Studies Of Warm-Core Rings Using A Particle-In-Cell Method, John James Holdzkom Ii
Studies Of Warm-Core Rings Using A Particle-In-Cell Method, John James Holdzkom Ii
OES Theses and Dissertations
A particle-in-cell (PIC) model is developed and applied to problems involving the evolution of warm-core rings. Such models are a hybrid of conventional Eulerian and Lagrangian models. They are ideally suited for problems in which a lower layer outcrops to the surface, such as at the boundary of a ring.
The model is developed in three implementations. First, for purposes of model validation, a reduced gravity model is described. The PIC model reproduces the essential characteristics 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 …
Numerical Model Simulation Of Offshore Flow During The Winter Season, Maria Cintia Piccolo
Numerical Model Simulation Of Offshore Flow During The Winter Season, Maria Cintia Piccolo
OES Theses and Dissertations
Because of the step function variability of heat and moisture flux in coastal zones, adequate descriptive models of mesoscale coastal circulation and weather patterns demand high spatial resolution in the analysis of wind, temperature and moisture patterns. To obtain realistic concepts of offshore flow the sparse offshore data networks need to be supplemented by mesoscale numerical models. The problems associated with the modeling of offshore flow across the east coast of the United States during the winter season have been investigated with a simple two dimensional numerical model of the planetary boundary layer.
The model has two predictive equations for …
