A new solar flare scenario is proposed based on high-beta plasma disruption. It is also proposed to interpret solar atmospheric structures and activities as "dissipative structure". In the standard model, the origin of solar activities is magnetic energy and of the mechanism of releasing magnetic energy is magnetic reconnection. In the present article, roles of plasma are stressed and the instability of plasma confined in the magnetic field in the solar atmosphere is attributed to the solar surface activities, especially solar flares. Nuclear fusion experiments in TOKAMAKs show that when the plasma density and temperature are higher, the plasma in the loop are disrupted due to ballooning instability. The same mechanism can be applied to magnetic loops in the solar atmosphere.
