Abstract. One of current issues in the research of solar-terrestrial connections is development of the theory of solar winds. In this Paper, a simple idea of solar winds’ generation is presented based on the mechanic model. When a wave reaches the top layer of any chromospheres’ fragment and outputs of, such a wave tears off a thin layer of plasma and transfers its energy. Because of the thin structured fragmentations of chromospheres and the solar corona, the ejected clouds – micro-transients of plasma abandon without any hindrance the solar atmosphere. This is our version for a mechanism for formation of dynamic corona and solar winds, e.g., the model of corona formed by the streams erupted out of spicules is proposed. Extrapolation by our formula gives a correct meaning both in the speed as well as in density of the solar winds upto the Earth’s orbit , while the well-known formulae of Van de Hulst and others’ on the electron density in the solar corona do not recognize the extrapolation process, and basically interpolate via formulas with several parameters.
