Geomagnetic storms driven by ICME- and CIR-dominated solar wind
[1] The interaction of the solar wind and the Earth’s magnetosphere is complex and the phenomenology of the interaction is very different for solar wind dominated by interplanetary coronal mass ejections (ICMEs) compared to solar wind dominated by corotating interaction regions (CIRs). We perform a superposed epoch study of the effects of ICMEand CIR-dominated solar wind upon the storm-time pla...
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 کاملSolar wind-magnetosphere coupling efficiency during ejecta and sheath-driven geomagnetic storms
We have investigated the effect of key solar wind driving parameters on solar wind-magnetosphere coupling efficiency during sheath and magnetic cloud-driven storms. The particular focus of the study was on the coupling efficiency dependence with Alfvén Mach number (MA). The efficiency has been estimated using the dawn-dusk component of the interplanetary electric field (EY ), Newell and Borovsk...

بررسی رابطه دانش همنشینی لغات و مهارت نوشتاری در زبان انگلیسی چکیده این پژوهش درصدد آن است تا سه مسئله زیر را مورد بررسی قرار دهد: الف) وجود یا عدم وجود رابطه بین دانش زبان آموزان در حوزه همنشینی لغات با یکدیگر و دانش آنها در مهارت نوشتاری زبان انگلیسی؛ ب) یافتن پاسخی به این سوال که آیا تمامی انواع همنشینی های لغوی زبان انگلیسی به یک میزان برای زبان آموزان دشوارند یا خیر؛ پ) مقایسه زبان آمو...
15 صفحه اولResponse of the Antarctic Ionosphere to Some Intense Geomagnetic Storms
Method: For this purpose, foF2 data from four Antarctic stations were analyzed during three intense magnetic storms occurred in high solar activity (years 2002 and 2003). In general, negative storm effects irrespective of the local time were observed during the first part of the storms (main phase). Negative effects were also observed more often than positive effects during the first part of th...
