A 1/8 Degree Model of the North Pacific Ocean

Abstract

Results from a 1/8 degree Pacific Ocean model (.125 degree, .176 degree resolution lat, long for each variable) are compared with results from several versions of a model with 1/4 degree resolution. All of the models are layered primitive equation, cover the Pacific Ocean north of 20S, include marginal seas, and have a free surface. The 1/8 degree model has 2 layers and realistic topography. The versions of the 1/4 degree model are 1.5 and 3.5 layer reduced gravity and 2-layer finite depth with realistic topography or a flat bottom. These models are used to show (1) the effects of horizontal resolution and vertical structure on flow instabilities and (2) the relative importance of time-varying wind and flow instabilities in producing a time dependent oceanic response.
