Statistical analysis of relativistic electron energies for cyclotron resonance with EMIC waves observed on CRRES
[1] Electromagnetic ion cyclotron (EMIC) waves which propagate at frequencies below the proton gyrofrequency can undergo cyclotron resonant interactions with relativistic electrons in the outer radiation belt and cause pitch-angle scattering and electron loss to the atmosphere. Typical storm-time wave amplitudes of 1–10 nT cause strong diffusion scattering which may lead to significant relativi...
متن کاملThe link between a detached subauroral proton arc and a plasmaspheric plume
[1] Observations of detached subauroral proton arcs by the FUV instrument on the IMAGE spacecraft have been recently reported and shown to be produced by ring current ions precipitating in the afternoon local time sector during geomagnetically disturbed periods. Data from June 18, 2001 show a direct link between a subauroral proton arc and a global observation of a plasmaspheric plume by the IM...
متن کاملModeling radiation belt electron dynamics during GEM challenge intervals with the DREAM3D diffusion model
[1] As a response to the Geospace Environment Modeling (GEM) “Global Radiation Belt Modeling Challenge,” a 3D diffusion model is used to simulate the radiation belt electron dynamics during two intervals of the Combined Release and Radiation Effects Satellite (CRRES) mission, 15 August to 15 October 1990 and 1 February to 31 July 1991. The 3D diffusion model, developed as part of the Dynamic Ra...
متن کاملglobal results on some nonlinear partial differential equations for direct and inverse problems
در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...
Probing the relationship between electromagnetic ion cyclotron waves and plasmaspheric plumes near geosynchronous orbit
[1] Plasmaspheric plumes created during disturbed geomagnetic conditions have been suggested as a major cause of increased occurrences of electromagnetic ion cyclotron (EMIC) waves at these times. We have catalogued occurrences of strong Pc1 EMIC waves from 1996 through 2003 at three automated geophysical observatories operated by the British Antarctic Survey at auroral zone latitudes in Antarc...
