| Abstract: | Data sets of the changes of the length of day, the sea surface temperature in the eastern Pacific and of the sea level in Hong Long from tide gauge observations are used to analyze and reveal the reflections in the observations of the length of day and the sea level changes concerned with the premonitory phenomenon of next El Ni(n)o event. The results from this study indicate that a new El Ni(n)o event has been brewing with the ending of the strong La Nina event that started in early summer of 1998. The estimated formation period of the new El Ni(n)o event will begin before the end of 2000, and the peak period may be reached at around the end of 2001. |
