North-South asymmetry

North-south asymmetry in Martian crater slopes

[1] The presence of an extensive ice-rich layer in the near subsurface of the Martian regolith could result in viscous creep responsible for softening of craters at middle and high latitudes. The temperature of ground ice will vary spatially within a crater owing to the effect of slope on the effective angle of insolation. The temperature at a particular latitude will also vary temporally owing...

North-South asymmetry in the ionosphere and seismic activity

[1] A retrospective study of the North-South asymmetry (NSA) during the solstices is made using the different geospace parameters in the North and South magnetic hemispheres. The NSA features are investigated using Total Electron Content, TEC, and Global Electron Content, GEC, produced from global ionospheric maps, GIM-TEC for 1999-2013, the Ionospheric Electron Content, IEC, measured by Topex-...

The North−south Asymmetry of Soft X- Ray Flare Index during Solar Cycles

In this paper the N−S asymmetry of the soft X-ray flare index (FISXR) during the solar cycles 21, 22 and 23 has been analyzed. The results show the existence of a real N−S asymmetry which is strengthened during solar minimum. The slope of the regression lines fitted to the daily values of asymmetry time series has been found to be negative in all the three cycles. The yearly asymmetry curve can...

Titan’s North–South Asymmetry from HST and Voyager Imaging: Comparison with Models and Ground-Based Photometry

Tomasko and Smith (1982). Examination of the Voyager 2 (V2) data in Smith et al. (1982) reported no significant New measurements of Titan’s hemispheric brightness asymvariation from V1 to V2, consistent with a seasonally varymetry from HST images from 260 to 1040 nm show that the contrast is strongest near 450 nm (blue) and, with the opposite ing asymmetry at a peak in the early 1980s (i.e., ne...
