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.
