摘要
First of all,for the odd and even symmetry components of both hemisphere circulations are given the absolute and relative measurements with which to examine the seasonal change and interannual abnormality of the components on the 1980—1986 monthly mean 500-hPa height charts.Results show a noticeable relationship between a major El Nino event and the component anomaly,with the even part anomaly almost-synchronizing with its culmination and that of the odd part about half a year prior to the event,a relation that is still more sharply manifested at the 200-hPa height field.
