Wavelet transform is a completely new mathematical analysis method developed in the early 1980's. It is suitable for studying local characteristics of signal. WT has been widely used in analysis of seismic data, image processing, analysis of sonic signal, fractal, sampling, turbulence, and many studies in atmospheric sciences and oceanography. Comparing with the traditional methods of mathematical analysis, enormous superiority of WT has been demonstrated. In this paper, on the basis of brief introduction of the defination and some foundamental concepts of WT, the application study of WT in atmospheric sciences are given with examples. At last, problem in use of WT and the potentiality are discussed.
