data from the NCEP Climate Forecast System version 2 (CFSv2; Saha et al. 2011 ), and uses 3-hourly HYCOM boundary conditions ( Chassignet et al. 2007 ) with tides from the Oregon State University Tidal Prediction Software (OTPS; Egbert and Erofeeva 2002 ) (30-min resolution). For further details of the setup and the validation of the model, we refer to Lorenz et al. (2020) . The Persian Gulf is a semi-enclosed marginal sea with net freshwater loss due to evaporation. Its exchange flow is

1. Introduction As a rule, surface circulation in Northern Hemisphere lakes and marginal seas is cyclonic or counterclockwise ( Shtokman 1967 ; Emery and Csanady 1973 ). The pattern is observed in a number of North American and Eurasian lakes as well as in various inland seas: the Adriatic Sea, Baltic Sea, Bay of Fundy, Black Sea, Gulf of St. Lawrence, Japan Sea, Mediterranean Sea, Persian Gulf, etc. The only exception to the rule appears to be the Aral Sea in which the circulation of surface

1. Introduction The Bay of Campeche (BOC) is the southwestern part of the Gulf of Mexico (GM), where the isobaths follow approximately a U shape with a smooth slope on the western side and a rough slope to the east ( Fig. 1 ). The BOC ends in the west with a narrow shelf near the coast, its central and northern parts are connected with deep GM waters, and its south and east limits are characterized by shallow ample shelves less than 50 m deep. In this study, an unprecedented set of deep current

least one neutrally stable, stationary long wave exists, but the other waves may have imaginary speeds. 3. Numerical model description The numerical model used for this study is the three-dimensional σ -coordinate Princeton Ocean Model (POM) designed in the late 1970s by Blumberg and Mellor (1987) to study both coastal and open ocean circulation. The model uses a curvilinear orthogonal grid covering the region between the Gulf of Cadiz and the Alboran Sea ( Fig. 6 ). The grid has a nonuniform

there. We also provide an overview of the current, wind, and sea level fluctuations observed during the winter deployment, which is the focus of this analysis. In section 3 , we discuss the subinertial variability, from pressure fluctuations to current and drifter observations. We examine the extent to which wind forcing can explain the observed variability. The wind-driven response is isolated and compared with idealized linear models. These models reproduce the cross-bay circulation but fail to

1. Introduction September ice extent in the Arctic has declined by approximately 10% decade −1 between 1979 and 2007 (e.g., Comiso et al. 2008 ). This dramatic loss of ice has fueled interest in the seasonal predictability of sea ice, both regionally and Arctic wide, as a means to isolate the main internal and external climate forcings. Regionally, with the exception of the Bering Sea, the greatest reductions have occurred in Hudson Bay ( Parkinson and Cavalieri 2008 ). Over the same period

in the western and southern Gulf of Mexico sustain this claim ( Tenreiro et al. 2018 ). Along the continental slope, current meter moorings and subsurface floats have confirmed the existence of a mean westward flow over the northern slope (e.g., Donohue et al. 2006 ; Hamilton 2009 ). The mooring observations of Tenreiro et al. (2018) also show mean flow along the western boundary, although it is less clear if this flow continues into the Bay of Campeche (BOC). Hence, the presence, continuity

the oceanic response N O . It also varies from one variable to another (e.g., flow, sea level). For example, at the mouth of Delaware Bay Garvine (1985) and Janzen and Wong (2002) showed that depth-averaged flow and sea level are produced predominantly by the propagation of the oceanic response inside the bay, but pressure gradients and three-dimensional currents are produced primarily by the local wind. Estimating the importance of closed-basin and secondary contributions requires inspection

–Faeroe Ridge were attributable to a resonant barotropic topographic Rossby normal mode trapped on the ridge. A barotropic shallow water model by Pierini (1996) suggested the excitation of topographic Rossby modes (TRMs) in the Strait of Sicily of the central Mediterranean Sea, which were dominated by 2–5-day period variations. Furthermore, Hamilton (2007) suggested that locally trapped short-period TRWs (<10 day) in the Gulf of Mexico were associated with the reflection and refraction of longer
