Theory of simplex projection operator and its application to analysis data Ⅱ.Application to forecast SST and Qingdao air temperature

Phase space theory is used to analyze the day SST of equatorial local area and nine moving average cn}th air temperature of Qingdao(NNIAMAT).The results show that the correlation dimension and embedding dimension of NMAMAT and SST are 5.83,8,3.93(anti-El Niňo) or 4.37(El Niňo),11(anti-El Niňo) or 9(El Niňo),respectively.Ihe SST of El Niňo and anti-El Niňo can be described as chaotic phenanenon.The correlation dimension increase and embedding dimension decrease of El Niňo SST slaw that the SST iner-structure during El Niňo period is oanplex and implies nonlinear interaction increase.The above parameters and the forecast method of simplex projection operator are used to predict the time series date of SST and NMAMAT,and the biggest prediction relative etaots ad SST and NMAMAT are 0.42%,7.4% within the first eight points,respectively.
