Northwest Pacific subtropical countercurrent on isopycnal surface in summer
[1] A three-dimensional absolute velocity field on the isopycnal surface in the northwest Pacific subtropical region in the summer is calculated from the Navy’s Generalized Digital Environmental Model (GDEM) climatological temperature and salinity data on a 0.5 0.5 grid using the P-vector method. GDEM for the area was built from historical (1930–1997) temperature and salinity profiles. The basi...
متن کاملP-Vector Spirals and Determination of Absolute Velocities
A simple method to invert the absolute geostrophic velocity on potential-density surfaces is developed based on McDougall’s (1988) conservation statements on potential-density surfaces and Chu’s (1995) and McDougall’s (1995) P-vector concept. This method has a capability to handle a system with diapycnal velocities and non-coincidence of potential-density and neutral surfaces. The validity of t...
متن کاملP-Vector Inverse Method Evaluated Using the Modular Ocean Model (MOM)
Several major inverse methods (Stommel-Schott method, Wunsch method, and Bernoulli method) have been successfully developed to quantitatively estimate the geostrophic velocity at the reference level from hydrographic data. No matter the different appearance, they are based on the same dynamical sophistication: geostrophy, hydrostatic, and potential density (ρ) conservation (Davis, 1978). The cu...
متن کاملA method to obtain the mean transports of ocean currents by combining isopycnal float data with historical hydrography
This article presents a method to obtain the mean structure of temperature, specific volume anomaly, and velocity of an ocean current, using isopycnal float data combined with Gravest Empirical Mode (GEM) fields calculated from historical hydrography. A GEM field is a projection on geostrophic stream function space of hydrographic data, which captures most of the vertical structure associated w...
متن کاملIsopycnal Eddy Diffusivities and Critical Layers in the Kuroshio Extension from an Eddying Ocean Model
High spatial resolution isopycnal diffusivities are estimated in the Kuroshio Extension (KE) region (288– 408N, 1208–1908E) from a global 1/108 Parallel Ocean Program (POP) simulation. The numerical float tracks are binned using a clustering approach. The number of tracks in each bin is thus roughly the same leading to diffusivity estimates that converge better than those in bins defined by a r...
