Sentence examples for northern cusp from inspiring English sources

When it is positive, the northern cusp moves to later local times.

The reversal of B x associated with a simultaneous southward turning of B z is a favorable condition for the reconnection in the northern cusp region.

This localized large impulse in the northern cusp region near noon would be produced by the reconnection associated with a sudden IMF rotation.

Coco et al. (2008) used SuperDARN, spacecraft and ground magnetometer data to study the magnetosphere compressed by an interplanetary shock during an IMF By-dominated period, they found that at very high latitudes above the northern cusp and in the morning sector, enhanced sunward convection fluxes appear with a signature typical for northward Bz-dominated lobe reconnection.

The observations made with the ISTP/POLAR spacecraft were mostly obtained during geomagnetically non-storm times in April 2001 when the spacecraft orbit allowed northern cusp encounters with low trajectory angle between the spacecraft velocity vector and the overall cusp magnetic field orientation.

Cassini crossed the northern cusp around noon local time along a poleward trajectory.

We also found that what appears to be the interior of the northern polar magnetic cusp region can be rather turbulent both in the local magnetic field direction and in the energetic charged particle kinetic flow characteristics.

The launch of the POLAR spacecraft has allowed similar exploration of the high altitude polar cusp in the northern hemisphere.

Concerning the formation of a cold/dense plasma sheet in the tail center, double cusp reconnection under northern interplanetary magnetic field (IMF) conditions and subsequent slow penetration of mass-loaded, closed flux tubes from the flanks into the central tail sector is a much longer process, requiring as much as ~8 h to transpire (Terasawa et al. 1997; Wang et al. 2010).

Before the SI onset at ~09 22 UT, Fig. 4 shows that the dim green aurora in ray or weak patchy structure can be seen in the northern portion of the FOV, which signifies that the cusp auroral emission was steady before ~09 22 UT, namely intervals prior to the magnetospheric disturbance caused by the shock impact.

As the IMF By component becomes more negative, the cusp moves to earlier local times in the northern hemisphere.
