Thermospheric mass density variations during geomagnetic storms and a prediction model based on the merging electric field
With the help of four years (2002–2005) of CHAMP accelerometer data we have investigated the dependence of low and mid latitude thermospheric density on the merging electric field, Em, during major magnetic storms. Altogether 30 intensive storm events (Dstmin <−100 nT) are chosen for a statistical study. In order to achieve a good correlation Em is preconditioned. Contrary to general opinion, E...
متن کاملThermospheric zonal temperature gradients observed at low latitudes
Fabry-Perot interferometer (FPI) measurements of thermospheric temperatures from the Doppler widths of the OI 630 nm nightglow emission line have been carried out at Cachoeira Paulista (23◦ S, 45◦ W, 16◦ S dip latitude), Brazil. The east-west components of the thermospheric temperatures obtained on 73 nights during the period from 1988 to 1992, primarily under quiet geomagnetic conditions, were...
متن کاملEnhancement of thermospheric mass density by soft electron precipitation
[1] Enhancements in F-region electron density and temperature and bottomside Pedersen conductivity caused by soft electron precipitation are shown to enhance the Joule heating per unit mass and the mass density of the thermosphere at F-region altitudes. The results are derived from the coupled magnetosphere-ionosphere-thermosphere model (CMIT) including two types of causally specified soft elec...
متن کاملSuperstatistics, thermodynamics, and temperature variations
A thermodynamic-like formalism is developed for superstatistical systems based on conditional entropies. This theory takes into account large-scale temperature variations for systems in nonequilibrium stationary states. Ordinary thermodynamics is recovered as a special case of the present theory, and corrections to it can be systematically evaluated. A generalization of Einstein’s relation for ...
متن کاملHigh-temperature differential emission measure and altitude variations in the temperature and density of solar flare coronal X-ray sources
The detailed knowledge of plasma heating and acceleration region properties presents a major observational challenge in solar flare physics. Using the Ramaty High Energy Solar Spectroscopic Imager (RHESSI), the high temperature differential emission measure, DEM(T ), and the energy-dependent spatial structure of solar flare coronal sources are studied quantitatively. The altitude of the coronal...
