dc.description.abstract研究發現於南半球夏天的晚上威德海地區電離層電子濃度會比白天時的濃度還高,此稱之為威德海異常(Weddell Sea Anomaly; WSA)。本論文研究台俄衛星(Experimental Scientific Education Micro-Satellite/Tatyana-2, ESEMS/T-2)電漿電子溫度計 (Electron Temperature Probe, ETP) 酬載資料,發現2009年12月至2010年1月,南半球夏季上午1000LT威德海地區電離層電子溫度會異常高溫。相互比對台俄衛星、法國DEMETER衛星、福爾摩沙衛星3號觀測,證實夜間電子濃度異常增大而其白天電子溫度異常高溫之存在。比較觀測與水平風場模式(Horizontal Wind Model, HWM93)模擬結果,說明威德海電離層異常與熱氣層子午風經度之日變化有關。 zh_TW
dc.description.abstractPrevious studies show that the ionospheric density is grater in the summer nighttime than daytime around the Weddell Sea region, which is named Weddell Sea Anomaly (WSA). In this research, measurement of an electron temperature probe (ETP) onboard the Experimental Scientific Education Micro-Satellite/Tatyana-2 (ESEMS/T-2) at 1000LT and 2200LT during December 2009-January 2010 are analyzed. ESEMS/T-2 observes anomalous enhancements in the ionosphere electron temperature, while DEMETER probes anomalous electron temperature enhancements and electron density reductions concurrently. Cross-comparisons between observations among ESEMS/T-2, DEMETER, and FORMOSAT-3/COSMIC that confirms existences of the nighttime electron density and daytime electron temperature anomalies over the Weddell Sea region. A further investigation on the observations and simulations of the horizontal wind model HWM93 shows that the northward meridional wind along the Earth’s magnetic field is essential to form the electron density enhancement in the Weddell Sea latitude. en_US
