6 Polar Caps
The permanent polar caps of Mars constitute the largest known reservoirs of H2O on the planet. The permanent caps are distinguished from the seasonal...

Polar Photospheric Magnetic Field Evolution and Global Flux Transport
The Sun’s polar magnetic fields are of paramount importance in structuring the heliosphere and in seeding the activity cycle, but they are difficult...

Io’s polar volcanic thermal emission indicative of magma ocean and shallow tidal heating models
The distribution of Io’s volcanic activity probably reflects the position and magnitude of internal tidal heating, but full mapping of the moon has...

The Polar Field Reversal Process over Five Solar Cycles
We examine the process during which the solar magnetic field reverses polarity around each solar maximum. We use the McIntosh Archive (McA) of solar...

Influence of Solar Activity and Galactic Cosmic Ray Variations on Trajectories of Extratropical Cyclones in the North Atlantic
AbstractWe investigated long-term changes of the main trajectories of extratropical cyclones in the North Atlantic. It was found that the average...

Morning Geomagnetic Bays at Polar Latitudes and Their Magnetospheric Sources
AbstractA study is performed of morning polar bay-like magnetic disturbances observed at latitudes above 70° MLAT with no simultaneous geomagnetic...

The Geochemical Effect of Impact Processing of Polar Regolith on the Moon
AbstractThe paper considers the geochemical effects of impact processing of the polar regolith of the Moon. It contains an admixture of water ice,...

Vorticity and divergence at scales down to 200 km within and around the polar cyclones of Jupiter
Since 2017 the Juno spacecraft has observed a cyclone at the north pole of Jupiter surrounded by eight smaller cyclones arranged in a polygonal...

Impact Crater with Traces of Tectonic Deformation in the South Polar Region of the Moon
Abstract —The work examines the structure of a crater with a diameter of 34 km, located on the mainland in the marginal zone of the south polar region...

Two New Methods for Counting and Tracking the Evolution of Polar Faculae
Polar faculae are the footpoints of magnetic-field lines near the Sun’s poles that are seen as bright regions along the edges of granules. The time...

Numerical Modeling of the Origination of Polar Lows in the High-Latitude Atmosphere
AbstractResults are presented from numerically modeling the initial stage of the origination of polar lows in the troposphere in the vicinity of an...

Long-Term Variability of North Atlantic Storm Tracks: Possible Influence of Solar Activity and Cosmic Ray Variations
In this work we study long-term variability of the main directions of extratropical cyclone movement (storm tracks) in the North Atlantic basing on...

Migration of Water Molecules in the Permanently Shaded Areas of Polar Areas of Mercury
Radar observations of the surface of Mercury had revealed areas with bright reflective properties in both polar regions of the planet. It was...

Surface topographic impact of subglacial water beneath the south polar ice cap of Mars
Bright radar reflections observed in the Ultimi Scopuli region of Mars’ south polar layered deposits
1 –3 by the Mars Advanced Radar for Subsurface and...

Interplanetary energetic electrons observed in Earth’s polar cusp/cap/lobes
The Earth’s polar cusp, cap and lobes are the important boundaries to transport the plasma and energy from the interplanetary medium to terrestrial...

Seasonal Features of the Spatial Distribution of Atmospheric Gravity Waves in the Earth’s Polar Thermosphere
Abstract—The features of the spatial distribution of atmospheric gravity waves (AGW) in the polar thermosphere of the Earth are investigated. The...

Latitude Variations in Primary and Secondary Polar Crown Polarity Inversion Lines and Polar Coronal Hole Boundaries over Five Solar Cycles
We undertake a five solar-cycle (SC 19 - 23) ≈55-year (December 1954 to August 2009) study of the high latitude polarity inversion lines (PILs) using...

Sun-synchronous orbital dust ring to reduce climate change at the polar caps
As a geoengineering strategy to attenuate the solar insolation and offset the impacts of global warming at the polar regions, this study proposes a...
