Top eight panels: the daily solar wind speed (black) vs. fractionation values of various elements (colors) from 2008 January 1 to 2008 April 22. Repeated sulfur enhancement within a certain wind speed pattern, as well as interesting correspondences among various elements (see Section 2 for detail), can be seen. Bottom four panels: the orientation of IMF fields (∼135° and ∼315° correspond to the inward and outward direction with respect to the nominal Parker spiral, respectively, 64 s average), O⁺⁷/O⁺⁶ (black) and C⁺⁶/C⁺⁵/10 (red) charge state ratios (2 hr average), the quantity ﹩(\delta v\cdot \delta B)/| \delta v| | \delta B| ﹩, which is a proxy of Alfvénicity (black for 64 s average and green for their 1 hr average), and the velocity fluctuations in normal (green) and tangential (red) direction (64 s average). The red and blue vertical lines mark the two kinds of slow wind that repeatedly appear during this period, one with sulfur enhancement and the other without sulfur enhancement, respectively.
