The solar magnetic sector structure appears to be related to the average area of high positive vorticity centers (low-pressure troughs) observed during winter in the Northern Hemisphere at the 300-millibar level. The average area of high vorticity decreases (low-pressure troughs become less intense) during a few days near the times at which sector boundaries are carried past the earth by the solar wind. The amplitude of the effect is about 10 percent.
太阳磁扇区结构似乎与北半球在 300 毫巴高度冬季观测到的高正涡度中心（低压槽）的平均面积有关。在太阳风将扇区边界带至地球附近的几天内，高涡度的平均面积减小（低压槽变得不那么强烈）。该效应的幅度约为 10%。
