Energy partition in magnetic reconnection in Earth's magnetotail.
The partition of energy flux in magnetic reconnection is examined experimentally using Cluster satellite observations of collisionless reconnection in Earth's magnetotail. In this plasma regime, the dominant component of the energy flux is ion enthalpy flux, with smaller contributions from the electron enthalpy and heat flux and the ion kinetic energy flux. However, the Poynting flux is not neg...
متن کاملEnergy release and conversion by reconnection in the magnetotail
Magnetic reconnection is the crucial process in the release of magnetic energy previously stored in the magnetotail in association with substorms. However, energy transfer and dissipation in the vicinity of the reconnection site is only a minor part of the energy conversion. We discuss the energy release, transport, and conversion based on largescale resistive MHD simulations of magnetotail dyn...
متن کاملThree-species collisionless reconnection: effect of O+ on magnetotail reconnection.
The nature of collisionless reconnection in a three-species plasma composed of a heavy species, protons, and electrons is examined. In addition to the usual two length scales present in two-species reconnection, there are two additional larger length scales in the system: one associated with a "heavy whistler" which produces a large scale quadrupolar out-of-plane magnetic field, and one associa...
متن کاملContribution of magnetotail reconnection to the cross‐polar cap electric potential drop
[1] Since the work of Dungey (1961), the global circulation pattern with two (dayside and nightside) reconnection regions has become a classic concept. However, the contributions of dayside and nightside sources to the cross‐polar cap potential (PCP) are not fully understood, particularly, the relative role and specifics of the nightside source are poorly investigated both in quantitative and q...
متن کاملMicrostructure of Magnetic Reconnection in Earth's Magnetotail
A recent study of magnetic reconnectiori in the earth's magnetotail dentified five events in which a pulse of heated electrons appeared near the end of an interval of fast tailward plasma flow. Further investigation of these events has revealed the following information on their microstructure' (1) Measurements of the electron Velocity distribution show that the temperature rise can be characte...
