Magnetic Coupling in the Quiet Solar Atmosphere

, 2009
Three kinds of magnetic couplings in the quiet solar atmosphere are highlighted and discussed, all fundamentally connected to the Lorentz force. First the coupling of the convecting and overshooting fluid in the surface layers of the Sun with the ...

Atmospheric Physics and Atmospheres of Solar-System Bodies [PDF]

, 2018
The physical principles governing the planetary atmospheres are briefly introduced in the first part of this chapter, moving from the examples of Solar System bodies. Namely, the concepts of collisional regime, balance equations, hydrostatic equilibrium and energy transport are outlined. Further discussion is also provided on the main drivers governing

The mechanism of temperature and pressure changes in the Earth's atmosphere during solar flares [PDF]

The effect of solar flares on the weather on Earth is examined. It is concluded that the processes which arise in the atmosphere are so intricate that a single calculation of solar activity is insufficient for long-range forecasting.

Overview of HLLV effluents in stratosphere and above [PDF]

, 1980
The injection of large quantities of rocket exhaust effluent into the upper atmosphere by the heavy lift launch vehicle (HLLV) of the solar power satellite system is discussed. The exhaust products considered are CO, CO2, H2O, H2, and NO.

Comparison of theoretical and observed Ca~{\sc ii}~8542 Stokes profiles in quiet regions at the centre of the solar disc

, 2018
Interpreting the Stokes profiles observed in quiet regions of the solar chromosphere is a challenging task. The Stokes Q and U profiles are dominated by the scattering polarisation and the Hanle effect, and these processes can only be correctly ...

Exploring the Dynamic Rotational Profile of the Hotter Solar Atmosphere: A Multiwavelength Approach Using SDO/AIA Data

The Astrophysical Journal
Understanding the global rotational profile of the solar atmosphere and its variation is fundamental to uncovering a comprehensive understanding of the dynamics of the solar magnetic field and the extent of coupling between different layers of the Sun ...

Variability of Solar Five-Minute Oscillations in the Corona as Observed by the Extreme Ultraviolet Spectrophotometer (ESP) on the Solar Dynamics Observatory Extreme Ultraviolet Variability Experiment (SDO/EVE)

, 2012
Solar five-minute oscillations have been detected in the power spectra of two six-day time intervals from soft X-ray measurements of the Sun observed as a star using the Extreme Ultraviolet Spectrophotometer (ESP) onboard the Solar Dynamics Observatory ...

Solar variability, weather, and climate [PDF]

Advances in the understanding of possible effects of solar variations on weather and climate are most likely to emerge by addressing the subject in terms of fundamental physical principles of atmospheric sciences and solar-terrestrial physis.

The Carrying Capacity of the Solar Wind: Applications to Ion Escape

The Astrophysical Journal
We present a physically motivated analytic framework for estimating solar wind mass-loading rates from ion sources using a simplified “particles in a box” (PIB) model.
