The solar wind streams plasma and particles direct from sun
out into area. Though the wind is constant, its properties arent. What
causes this stream, and the way will it affect the earth ?
Windy star
The corona, the suns outer layer, reaches temperatures of up to 2 million degrees fahrenheit ( 1. 1 million celsius ). At this level, the suns gravity cant hold about the rapidly moving particles, and this streams from the the star.
The suns activity
shifts within the course of its 11-year cycle, with sun spot numbers,
radiation levels, and ejected material changing after a while. These
alterations affect the properties of one's solar wind, as well
as its magnetic field properties, velocity, temperature and density. The
wind too differs based mostly on where by the sun
it comes from and exactly how quickly that portion is rotating.
The velocity of
one's solar wind is higher over coronal holes, reaching speeds of up to
500 miles ( 800 kilometers ) per second. The temperature and density over
coronal holes are low, and of course the magnetic field is weak, therefore
the field lines are open to house. These holes occur along at
the poles and low latitudes, and reach their largest when activity by
the sun is at its minimum. Temperatures within the whole fast
wind will reach up to 1 million degrees f ( 800, 000 c ).
Along at the coronal
streamer belt close to firmly the equator, the solar wind
travels a lot of slowly, at around 200 miles ( three
hundredunited nations monitors. The unarme km ) per second. Temperatures within
the whole slow wind reach up to 2. 9 million f ( 1. 6 million c ).
