Exploring the solar wind with a new view of small sun structures — ScienceDaily

Scientists have combined NASA data and cutting-edge image processing to gain new insight into the solar structures that create the Sun’s flow of high-speed solar wind, detailed in new research published today in The Astrophysical Journal. This first look at relatively small features, dubbed “plumelets,” could help scientists understand how and why disturbances form in […]

Plastic is blowing in the wind

As the plastic in our oceans breaks up into smaller and smaller bits without breaking down chemically, the resulting microplastics are becoming a serious ecological problem. A new study at the Weizmann Institute of Science reveals a troubling aspect of microplastics – defined as particles smaller than 5 mm across. They are swept up into […]

Polar climate affects trade wind strength in tropics — ScienceDaily

The impact of sea surface temperature variations in the tropical Pacific on global climate has long been recognized. For instance, the episodic warming of the tropical Pacific during El Niño events causes melt of sea ice in far-reaching parts of the Southern Ocean via its effect on the global atmospheric circulation. A new study, published […]

The Importance of Wind for the Fate of Volcanic Eruption Columns

The fate of volcanic eruptive columns (collapsing versus buoyant regime) is a complex issue in physical volcanology and represents a major hazard related to volcanoes. Column dynamics depends on a large number of variables, most of which are still poorly constrained. Michaud‐Dubuy et al. [2020] shed new light on some of those variables […]

Policy, not tech, spurred Danish dominance in wind energy — ScienceDaily

In emerging renewable energy industries, are producers’ decisions to shut down or upgrade aging equipment influenced more by technology improvements or government policies? It’s an important long-term question for policymakers seeking to increase renewable electricity production, cost-effectiveness and efficiency with limited budgets, says C.-Y. Cynthia Lin Lawell, associate professor in the Charles H. Dyson School […]

New Results Concerning Solar Wind Entry Into the Magnetosphere

Magnetospheric physicists seek to understand the nature of the solar wind’s interaction with the Earth’s magnetosphere. Some seek to predict environmental conditions hazardous to spacecraft operations within the magnetosphere, such as enhanced fluxes of energetic ions and electrons within the Van Allen radiation belts. Others focus on the fundamental processes that govern the […]
