Popis: | 第9回宇宙科学シンポジウム(2009年1月6日-7日, 宇宙航空研究開発機構宇宙科学研究本部) Space weather is complex, and different physical processes mutually interact. Therefore, it is an important task to develop the integrated numerical model to understand not only the mechanism of each elementary process in solar terrestrial connection system but also the system dynamics of space weather event. Based on this motivation, we have been developing a new type of space weather modeling framework. The framework consists of the four different sub-models, which are interlocked each other. Each model can simulate the onset of solar flare, the formation of coronal mass ejection (CME), the propagation of interplanetary CME (ICME), and the geomagnetic impact, respectively. As the first trial, we have applied the new model to the space weather event caused by the X-class flare occurred on December 13, 2006. First, we performed so-called "data-driven" three-dimensional magnetohydrodynamic (MHD) simulation of the solar flare eruption using the nonlinear force-free magnetic field of active region NOAA 10930, which was reconstructed from the vector magnetogram observed by Solar Optical Telescope (SOT) aboard Hinode. Second, using the results of this flare simulation as the boundary condition of the global corona model, the formation of CME was investigated. Finally, the result of the global corona model will be transmitted to the interplanetary model which simulates the propagation of ICME. On the basis of the simulation results, capability of our space weather framework and some essential problems of integrating each codes are discussed 形態: カラー図版あり 資料番号: AA0064293119 |
