A STUDY ON THE UNITED TIME-SPACE STRUCTURE OF 500 HPA MONTHLY MEAN HEIGHT

In this paper,500 hPa monthly mean geopotential height field has been analysed to determine the dominant modes of united spatial,seasonal and interannual varioability.A time-space synthetic empirical orthogonal function (EOF) analysis is used to reveal the modes which explain most of the variance for the period 1951-1984.The EOFs reveal the abrupt seasonal change and rhythm of atmospheric general circulation in Nothern Hemisphere.Time series associated with the EOFs reveal quasi-period fluctuations and the climatic jumps.
