Adversarial super-resolution of climatological wind and solar data

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Global climate simulations are typically unable to resolve wind and solar data at a resolution sufficient for renewable energy resource assessment in different climate scenarios.

Tenuous solar winds: Insights on solar wind–magnetosphere interactions

Journal of Atmospheric and Solar-Terrestrial Physics, 2008
Abstract During solar cycle 23 quasi-dropouts of the solar wind (density 1 cm - 3 ) were observed. These tenuous winds allow us to probe properties of the magnetosphere and its coupling to the solar wind which would otherwise be obscured by the effect of high density.

Short, large-amplitude speed enhancements in the near-Sunfast solar wind

, 2018
We report the presence of intermittent, short discrete enhancements in plasma speed in the nearSun high-speed solar wind. Lasting tens of seconds to minutes in spacecraft measurements at 0.3 au, speeds inside these enhancements can reach 1000 km s−1 ...

Material Challenges and Alloy Selection for Particle/s‐CO2 Heat Exchangers in Concentrated Solar Power Systems

Advanced Engineering Materials, EarlyView.
Combining supercritical CO2 (s‐CO2) cycles with particle‐based heat transfer media holds great potential in concentrated solar power plants but poses enormous material challenges. The particle/s‐CO2 heat exchanger must withstand extreme conditions, including high temperatures, pressures, CO2 corrosion, and erosion.

Parker Solar Probe Observations of High Plasma β Solar Wind from the Streamer Belt

The Astrophysical Journal Supplement Series, 2023
In general, slow solar wind from the streamer belt forms a high plasma β equatorial plasma sheet around the heliospheric current sheet (HCS) crossing, namely, the heliospheric plasma sheet (HPS).

Dependence of Intensities of Major Geomagnetic Storms (Dst $\le$ -100 nT) on Associated Solar Wind Parameters [PDF]

, 2020
A geomagnetic storm is the result of sustained interaction between solar wind with a southward magnetic field and the magnetosphere. To investigate the influence of various solar wind parameters on the intensity of major geomagnetic storm, 67 major geomagnetic storms that occurred between 1998 and 2006 were used to calculate the correlation ...

Verification of high‐speed solar wind stream forecasts using operational solar wind models [PDF]

, 2016
High‐speed solar wind streams emanating from coronal holes are frequently impinging on the Earth's magnetosphere causing recurrent, medium‐level geomagnetic storm activity. Modeling high‐speed solar wind streams is thus an essential element of successful

Full-Sun observations for identifying the source of the slow solar wind [PDF]

Nature Communications, 2015
Fast (>700 km s−1) and slow (~400 km s−1) winds stream from the Sun, permeate the heliosphere and influence the near-Earth environment. While the fast wind is known to emanate primarily from polar coronal holes, the source of the slow wind remains ...

Solar-Wind Structures That Are Not Destroyed by the Action of Solar-Wind Turbulence [PDF]

Frontiers in Astronomy and Space Sciences, 2021
If MHD turbulence is a dominant process acting in the solar wind between the Sun and 1 AU, then the destruction and regeneration of structure in the solar-wind plasma is expected. Six types of solar-wind structure at 1 AU that are not destroyed by turbulence are examined: 1) corotating-interaction-region stream interfaces, 2) periodic density ...
