An analyzing method of quasi-monochromatic waves is proposed. Some periods are selected within the band width and wavelet transformations are operated on objective time sequential data using the fixed scale parameters corresponding to the selected periods. Transformations are repeatedly operated to emphasize the distributions of signal intensities every selected periods on time axis. Availability of this method is confirmed by test data and this method is actually applied into GMS VISSR IR time sequential data to know the details of climatic behavior regarding the waves around the equator. The results show that the method is useful and succeeds to emphasize the distributions of the objective periods out of quasi-monochromatic waves.
