摘要: Comparison between observations of macrospicules and numerical jet models obtained in our previous one-dimensional hydrodynamic simulations suggests that Hα EUV unseen have different physical origins. are produced by pressure gradient force at the bright point middle or upper chromosphere. On other hand, shock waves which originate from network bright-points photosphere low chromosphere propagated through An essential difference two types is density ratio corona. The critical parameter causing this height points. general relation jets (including also regular spicules) points discussed.
