Variation of KUROSHIO-Induced Geomagnetic Total Intensity in Miyakejima Island

Masahiro SASAOKA and Akira YAMAZAKI


   We researched the contribution of KUROSHIO-Induced geomagnetic total intensity in Miyakejima Island between 2010 and 2011. In variations of the geomagnetic total intensity observed in Miyakejima Island, the southern coastal station was strongly correlated with the southern inland stations but rarely correlated with the northern inland station. During the periods of Kuroshio Current approaching Miyakejima Island, the geomagnetic total intensity in the southern inland stations was up only by the variation due to Kuroshio Current. It is suggested that KUROSHIO-Induced geomagnetic total intensity of the northern inland stations might not be inferred from that of the southern coastal station necessarily.
