| Summary: | A new detection method has been proposed to study the transition
process of abrupt climate change. With this method, the climate system
transiting from one stable state to another can be verified clearly. By
applying this method to the global sea surface temperature over the past
century, several climate changes and their processes are detected, including
the start state (moment), persist time, and end state (moment). According
to the spatial distribution, the locations of climate changes mainly have
occurred in the Indian Ocean and western Pacific before the middle twentieth
century, in the 1970s in the equatorial
middle-eastern Pacific, and in the middle and
southern Pacific since the end of the twentieth century. In addition, the
quantitative relationship between the transition process parameters is verified
in theory and practice: (1) the relationship between the rate and stability
parameters is linear, and (2) the relationship between the rate and change
amplitude parameters is quadratic. |
