of the ocean hardly change over a century of temperature–salinity observations, Munk (1966) and Munk and Wunsch (1998) conclude that the deep water has to

is about 0.6 m s −1 in the middle of estuary (half of the salt intrusion). A weak coastal current (∼0.05 m s −1 ) is specified on the shelf to transport the river plume. Temperature is fixed at 15°C throughout the domain. Salinity at the river end is set to 0, whereas at the shelf boundaries salinity is nudged to an oceanic value of 32. The k − ε turbulence closure ( Jones and Launder 1972 ) is activated with the stability function proposed by Canuto et al. (2001) . The k − ε closure has

ocean general circulation model (OGCM) to different surface heat and freshwaterfluxes is examined. The aim is to determine the most appropriate way to spin up an OGCM prior to couplingit with an atmospheric GCM. Attention is focused on surface boundary conditions for salinity since otherstudies suggest that so-called "mixed" boundary conditions (i.e., a restoring condition on sea surface temperatureand flux condition on sea surface salinity) can yield multiple equilibrium states in ocean models
