On some interrelations in the dynamics of tropical cyclonic activity

A chronological series of tropical cyclones is a flow of cyclonic activity where the bursts and calms of cyclonic activity alternate. Some interrelations between the stages of cyclonic activity have been studied. We derive the dependence that the length of the time interval between two consecutive of bursts of cyclonic activity have on a number of parameters of the first burst and the calm between the bursts. We find that one can estimate the intensity of the subsequent burst on the basis of the intensity of the previous burst. We derive a regression between the value of burst energy at a given time and the value of energy in the same burst for 1–3 days.
