Numberical Modeling And Morphological Observation Of Solar Spicules

This paper introduces the related theories and research progress of spicules from the following aspects and studies on the phenomenon of spicule wave fluctuation,“double-line”and“group motion”observed based on Hinode/SOT:In the first chapter,we introduced the structure of the solar atmosphere and the significanceof this study.We familiarised the content and the development of the MagnetoHydroDynamics(MHD)numerical modeling of the spicules in the chapter 2,this includes:acoustic wave models,Alfvén wave models,and magnetic reconnection models.In third chapter we introduced the basic information of Hinode satellites,including:SOT,XRT and EIS telescopes.And then we introduced Hinode/SOT data processing method.Chapter 4 highlighted several classic corona heating models,and then we introduced the total amount of spicules and average flux density(Include Type I and Type II).The number of type I and II spicule is about 10~6and10~5,respectively.Type II spicule is more energetic comparing to type I,and it is likely that type II spicule plays the major role in the corona heating.In the fifth chapter,we introduced the research progress of the spicule wave phenomenon,and the MHD wave.Phenomena of“two-line”and“group motion”of spicules were treated in chapter6.Finally,we summarised the current spicules research results and future research directions.
