| Abstract: |
In order to discuss the propagation of Alfvén wave
in the real solar atmosphere,
we calculate three dimensional magnetic field
using
magnetic field observation obtained with Hinode
and a high resolution potential field model.
The modeled field reproduces fun out (canopy) structure
rooted to patchy concentrations of magnetic flux (kG-patches) in the polar region.
Combined with a atmosphere model,
the model shows that
most of the Alfvén wave propagating along the magnetic field lines
can hardly pass through the transition region
due to reflection there.
The model suggests that
strong concentration of the magnetic field
may make retardation of Alfvén wave phase between
neighboring field lines rooted on the edge of the canopy.
The situation may be potential situation for
Alfvén wave dissipation due to phase mixing process. |
