안녕하세요. 우주과학과 우주탐사학과 여러분.
세미나 공지 드리겠습니다.
이번 세미나는 18일 (화) 오후 4시 30분 천문대 영상실에서 있습니다.
Meteorological College의 Shigeru Fujita 교수님께서 "Generation of thmagnetospheric convection" 이라는 제목의 강연을 해 주실 예정입니다.
강연은 영어로 진행됩니다.
세미나 참석을 원하시는 분은 세미나 시작 10분 전까지 입실해 주시기 바랍니다.
많은 참석 부탁드립니다. 감사합니다.

Dear Colleagues,

Title : Generation of the magnetospheric convection

 The magnetospheric convection is the fundamental process in which all global magnetospheric phenomena like a substorm occur.  The convection process has been widely explained with Dungey convection model [1961].  On the other hand, we developed a global MHD simulation which reproduces the magnetospheric process precisely.  Then, it is very surprising that the Dungey convection model is not reviewed by using the MHD simulation except Tanaka [2007]. I point out three defects of the Dungey model.  The first defect is that the Dungey convection model does not consider plasma pressure.  The second one is that the Dungey convection model does not consider the three-dimensional topology of the magnetic field merging in the dayside magnetopause.  The last one is that the Dungey convection model is a cartoon physics without quantitative evaluations of physical principle.  I will present mainly the second topic in this lecture.
