Research Abstract

In order to clarify the energy transfer processes of substorm-associated magnetic disturbances from higher to equatorial latitudes, and to understand global changes of the magnetospheric phenomena, we had carried out the magnetic and atmospheric electric fields, and aurora observations in Alaska and Siberia. In this year we did the following overseas field research : (1) We had installed a fluxgate magnetometer at Paratunk in Kamchtsuka, where low-latitude aurora sometimes appear.
(2) A co-investigator visited several institutes of Russian Academy of Science in Moscow to collect the solar and IMF data which are key parameters, controlling the occurrence of auroral substorms.
(3) Temporal observations of magnetic and atmospheric electric field were done in Argentina to check the electromagnetic environment variations.
(4) In Alaska, we also installed a fluxgate magnetometer at Kotzebue to detect auroral magnetic variations.
(5) All-sky TV camera and fluxgate magnetometer were shipped to IKF … More IA of Russian Academy of Science, Yakutsk, in order to observe auroral variations.
(6) Co-investigators in the University of Alaska were invited to the STE Lab., Nagoya University, and started the collaborative data analysis and studies on the auroral disturbances, the relationship between higher and lower latitude phenomena.
From these collaborative studies, the following results were obtained. [I] There are two generation mechanisms of low-latitude substorm-associated variations ; One is caused by an oscillation of field-aligned current intensity formed at high latitudes, and the other is a cavity-like oscillation excited in the inner magnetosphere.
[II] The low-latitude aurora must be excited during a substorm in the main phase of storm, when the substorm-associated electric field could accelerate hot-ring current proton into the inner magnetosphere. An interaction between the hot plasma and cold plasma in the plasmasphere must produce field-aligned electron precipitation and an upward FAC at lower latitudes with ionospheric equivalent vortex structure.
