solar wind
solar wind General term for the stream of high-energy particles (mainly protons, electrons, and alpha particles) emitted by the
Sun. The particles have velocities of hundreds of kilometres per second and ‘wind’ strength is thought to be greatest during periods of maximum solar activity. In the neighbourhood of the
Earth the solar wind has velocities in the range of 300–500 km/sec and an average density of 10
7 ions/m
