GOAL OF THIS WORK
■ To investigate larval transport in “idealized” simulations
● To describe long term & short term dispersal kernels
● Four scenarios considered
▷ Strong or weak upwelling
▷ Northern or southern California
■ To develop modeling to establish short time kernels
from available data sets
IDEALIZED SIMULATIONS
■ Idealized is state that shows
1) statistical stationarity
2) statistical homogeneity in alongshore
3) physically reasonable coastal current
■ Make particle tracking easier
■ No such simulation in literature
● Need to construct our own
OBJECTIVE OF THIS TALK
■ To show progress in simulation construction
● Focus on summer northern California
● Hard to satisfy three “idealized” conditions
● Still some problems in simulations
ROADMAP
■ Four things to be modeled
1) Numerical domain
2) Boundary conditions
3) Initial conditions
4) Forcings
■ Show obtained simulation fields & trajectories
■ Research plan to obtain kernel
1) NUMERICAL DOMAIN
■ 64 x 64 x 32 grid points
512 km x 512 km Depth: 20 m -- 500 m
2) BOUNDARY CONDITIONS
Periodic
Periodic
Free-slip wall
Nudging &sponge layer
Wind stressOpen B.C.'s
2) BOUNDARY CONDITIONS
■ Open B.C.'s
● Outflow: radiation
▷ Extrapolates boundary values from interior values
