“…The turbulent air/sea and air/ice fluxes are calculated by the bulk parameterization of Fairall et al (1996). The model uses Flather (1976) and Chapman (1985) boundary conditions for barotropic normal velocity components and the sea surface elevation along open boundaries. Temperature, salinity, and baroclinic velocity components at open boundaries are calculated with a radiation condition suggested by Marchesiello et al (2001).…”

Ever since the Arctic region has opened its mysterious passage to mankind, continuous attempts to take advantage of its fastest route across the region has been made. The Arctic region is still covered by thick ice and thus finding a feasible navigating route is essential for an economical voyage. To find the optimal route, it is necessary to establish an efficient transit model that enables us to simulate every possible route in advance. In this work, an enhanced algorithm to determine the optimal route in the Arctic region is introduced. A transit model based on the simulated sea ice and environmental data numerically modeled in the Arctic is developed. By integrating the simulated data into a transit model, further applications such as route simulation, cost estimation or hindcast can be easily performed. An in-teractive simulation system that determines the optimal Arctic route using the transit model is developed. The simulation of optimal routes is carried out and the validity of the results is discussed.

“…The open boundary condition for the barotropic component consists of the Chapman (Chapman 1985) formulation for surface elevation and the Flather (Flather 1976) formulation for velocity. For baroclinic component at the open boundary includes an Orlanski-type radiation condition (Marchesiello et al 2001).…”

In this study we examine offshore transport and dispersal pathways of the freshwater discharge from the Changjiang River in the East China Sea (ECS), using a regional ECS model. Comparison between the results for 1996 and 1998 clearly shows that the summer monsoon winds play a significant role in spreading the freshwater discharge offshore and determining the dispersal of freshwater in the ECS. Analysis of 10-year simulation demonstrates that a northeastward freshwater transport to Jeju Island across the northwestern shelf of the ECS dominates during the summer period due to the surface Ekman flow by the southeasterly along-shore wind. Meanwhile, there is virtually no relationship between the amount of the summer discharge and the freshwater pathway toward Jeju Island. Our analysis also suggests that when the summer wind is relatively weak, another freshwater pathway toward the central ECS appears with the ambient along-shelf current between the Taiwan Strait and the Korea Strait.

“…For free-surface models, such as this one, it is important that the boundary conditions be transparent to the waves. In this model, a zero gradient boundary condition (Chapman, 1985) is used for the elevation. This boundary condition assumes that the phase speed is infinite.…”
