Based on studies of the variance of water temperature, two methods for forecasting the surface temperature in the East China Sea were proposed in this paper. The first method,consisting of non-harmonic analysis and steady random extrapolapolation, is proposed to forecast the short term mean monthly and tenday sea surface temperatures. (S.S.T.).In the second method,the time (weight) coefficieats of the S.S.T. field are separated by orthogonal function,and then a non-harmonic analysis is made to establish the long-term and broad range mean monthly and ten-day S.S.T.forecasting technique.In the first metod, it is assumed that the variation of S.S.T.with time consists of periodic and random components.Applying the non-harmonic analysis to the former variation and the steady random extrapolation to the latter, the v.m.s.errors in the back prediction of mean monthly and ten-day S.S.T.for the total sea area are ±0.67℃ and ±0.87℃ respectively.
