Stochastic Ocean Forecasting with the Dynamically Orthogonal Primitive Equations
… focuses on applying the Dynamically Orthogonal Primitive Equations (DO-PE) for realistic high-resolution stochastic ocean forecasting in regions with complex ocean dynamics. In the first part, we identify and test a streamlined process to create multi-region initial conditions for the DO-PE …

Well-posedness and blowup results for the swirl-free and axisymmetric primitive equations in a cylinder
… for the Cauchy problem for the inviscid primitive equations, also called the hydrostatic incompressible Euler equations, on a cylinder, under some extra conditions. Following the method introduced by Kukavica-Temam-Vicol-Ziane in Int. J. Differ. Equ. 250 (2011) , we use the suitable …

Modeling Mesoscale Eddies: the Effects of Resolution onOcean Turbulence
… required to represent mesoscale eddies in the primitive equations. Convergence is evaluated through several metrics, including surface and depth-integrated kinetic energy, spectra, and zonally-averaged temperature, in order to establish quantitative resolution thresholds for physical fidelity. …

Representation of eddies in climate models by a potential vorticity flux
… of eddy motions for use in three-dimensional, primitive equation, z-coordinate atmosphere and ocean models. Determining the transport characteristics of these eddies is fundamental to understanding their effect on the large-scale ocean circulation and global climate. The approach is to …

Warm and cold atmospheric frontogenesis
… modeled. The hydrostatic, adiabatic, Boussinesq primitive equations are integrated on a two dimensional grid. The frontogenesis is forced by an a1ong·front gradient of potential temperature and by a vertically sheared cross-front wind field. The model develops fronts with the proper vertical …

Middle latitude forcing of a model tropical atmosphere with horizontally nonuniform basic states
A model of the tropical atmosphere, based on the primitive equations with beta-plane geometry and a latitudinally and longitudinally varying basic state is used to simulate the response of the tropics to middle latitude forcing. The equations of motion are linearized about a seasonally dependent …

Studies of Warm-Core Rings Using a Particle-in-Cell Method
… of analytical solutions to the reduced gravity equations and integral invariants are conserved to a high degree. Next, a 1.5-layer model is developed and used to study the effects of environmental forcing on the evolution of warm-core rings. This model incorporates forcing by a prescribed …

Probabilistic regional ocean predictions : stochastic fields and optimal planning
… and even the model parameterizations and equations themselves. To reduce uncertainties and allow long-duration measurements, the energy consumption of ocean observing platforms need to be optimized. Predicting the distributions of reachable regions, time-optimal paths, and risk-optimal …

Studies of gravity wave and thermal tide and their interactions in the middle atmosphere
… theory and the calculations based on the full primitive equations. In the WACCM, GW forcing in the wave breaking region always damps DW1 and advances its phase, thus shortening the vertical wavelength of the tide locally. The linear advection largely determined by the latitudinal shear of the …

Dynamical Reduced-Order Models for High-Dimensional Systems
… from either a simplification of the original equations, a set of known functions such as orthogonal polynomials, or a reduced basis of full-order simulations computed offline. However, if the true system exits the span of the prescribed subspace, such approaches quickly accumulate large …
