Structujre and dynamic of the ozone field above the Northern hemisphere

Structures and evolution of the total ozone content (TOC) above the Northern hemisphere is considering in this paper. Averaged monthly meanings of (TOC) obtained in a result of the probing from Nimbus satellite in the period from 1979 to 1993 and EP/TOMS data from 1996 to 2003 served as materials for our research. We use the complex approach to the research of TOC as a variable natural field (NF). That approach consists of two stages: 1) Assigning components from the time rows in the each point of space. It would let to form any set of parameters for the time rows compact description. That set includes; average meaning, dyspersia, phase, and parameters of the trend and seasonal movement is proposed, that each component of the time row be conditioned by their natural mechanism action in their time scale. 2) Classification of the all components, that would let us to recognize regions with approximately similar character of evolution or separate time periods on the set time interval, where similar NF behavior occurred. As a result we have detected three precise regions of decreased of TOC and closed region of increased of TOC. Moreover, it was shown that the structure of ozone field is invariable in the course of time
