Impulse in global geomagnetic "secular variation", 1977-1979
Description (Dublin Core)
en-US
The global geomagnetic secular variation in the l960s and l970s was characterized by a rather rapid intensification which was shown to be of internal origin (Nevanlinna, 1980). An external 11-year wave could also be identified (Nevanlinna, 1980; Yukutake and Cain, 1979). In studying the global secular variation for the last few years, an even more rapid global change can be identified, namely a sudden enhancement followed by a deficit, lasting roughly two years from the end of 1977 to 1979. Here we demonstrate that the pulse is of external origin and that it resembles an intensification of the magnetospheric ring-current system lasting for about two years.
