High-latitude electromagnetic and particle energy flux during an event with sustained strongly northward IMF
We present a case study of a prolonged interval of strongly northward orientation of the interplanetary magnetic field on 16 July 2000, 16:00–19:00 UT to characterize the energy exchange between the magnetosphere and ionosphere for conditions associated with minimum solar wind– magnetosphere coupling. With reconnection occurring tailward of the cusp under northward IMF conditions, the reconnect...
متن کاملCLUSTER observations of electron outflowing beams carrying downward currents above the polar cap by northward IMF
Above the polar cap, at about 5–9 Earth radii (RE) altitude, the PEACE experiment onboard CLUSTER detected, for the first time, electron beams outflowing from the ionosphere with large and variable energy fluxes, well collimated along the magnetic field lines. All these events occurred during periods of northward or weak interplanetary magnetic field (IMF). These outflowing beams were generally...
متن کاملIonospheric flow during extended intervals of northward but By-dominated IMF
We present SuperDARN radar observations of the nightside high-latitude ionospheric flow during two 6hour intervals of quasi-steady northward interplanetary magnetic field (IMF). During both intervals (01:30–07:30 UT on 2 December and 21:00–03:00 UT on 14/15 December 1999), the solar wind and IMF remained relatively steady with Bz positive and By negative, such that the IMF clock angle was ∼−50 ...
متن کاملtranslating allusive devices:a survey of a portrait of the artist as a young man by james joyce
تلمیح یکی از عناصری است که تقریباً در همه ی متون ادبی یافت و باعث ایجاد شکاف های فرهنگی می شود. در این تحقیق به عنوان شکلی از بینامتنیت در ترجمه مورد توجه قرار می گیرد. تلاش شده است تا راهکارهای مترجمان برای ترجمه چهار نوع اسامی خاص و عبارات کلیدی تلمیحی (مذهبی، سیاسی، تاریخی و اسطوره ای) موجود در رمانِ چهره مرد هنرمند در جوانی به فارسی بررسی شود. این تحقیق مقایسه ای بر اساس راهکارهای ترجمه تلمیح...
15 صفحه اولThe UV aurora and ionospheric flows during flux transfer events
Far Ultra Violet (FUV) signatures in the polar ionosphere during a period of magnetopause reconnection are compared with ionospheric flows measured in the cusp ‘throat’ and dusk cell by the CUTLASS Hankasalmi HF radar. Regions of peak FUV emission in the 130.4 nm and 135.6 nm range, observed by the Polar spacecraft’s VIS Earth Camera, consistently lie at the turning point of the flows from the ...
