%X Empirical mode decomposition and Hilbert spectrum method are applied to the summer subtropical atmospheric system. It is analyzed the intrinsic mode functions (IMF) and Hilbert spectrum for the solution series of periodicity and vacillation states. The results show that the periodicity state stream function is usually made up of one main IMF component,and periodicity of this IMF component is as same as original serials. When the periodicity IMF component applied by Hilbert transform,instantaneous frequency ...
