Sentences with word «magnetopause»

«THEMIS's elliptical orbits achieved over one thousand magnetopause crossings and provided unprecedented observations.

Cassini UVIS observations revealed recently the presence of small - scale structures in the dayside main auroral emissions indicative of magnetopause Kelvin - Helmholtz instabilities, which are key elements of the solar wind - magnetosphere viscous interaction (Grodent et al. 2011).

The magnitude of electric field in the atmosphere is proportional to the nearness of magnetopause to the Earth..

«And this is significant because whenever the edge of Earth's magnetosphere, the magnetopause, gets rattled it will create waves that propagate everywhere in the magnetosphere, which in turn can energize or de-energize the particles in the radiation belts.»

Using data from NASA's Time History of Events and Macroscale Interactions during Substorms (THEMIS) mission, Raeder and his Ph.D. student Shiva Kavosi (lead author) found that Kelvin - Helmholtz waves actually occur 20 percent of the time at the magnetopause and can change the energy levels of our planet's radiation belts.

«Previously, people thought Kelvin - Helmholtz waves at the magnetopause would be rare, but we found it happens all the time.»

Thus reconnection at Earth's magnetopause can cause destructive space weather that can damage satellites, threaten the health of astronauts, and disrupt communications and energy grids on the surface.

In 6 months they made 4000 passes through the magnetopause.

As the MMS team reports today in Science, instead of the turbulent swirling of electrons that some theorists had predicted, researchers found that the electrons moved in a more concerted way, meandering back and forth across the magnetopause.

That phenomenon occurs where opposing magnetic fields from different sources meet, such as at the magnetopause, the boundary in space at which the sun's field pushes against the Earth's.

Earth's magnetopause «is the only place you can do this,» Burch says.

Recently, it was suggested that only a limited fraction of the magnetopause surface could become open (Masters et al. 2012).

Moreover, recent studies indicated that reconnection has a less important role at Saturn than at the Earth, in large - scale transport near the subsolar region of the magnetopause (Lai et al. 2012).

Earth's magnetic field points north at the magnetopause.

The outer boundary of Earth's magnetosphere is called the magnetopause — that's where Earth's magnetic field bumps into the Sun's and fends off the solar wind.

If the Sun's magnetic field tilts south near the magnetopause, it can partially cancel Earth's magnetic field at the point of contact.

This explains the presence of reservoirs of high - energy particles under these areas in the magnetopause but for some time scientists remained puzzled as to why these reservoirs are also found in areas where the two magnetic fields at the magnetopause are aligned and should therefore create an impenetrable barrier.

Auroras are a consequence of the solar wind penetrating the magnetopause when magnetic reconnection occurs.

The fluctuations mostly propagated tailward, passing along the magnetopause.
