The height dependence of temperature : velocity correlation in the solar photosphere
/ Abstract
We derive correlation coe±cients between temperature and line-of-sight velocity as a function of optical depth throughout the solar photosphere for the non-magnetic photosphere and a small area of enhanced magnetic activity. The maximum anticorrelation of about i0:6 between temperature and line-of-sight velocity in the non-magnetic photosphere occurs at log ?5 = i0:4. The magnetic eld is another decorrelating factor along with 5-min oscillations and seeing.
