Ionospheric characteristics above martian crustal magnetic anomalies
33.02 DPS Conference 2005.09.06 We studied several thousand electron density profiles from the Mars Global Surveyor Radio Science experiment. Electron densities in some of these profiles change significantly over vertical distances as short as 1--2 km, often causing localized ``bite-outs''. These ``anomalous'' profiles are preferentially located above crustal magnetic anomalies. Anomalous featu...
متن کامل: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
15 صفحه اولIonospheric cusp flows pulsed by solar wind Alfvén waves
Pulsed ionospheric flows (PIFs) in the cusp footprint have been observed by the SuperDARN radars with periods between a few minutes and several tens of minutes. PIFs are believed to be a consequence of the interplanetary magnetic field (IMF) reconnection with the magnetospheric magnetic field on the dayside magnetopause, ionospheric signatures of flux transfer events (FTEs). The quasiperiodic P...
متن کاملIonospheric f oF2 anomalies during some intense geomagnetic storms
The global evolutions of f oF2 anomalies were examined for three very intense geomagnetic storms, namely the Halloween events of October–November 2003 (Event X, 29–30 October 2003, Dst −401 nT; Event Y, 20–21 November 2003, Dst −472 nT), and the largest Dst storm (Event Z, 13–14 March 1989, Dst −589 nT). For Event X, troughs (negative storms) were clearly seen for high northern and southern lat...
متن کاملLow-frequency anomalies in dynamic localization.
Quantum mechanical spreading of a particle hopping on tight binding lattices can be suppressed by the application of an external ac force, leading to periodic wave packet reconstruction. Such a phenomenon, referred to as dynamic localization (DL), occurs for certain 'magic' values of the ratio Γ = F0/ω between the amplitude F0 and frequency ω of the ac force. It is generally believed that in th...
