| 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 of PDO has a relationship with global warming. |
