| dc.description.abstract | 使用TIEGCM model模擬2001年地磁安靜狀態期間，場向電漿飄移速度與電漿密度分佈與華衛一號觀測資料進行分析比對。根據電漿連續方程式(continuity equation)，場向電漿速度的散度直接決定電漿密度的分佈情形。第二部分我們單獨分析TIEGCM模擬資料，控制不同的F10.7、高度、季節等參數，分別比較對於場向中性風速、場向擴散效應、場向電漿速度、電漿密度所造成的影響，有助於我們分辨那些是影響場向電漿運動速度的主要因素。 | zh_TW |
| dc.description.abstract | Using the TIEGCM model to simulate parallel B plasma velocity and plasma distribution which happened in 2001 quiet time. The satellite
data shows there is a large amount of plasma frequently piled up in LT12:00~16:00、MLAT15°~25°.Generally is called equator abnormal phenomenon (EIA).The simulate data shows the same phenomenon in relative position and the value also approaches equally.
We further analyzed parallel B plasma velocity.The simulated and observed data all shows that a smaller value(10~20 m/sec) in equator abnormal region,and a bigger value(50~80m/sec) outside of boundary region, therefore the plasma is unable to stable existence in this region.According to
continuity equation, divergence of parallel B plasma velocity direct influence plasma density distribution.
At second part,we alone analyzed the TIEGCM simulate result, and control different parameter(F10.7、altitude、season),It helps us to analyse which is the primary factor to affect plasma parallel B velocity. | en_US |
