These two pictures show the speed of the solar wind. The speed
of the solar wind was measured by the Ulysses spacecraft. The
red and blue arrows show how fast the solar wind was "blowing".
Longer arrows show higher speeds. The picture on the left shows
the Sun at "solar min" when there are few sunspots. The picture
on the right shows the "solar max" period of a sunspot cycle.
That's when the Sun is very active and there are usually lots of
sunspots. At solar min, the fast solar wind (~750 km/sec) flows
outward from coronal holes near the poles. The slow solar wind
(~400 km/sec) flows more slowly from the Sun's equator. At solar
max the Sun's magnetic field is a scrambled mess. The speed of
the solar wind is not really related to latitude at solar max.
