Abstract:
The Earth shows a constant display of an organized complexity system, and its intrinsic capacity for sporadic self-or- ganization constitutes its fundamental and profound mysterious property. A graphical method derived from the logistic phase space of precipitation is proposed to identify periods of abundance-scarcity of rain as well as El Niño presence in order to cope with climate change. The most striking result is that the majority of El Niño events on this graph are cha- otic, in which the sign of the dominant eigenvalues of precipitation gives trends of scarcity on negative signs and abun- dance on positive signs, with eleven years periods.
