One of the future challanges for helioseismology is the measurement of the solar meridional circulation, as this flow is needed in flux-transport dynamo models to explain, e.g., the length of the solar cycle. However a doubtfree seismic measurement of this flow throughout the full convection zone does not exist so far.
Here, I present estimates obtained from global and local seismic techniques how the meridional flow affects solar oscillations and to which extent in depth the meridional flow can be measured.
