ROMS configuration of a two-way nested model of the Mid-Atlantic Bight and Delaware Bay.

This is an archive of model configuration files for the Regional Ocean Modeling System (ROMS) with two grids and two-way nesting. The parent grid resolution (referred to as Doppio) is 7 km and spans the Atlantic Ocean off the northeast United States from Cape Hatteras to Nova Scotia. The refinement grid (referred to as Snaildel) focuses on Delaware Bay and the adjacent coastal ocean at 1 km resolution. This ROMS configuration uses turbulence kinetic energy flux and significant wave height from Simulating Waves Nearshore (SWAN) as surface boundary conditions for turbulence closure.

Also included is a MATLAB script to compute statistics of acceleration and vorticity caused by turbulence.

This model configuration is part of NSF-funded research investigating the link between behavior and transport of larvae using waves and turbulence as cues. It provides the 4-dimensional velocity field used in the offline particle tracking model ROMSPath, as well as 4-D temperature and turbulent quantities necessary to simulate larvae behavior.
