Abstract: We investigated the chromospheric dynamics of plage area. From our spectroscopic analysis of the CaII K line, we have found that their periodic variations are due to the propagation of acoustic waves from the lower layers. Another observational work on Hinode CaII H images, gave us a new result that there are numerous spicular jets in plage area, thanks to the stable observing condition of Hinode. The present paper is an extended abstract of our works which will be published fully in our future papers.
