ROMS-AGRIF
Full physics. Meteorological forcing by a high resolution model (MM5/Meteogalicia or HIRLAM/INM)
Three grids with 15Km, ~5Km and 1.8 km. Larger grid introduces a realistic large scale meridional pressure gradient and
Climatological forcing and run in the larger domain (Peliz & Dubert)
Realistic meteo forcing from August 2002

Sensitivity tests
hmin=40m, theta_b=0.2Broader density signature
hmin=40m, theta_b=0.0Enhanced mesoscale activity
hmin=10m, theta_b=0.0More intense IPC

Conclusions
We have set-up a realistic configuration for studying the poleward slope flow off N and NW Iberia
IPC exhibits variability in response to wind events.
On the north coast, wind forcing can be the dominant term in the penetration of IPC.
Our work in progress is an evaluation of physical terms; sensitivity to different parameters and setting-up other periods of simulation.
