MSTID activity is defined as    δ  I  /    I    ¯     , where    δ  I    is standard deviation of the TEC perturbations over Kokubunji within 1 h, and      I    ¯      is the background TEC. By analyzing nighttime-averaged (19-02 LT) values of MSTID activity and      E    s      layer parameters, we find that the MSTID activity is closely correlated with      f    0      E    s      and      f    0      E    s    -    f    b      E    s     . This result suggests that MSTID and the spatial structures of      E    s      layer could be generated by an electro-dynamical coupling process between the      E    s      layer and F region through polarization electric fields. Furthermore, we suggest that the appearance of the      E    s      layer in the summer hemisphere could play an important role in generating MSTIDs in both hemispheres."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380021391865408402","@type":"Researcher","foaf:name":[{"@value":"Y.
