ADVANCES IN STATISTICAL METEOROLOGY IN CHINA IN RECENT YEARS

Great abvances in statistical meteorology have been made in recent years in China. The main points are as follows: Introducing entropy principle into meteorology, entropy meteorology is founded; introducing memory function, self-memorization equation of atmospheric motion is derived; the fuzzy reasoning is introduced into meteorology; using the method of nonlinear dynamics in researches of climatology, some forecasting schemes of phase space are proposed; Chebyshev polynomial is generalized at irregular grids and an it erative scheme for for ecast of time series is proposed; the wavelet transform is used in researches on climatology; Logistic discrimination is used in meteorology and quadratic discrimination are stepwise discrimination are investigated; the theory on grey system and the multilevel recursion method proposed by Chinese scientists are introduced into meteorological for ecast. In addition, complex empirical orthogonal function, singuler value decomposition, projection pursuit, principal oscillation patterns, et al. are also introduced.A bove methods have come in to play agreat roles in operational weather forecasts.
