摘要A possible correlation between the magnetic and velocity fields has been analyzed based on the SOHO/MDI magnetograms and Dopplergrams. It is found that the observed large-scale weak magnetic field (weaker than 50 G (gauss)) is correlated with the velocity statistically. The curves of u . b with latitude, where u and b are the velocity and magnetic fields in a rectangular region (+/- 15(degrees) in longitude, +/- 45(degrees) in latitude) on the Sun, show the same patterns in the years 2000, 2004, and 2007. The patterns indicate that u and b are positively correlated near the equator but are anti-correlated at the middle latitudes. For a strong magnetic field between 50 G and 3000 G, the curves of u . b with latitude show the same tendencies at the middle latitudes. Near the equator, however, the slope of the curve is positive in 2000 and is negative in 2004 and 2007. In addition, we give an estimation for the amplitude of the cross helicity h (chi) (h(chi) = (u . b) over bar) inferred from the MDI data, which is of the order of 10(3) G m s(-1) near the center of the solar disk.
