Short summary

The commonly used CWT method shows advantages in revealing signals' broad-scale periodicities, but also shows disadvantages in revealing fine-scale periodicities because of the embedded mode-mixing problem, which have been effectively improved by combining the improved HHT method. This novel idea is also helpful for many kinds of signals. Another important innovation is introducing the XWT and WTC methods into studying the interaction process between precipitation and salinization dynamics.
