A coordinated set of Arctic modelling experiments, which explore how the Arctic responds to changes in external forcing, is proposed. Our goal is to compute and compare “climate response functions” (CRFs) – the transient response of key observable indicators such as sea-ice extent, freshwater content of the Beaufort Gyre, etc. – to abrupt “step” changes in forcing fields across a number of Arct...

As a semienclosed marginal sea, the Red Sea connects with open ocean through narrow strait at its southern end, known as Bab-al-Mandeb (BAM) strait. The water exchange between and Gulf of Aden BAM is crucial for mass transformations thermohaline circulation in well nutrient supply to ocean. In this study, three-dimensional high-resolution nonhydrostatic MIT general model (MITgcm) was used inves...

Air-sea exchange of gaseous elemental mercury (Hg(0)) is influenced by different meteorological factors and the availability Hg in seawater. Here, we use MITgcm ocean model to explore interannual variability this flux influence oceanographic atmospheric dynamics. We apply GEOS-Chem further simulate potential impact evasion on levels. find a latitudinal pattern Hg(0) with relatively small mid-la...

We present results of three simulations the Mediterranean Sea climate: a hindcast, historical run, and RCP8.5 scenario simulation reaching year 2100. The are performed with MED16, new, tide-including implementation MITgcm model, which covers Mediterranean—Black system resolution 1/16°, further increased at Gibraltar Turkish Straits. Validation hindcast against observations numerical reanalyses ...

Abstract. The Arctic regional coupled sea-ice–ocean–atmosphere model (ArcIOAM) has been developed to provide reliable sea ice prediction on seasonal timescales. description and implementation of ArcIOAM its preliminary results for the year 2012 are presented in this paper. In configuration, Community Coupler 2 (C-Coupler2) is used couple sea-ice–oceanic configuration MITgcm (Massachusetts Insti...

The atmospheres of ultra-hot Jupiters have been characterized in detail through recent phase curve and low- high-resolution emission transmission spectroscopic observations. Previous numerical studies analyzed the effect localized recombination hydrogen on atmospheric dynamics heat transport Jupiters, finding that dissociation lead to a reduction day-to-night contrasts relative previous expecta...

Abstract For eddy-permitting climate models, only eddies smaller than the smallest resolvable scale need to be parameterized. Therefore, it is important study diffusivities induced by a specific separation L * , that is, scale-dependent eddy diffusivities. Using submesoscale-permitting model solution (MITgcm llc4320), we estimate diffusivity in Kuroshio Extension. We find that, as increases, an...

Simulations with a 3D general circulation model (GCM) suggest that one potential driver behind the observed radius inflation in hot Jupiters may be downward advection of energy from highly irradiated photosphere into deeper layers. Here, we compare dynamical heat transport within non-inflated Jupiter WASP-43b and canonical inflated HD 209458b, similar effective temperatures. We investigate to w...

Abstract. The role of icebergs in narrow fjords hosting marine-terminating glaciers Greenland is poorly understood, even though iceberg melt results a substantial freshwater flux that can exceed the subglacial discharge. Furthermore, melting deep-keeled modifies vertical stratification fjord and, as such, impact ice–ocean exchanges at glacier front. We model an idealised representation high-sil...

Abstract. In this study, a new regional Earth system model is developed and applied to the Med-CORDEX (Coordinated Regional Climate Downscaling Experiment) region. The ENEA-REG made up of two interchangeable climate models as atmospheric components (RegCM, REGional Model, WRF, Weather Research Forecasting), river (Hydrological Discharge, HD), an ocean (Massachusetts Institute Technology General...
