Abstract

Abstract

The chaotic systems of average monthly air temperature of Qjngdao (SATQ) and the day SST of equatorial local area (DSSEI,A) are firstly studied by means of the sequency spectral method.It is shown that SATQ contains one-a period of predominant oscillation, two-a periods lower frequency oscillatian and 90-d, 63-d, 50-d, 40-d and 29-d lower frequency periods oscillation in D6SELA.Further-more, the discrepancies between sequency spectrum and frequency spectrum are compared in this paper.
