Intense space storms: Critical issues and open disputes
[1] This paper addresses the question of particular characteristics and causes of intense space storms. We focus on several unresolved issues, which are critical to storm research and often nourish open disputes: the extent of interplanetary driving, the role of substorms in storm dynamics through the acceleration of particles to ring current energies, the identity of the lead agent of fast rin...
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 کاملResponse 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...
متن کاملMore frequent intense and long-lived storms dominate the springtime trend in central US rainfall
The changes in extreme rainfall associated with a warming climate have drawn significant attention in recent years. Mounting evidence shows that sub-daily convective rainfall extremes are increasing faster than the rate of change in the atmospheric precipitable water capacity with a warming climate. However, the response of extreme precipitation depends on the type of storm supported by the met...
متن کاملIdentification of possible intense historical geomagnetic storms using combined sunspot and auroral observations from East Asia
Comprehensive catalogues of ancient sunspot and auroral observations from East Asia are used to identify possible intense historical geomagnetic storms in the interval 210 BC–AD 1918. There are about 270 entries in the sunspot catalogue and about 1150 entries in the auroral catalogue. Special databases have been constructed in which the scientific information in these two catalogues is placed i...
