A space hurricane over the Earth’s polar ionosphere - Nature
2021年2月22日 · Here, we present an observation of a long-lasting, large and energetic space hurricane in the northern polar ionosphere that deposited solar wind/ magnetosphere energy and momentum into the...
Ionosphere - Wikipedia
The ionosphere is a shell of electrons and electrically charged atoms and molecules that surrounds the Earth, [18] stretching from a height of about 50 km (30 mi) to more than 1,000 km (600 mi). It exists primarily due to ultraviolet radiation from the Sun.

2014年1月1日 · The polar caps of the ionosphere are the areas poleward of the auroral oval in the Northern and Southern Hemispheres. These areas have a nearly vertical magnetic field.
Ionosphere Dynamics and Applications | Geophysical …
2021年3月24日 · Ionosphere Dynamics and Applications provides a comprehensive overview of historic developments, recent advances, and future directions in ionospheric research. Volume highlights include: Behavior of the ionosphere in different regions from the poles to the equator; Distinct characteristics of the high-, mid-, and low-latitude ionosphere
The polar ionosphere - ScienceDirect
2004年1月1日 · We will now show polar 630 nm airglow measurements from the continuous meridian scans across the whole polar cap as a proxy to polar cap F-region electron densities, to discuss polar cap ionospheric variability.
Transient Response of Polar‐Cusp Ionosphere to an …
2023年3月15日 · We study the transient response of the polar cusp ionosphere to external solar wind driving by examining the cusp ionospheric variations driven by an IP shock. We use observations from the Antarctic ZHO station and SuperDARN radars deployed in the southern hemisphere to analyze the effect and impact of the IP shock.
Earth’s ambipolar electrostatic field and its role in ion escape to ...
2024年8月28日 · The ambipolar field of Earth controls the structure of the polar ionosphere and boosts its scale height by 271%, physically driving the polar wind and acting as the source of the magnetospheric...
Polar ionospheric currents and high temporal resolution …
2023年8月16日 · Estimating high resolution models of the Earth’s core magnetic field and its time variation in the polar regions requires that one can adequately account for magnetic signals produced by polar ionospheric currents, which vary on a wide range of time and length scales.
Structured Storm-Time Polar Ionosphere and Its Drivers
2021年3月23日 · This chapter provides a review of the most recent progress in understanding polar ionosphere (including both high- and subauroral latitudes in this chapter) variability and its drivers. It also aims to point out future directions for this topic.
Climatology of polar ionospheric density profile in comparison …
2020年12月1日 · In this review, we present the climatology of the polar ionospheric density not only in the F-region but also in the E-region and topside ionosphere, in comparison with the mid-latitude ionosphere, using long-term incoherent scatter radar (ISR) observations at Millstone Hill, Tromsø, and Svalbard.
