Temperature perturbations associated with the propagation of magneto-acoustic waves in a magnetic flux tube. Two scenarios of wave excitation, viz. granular buffeting and swirly motion are studied. Buffeting by granule are likely to generate strong slow and fast magneto-acoustic waves compared to swirly motions as evident from the temperature fluctuations seen in the case of horizontal excitation.
