Abstract: The generalized inverse is constructed for a nonlinear, single-layer quasigeostrophic model, together with initial conditions and a finite number of interior data. With the exception of doubly Periodic boundary condition ...

Abstract: When averaging the equations of motion, thermodynamics, and scalar conservation over turbulent fluctuations, we perform the process in several stages. First, an average is taken over the microscopic scales of turbulence, ...

Abstract: The ill-posedness of regional primitive equation models is examined, using a regional shallow-water model. The ill-posedness is resolved by reformulation as a least-squares inverse problem, in the sense that the Euler-Lagrange ...

Abstract: An analysis of variational data assimilation schemes for linear dynamical forecast models shows that the penalty functional must include an explicit contribution from the initial conditions in order to ensure a unique, ...

Abstract: A parallel algorithm is described for variational assimilation of observations into oceanic and atmospheric models. The algorithm may be coded first for execution on a serial computer and then trivially modified for execution ...

Abstract: Numerical simulations of two-dimensional turbulence show that O(??1) and O(??4) energy spectra?described by Fox and Orszag (1973a) as enstrophy-equipartitioning and strongly dissipating turbulence, respectively?occur ...

Abstract: Meridional eddy heat flux in the subtropical North Pacific is estimated from TRANSPAC ship-of-opportunity data collected during 1976?80. Two methods are used. The first fits simple functional forms to be temporal anomalies ...

Abstract: Practical hydrostatic ocean models are often restricted to statically stable configurations by the use of a convective adjustment. A common way to do this is to assign an infinite boat conductivity to the water at a given ...

Abstract: A nonlinear 2½-layer reduced gravity primitive equations (PE) ocean model is used to assimilate sea surface temperature (SST) data from the Tropical Atmosphere?Ocean (TAO) moored buoys in the tropical Pacific. The aim of ...

Abstract: The investigation of the consequences of trying to blend tropical Pacific observations from the Tropical Atmosphere?Ocean (TAO) array into the dynamical framework of an intermediate coupled ocean?atmosphere model is ...
