| 内容記述 | It has been reported by Wilcox et al. (1973, 1974) that the solar magnetic sector structure extended away from the sun by the solar wind has an effect on the terrestrial atmospheric vorticity, the effect being a decrease in the vorticity area index with a width of about 5 days and a minimum 1 day after the sector boundary is swept past the earth by the solar wind. In the present study the vorticity area index is filtered so as to reject variations with periods less than 3 days or greater than 13 days. The 500 mb vorticity area index is used since the observations are more homogeneous. The persistence of the solar sector/atmospheric vorticity effect in the new data when the number of sector boundary passages is increased from 54 to 131 and in the independent latitude zones 35 deg N to 55 deg N and greater than 54 deg N, as well as the greater depth of the effect near sector boundary passages as compared with all other minima, suggest that the effect is real. This is further strengthened by the analysis of Hines and Halevy (1975). |
