Modeling subsolar thermospheric waves during a solar flare and penetration electric fields
Abstract Thermospheric waves occurring around the time of the 14 July 2000 solar flare were investigated using the Global Ionosphere and Thermosphere Model. The simulation results showed that extensive acoustic and gravity waves were excited by the solar flare in the subsolar region. The subsolar buoyancy period at 400 km altitude was approximately 16 min. Gravity waves with frequencies lower t...
متن کاملCarrington Flare of 1859 as a Prototypical Worst-Case Solar Energetic Particle Event
Recent analyses of ice core samples indicate that the Carrington flare of 1859 was the largest event observed in the past 500 years. These ice core data yield estimates of the proton fluence for energies greater than 30 MeV, but provide no other spectrum information. Assuming that the proton energy distribution for such an event is similar to that measured for other recent, large events, total ...
متن کاملDielectrophoretic effect of nonuniform electric fields on the protoplast cell
In recent years, dielectrophoresis based microfluidics systems have been used to manipulate colloids, inert particles, and biological microparticles, such as red blood cells, white blood cells, platelets, cancer cells, bacteria, yeast, microorganisms, proteins, DNA, etc. In the current study the governing electric potential equations have been solved in the presence of cell for the purpose of ...
متن کاملMeasurements and models of electric fields in the in vivo human brain during transcranial electric stimulation
Transcranial electric stimulation aims to stimulate the brain by applying weak electrical currents at the scalp. However, the magnitude and spatial distribution of electric fields in the human brain are unknown. We measured electric potentials intracranially in ten epilepsy patients and estimated electric fields across the entire brain by leveraging calibrated current-flow models. When stimulat...
متن کاملLongitudinal variation of the E-region electric fields caused by atmospheric tides
[1] Polarization electric fields created by the Eand Fregion dynamos cause the uplift of F-region plasma. The subsequent redistribution of that plasma along the magnetic field lines creates the equatorial ionospheric anomaly (EIA). Observations of the post-sunset EIA made by the IMAGE and TIMED satellites are compared here with CHAMP, Ørsted and SAC-C observations of the noontime equatorial ele...
