Abstract

Two issues relevant to the best choice of time delay for phase space reconstruction are further studied by using the time series of GMS-5 11μm IR channel brightness temperature observations of rainstorm processes occurred in Wuhan area in China in July and in August of 1998. Periodic components existing in the satellite signals are investigated, first. The results demonstrate that the periodic components have noticeable influence on the choice of the optimum time delay. A new algorithm - the derivative method - is then developed for the extraction of possible periodic components from the time series. The advantages of this method and its importance are discussed.
