Abstract

We demonstrate extreme ionospheric response to the large interplanetary electric fields during the "Halloween" storms that occurred on October 29 and 30, 2003. Within a few (2 - 5) hours of the time when the enhanced interplanetary electric field impinged on the magnetopause, dayside total electron content increases of approx.40% and approx.250% are observed for the October 29 and 30 events, respectively. During the Oct 30 event, approx.900% increases in electron content above the CHAMP satellite (approx.400 km altitude) were observed at mid-latitudes (+/-30 degrees geomagnetic). The geomagnetic storm-time phenomenon of prompt penetration electric fields is a possible contributing cause of these electron content increases, producing dayside ionospheric uplift combined with equatorial plasma diffusion along magnetic field lines to higher latitudes, creating a "daytime super-fountain" effect.

Abstract

Prompt penetration electric fields (PPEFs) and the consequential dayside ionospheric superfountain (DIS) are reviewed. An example of O+ uplift to ~840 km altitude at ~0940 local time (DMSP F15) during the superstorm of 30 October 2003 is illustrated. The SAMI-2 model is modified to incorporate intense superstorm electric fields. With an inclusion of a ~4 mV/m eastward electric field, SAMI-2* modeling results show many of the expected DIS effects., isbn: 81-87099-40-2, Pages: 384-388

7. Dayside ionospheric (GPS) response to corotating solar wind streams

Abstract

The dayside ionospheric modifications associated with the three phases of corotating stream-generated magnetic storms (initial, main and recovery) are investigated. The high density heliospheric current sheet plasmasheet (HCSPS) pressure pulse impingements onto the magnetosphere, the collision of high magnetic field intensity corotating interaction regions (CIRs) onto the magnetosphere, and high speed stream Alfvénic interval ionospheric effects are all investigated using both GPS ground and satellite receiver data. The above results are compared with results associated with magnetic storms caused by interplanetary coronal mass ejections (ICMEs). The main effect found is that southward GSM Bz magnetic fields within CIRs cause an uplift of the dayside ionosphere with the consequence of enhanced ionospheric total electron content (TEC). This limited dayside effect is believed to be due to the variable magnetic field z-components within CIRs. Global dayside and nightside auroral zone ionospheric TEC enhancements are noted associated with the high solar wind Alfvénic intervals. Interpretation of our findings will be given, plus directions for future research in this new and emerging area of space weather., isbn: 978-0-87590-432-0, Pages: 245-270
