| Abstract: | The multi-time scale and abrupt characters are obtained based on monthly mean temperature data of Heilongjiang Province during the recent 50 years by using Morlet wavelet transformation, and some comparisons are made by applying both wavelet transformation and Fourier spectral analysis to the data. The results are of referential importance in short-term climate forecast for the temperature of Heilongjiang Province. |
