The solar wind is a stream of charged particles (i.e., a plasma) which are ejected from the upper atmosphere of the sun.

The
"Plumes" of outward flowing, hot gas in the Sun's atmosphere may be one source of the solar "wind" of charged particles.

Solar wind (stream of particles from the Sun) is usually around 0.001 joules per square meter per second -- about a million times less than sunlight.

It takes the solar wind about 4.5 days to reach Earth; it has a velocity of about 250 miles/sec (400 km/sec). Since the particles are emitted from the Sun as the Sun rotates, the solar wind blows in a pinwheel pattern through the solar system.

Solar Wind: The solar wind streams off of the Sun in all directions. The source of the solar wind is the Sun's hot corona, whose temperature is so high that the Sun's gravity cannot hold on to it.

- Supersonic flow of high-speed charged particles continuously blowing off a star (mostly e- and p+). When originating from stars other than the Sun, it is sometimes called a "stellar" wind.

Solar wind--hot solar plasma spreading from the solar corona in all directions, at a typical speed of 300-700 km/sec. It is caused by the great heat of the corona.

Solar Wind
a flow of charged particles that travels from the Sun out into the Solar System.

: The stream of charged particles and atoms (mainly ionized hydrogen but actually a mixture of all atoms in the Sun) moving outward all the time from the Sun with low velocities in the range 300-500 kilometers per second.

Solar wind. The flow of particles from the Sun in every direction. The 'wind' is an ever present feature of the Sun but the intensity of the wind is dependant on Solar activity.
