Solar-Flare-Initiated Shock Waves; Blast Waves Riding on the Solar Wind

摘要

Consider the speed of the solar flare initiated disturbance as having two separable components. These are: (1) the speed of the blast wave initiated by the impulsive release of energy by the solar flare and (2) the speed of the preexisting solar wind. In the solar wind frame the slope of the blast wave speed profile is -0.5. The average blast wave speed to an observation location is obtained by integrating the blast wave equation. The average disturbance speed in interplanetary space is the sum of the average blast wave speed and the solar wind speed.
