| Abstract: | Using Marr wavelet and Morlet wavelet transforms, the variations of surface air temperature and yearly precipitation in Yunnan Province during the last hundred years are analysed. Some multi time scale and jump features of the variations have been discovered. These features are very important in short_range climate forecast for Yunnan Province. They give the multi time scale pattern and the background of Yunnan climate changes. |
