The Changes Of The Length Of The Day And Geomagnetic Field Delay Related Analysis And Prediction

Use historical geomagnetic field model GUFM1, international geomagnetic reference field model and day long material, based on Matlab program the fitting toolbox, Fourier cycle analysis, cross-correlation calculation, analysis of practical techniques, long change and magnetic field between the parameters of delay relations, hopes to prove some scholars research conclusion, namely:the magnetic field parameters change staying ahead of the day long change for a decade or so.Research shows that:the long-term changes to the magnetic field parameters related with the long change is an objective existence, but on my research, is long in various magnetic parameters changes ahead10years or so. Analysis the reasons caused the delay relationship may be in nuclear curtain electromagnetic coupling process, because the nuclear magnetic field in the process of spread outward caused mantle weak electric conductivity...
