RESEARCH ON REBUILDING OZONE DYNAMIC SYSTEM OF ZONAL AVERAGE OVER THE TROPIC ZONE

The ozone data observed by TOMS in every 5°N are extended into the phase space to describe the characteristics of ozone with phase trace. First of all, the fractional dimension of the ozone layer is calculated. Then.the phase points are regarded as some discrete characteristics solution, and the parameters of mathematical model which describe the time variation of system state are retrieved, so that the nonlinear dynamic system which reflects the short-term variation of zonal average ozone layer over the tropics is rebuilt.
