Abstract
In this paper the Morlet complex wavelet munction was applied to analyze the evolution features of multi-scale wave-intensity during a torrential rain process.Separating the suhsynoptic scale system on temperature of black body(TBB) fields during a torrential rain process over the Middle and Lower Reaches of Changjiang River in the last dekad of July 1998,the evolution of multi-scale wave-intensity can be expressed by wavelet modules,and its coherence was investigated with the cross spectrum between the multi-scale waves.The results show that the process of the accumulation and release on the energy of meso-β scale system was shown in the torrential rain process,and the meso-α scale system had an interference effect on the meso-β system in a shorter period.
