In this paper a modified ensemble empirical mode decomposition (EEMD) method is presented, which
is named winning-EEMD (W-EEMD). Two aspects of the EEMD, the amplitude of added white noise and the
number of intrinsic mode functions (IMFs), are discussed in this method. The signal-to-noise ratio (SNR) is used
to measure the amplitude of added noise and the winning number of IMFs (which results most frequency) is used
to unify the number of IMFs. By this method, the calculation speed of decomposition is improved, and the relative
error between original data and sum of decompositions is reduced. In addition, the feasibility and effectiveness of
this method are proved by the example of the oceanic internal solitary wave.
