Analysis of Storm Sudden Commencements for the Years 18681967
A list of a series of 2462 ssc's was made by studying the 100-year magnetic records in two antipodal subauroral observatories and in one low-latltude observatory. Various statistical' results are set forth. The negative correlation between ssc amplitude and ri'se time postulated by Desster et al. (1960) seems to be true for the more rapid ssc's (1-4 min). Yearly numbers of ssc's are much better...
متن کاملCoronal mass ejection–driven shocks and the associated sudden commencements/sudden impulses
[1] Interplanetary (IP) shocks are mainly responsible for the sudden compression of the magnetosphere, causing storm sudden commencement (SC) and sudden impulses (SIs) which are detected by ground-based magnetometers. On the basis of the list of 222 IP shocks compiled by Gopalswamy et al. (2010), we have investigated the dependence of SC/SIs amplitudes on the speed of the coronal mass ejections...
متن کاملSpace weather and interplanetary shocks
São discutidos nesse artigo alguns conceitos básicos relacionados ao clima espacial no ambiente próximo da Terra. Devido ao desenvolvimento tecnológico dos anos recentes, o clima espacial tornou-se um tema importante de pesquisa. Os avanços da área se devem principalmente à sua aplicabilidade nos sistemas tecnológicos tanto no espaço próximo quanto na superf́ıcie da Terra. Dentre os diversos tem...
متن کاملParticle Acceleration at Interplanetary Shocks
The acceleration of interstellar pick-up ions as well as solar wind species has been observed at a multitude of interplanetary (IP) shocks by different spacecraft. The efficiency of injection of the pick-up ion component differs from that of the solar wind, and is strongly enhanced at highly oblique and quasi-perpendicular shock events. This paper expands upon previous work modeling the phase s...
متن کاملSignatures of storm sudden commencements in geomagnetic H, Y and Z ®elds at Indian observatories during 1958±1992
The work describes an intensive study of storm sudden commencement (SSC) impulses in horizontal (H), eastward (Y) and vertical (Z) ®elds at four Indian geomagnetic observatories between 1958±1992. The midday maximum of DH has been shown to exist even at the low-latitude station Alibag which is outside the equatorial electrojet belt, suggesting that SSC is associated with an eastward electric ®e...
