| Research Abstract |
We studied the magnetic energy dissipation mechanism of the fully collisional and weakly ionized plasma in the solar lower atomosphere by numerical simulation and analysis of the solar chromospheric jets observed by Solar Optical Telescope on Board Hinode space craft. We found that, similarly to the case in the fully ionized solar corona, intermittent and fast magnetic reconnection associated with plasmoids ejection is occurring also in the solar chromosphere. The cause of such intermittent and fast magnetic reconnection is the inhomogeneity of the ambipolar diffusion.
