DOI: 10.1002/2017ms000951
Abstract: Satellite observations of the magnetic field induced by the general ocean circulation could provide new constraints on global oceanic water and heat transports. This opportunity is investigated in a model-based twin experiment by assimilating synthetic… read more here.

DOI: 10.1007/s00376-021-1167-y
Abstract: State-of-the-art coupled general circulation models (CGCMs) are used to predict ocean heat uptake (OHU) and sea-level change under global warming. However, the projections of different models vary, resulting in high uncertainty. Much of the inter-model… read more here.

DOI: 10.1007/s00382-020-05616-5
Abstract: The current generation of coupled ocean–atmosphere climate models, which are widely used for studying the dynamics of the climate system and to make projections of future climate, suffers from erroneously warm (exceeding 5 °C) sea… read more here.

DOI: 10.1007/s10236-019-01268-0
Abstract: In this study, we investigate how sea ice extent and thickness are affected by additional turbulent mixing from unbroken surface waves. This ‘surface wave mixing’ (SWM) is parameterized by the inclusion of an extra mixing… read more here.

DOI: 10.1007/s11430-016-0201-9
Abstract: The tropical Pacific experienced a sustained warm sea surface condition that started in 2014 and a very strong El Niño event in 2015. One striking feature of this event was the horseshoe-like pattern of positive… read more here.

Abstract: Abstract We identify Lagrangian coherent vortices in a global mesoscale eddy-permitting ocean model using the rotation-based method of Haller et al. (2016). We present an analysis of the acute sensitivity of the identification results to varying… read more here.

DOI: 10.1016/j.ocemod.2018.09.003
Abstract: It is expected that the assimilation of data in an ocean model disrupts the model’s dynamical balance. This disruption occurs because the analysis fields are not a precise solution to the equations of the model.… read more here.
