| Zusammenfassung |
| A climate system which is transitioning from one state to another is known
as an abrupt climate change. Most of the recent studies regarding abrupt
climate change have focused on the changes occurring before and after the
abrupt change point, while little attention has been given to the
"transition process" which occurs when the system breaks away from the
original state to a new state. In this study, a novel method for analyzing
the process of abrupt climate change was presented. By using the
mathematical model based on the logistic model, the process of the abrupt
change could be analyzed and divided into different phases which include
start moment, end moment, stable state, and unstable transition state.
Meanwhile, the method was confirmed to be effective by testing in a study of
Pacific decadal oscillation (PDO) time sequence, and the results of this
study specify that this abrupt change process (ACP) of PDO has a relationship with
global warming. |
