Song, X. Feng, F. Shen, J. Guo] In the present investigation we measure the differential rotation of strong magnetic flux during solar cycles 21 - 23 with the method of wavelet transforms. We find that the cycle-averaged synodic rotation rate of strong magnetic flux can be written as ω=13.47−2.58sin 2 θ or ω=13.45−2.06sin 2 θ−1.37sin 4 θ, where θ is the latitude. They agree well with the results derived from sunspots. A north-south asymmetry of the rotation rate is found at high latitudes (28°<θ<40°). The strong flux in the southern hemisphere rotates faster than that in the northern hemisphere by 0.2deg day−1. The asymmetry continued for cycles 21 - 23 and may be a secular property.
