Post-eruptive loops in the wake of a solar flare, image taken by the TRACE satellite (photo by NASA). In solar physics, a solar particle event (SPE), also known as a solar energetic particle event or solar radiation storm, [a] [1] is a solar phenomenon which occurs when particles emitted by the Sun, mostly protons, become accelerated either in the Sun's atmosphere during a solar flare or in ...
Marine cloud brightening proposes to generate a similar effect using benign material (e.g. sea salt) delivered to clouds that are most susceptible to these effects (marine stratocumulus). Most clouds are quite reflective, redirecting incoming solar radiation back into space. Increasing clouds' albedo would increase the portion of incoming solar ...
Scientists subsequently tested the hypothesis. Some concluded that there was no evidence supporting the hypothesis. [3] Others found evidence suggesting that increased sea surface temperature (SST) in the tropics did indeed reduce cirrus clouds but found that the effect was nonetheless a positive climate feedback rather than the negative feedback that Lindzen had hypothesized.
Variations in the ultraviolet component. The UV component varies by more than the total, so if UV were for some (as yet unknown) reason to have a disproportionate effect, this might explain a larger solar signal. Effects mediated by changes in galactic cosmic rays (which are affected by the solar wind) such as changes in cloud cover.
Ground level enhancements are usually accompanied by a solar radiation storm. GLE occurrence rate was 29% for S2 or larger storms, 36% for S3 or larger, and 40% for S4 when correlated with the S-scale (related to the number of >10MeV protons measured at geosynchronous orbit). [2] GLEs are uncommon.
An unusually strong solar storm hitting Earth produced stunning displays of color in the skies across the Northern Hemisphere early Saturday, with no immediate reports of disruptions to power and ...
A severe geomagnetic storm could disrupt communications and bring northern lights to parts of California, according to a warning from the National Oceanic and Atmospheric Administration.
Sea ice reflects 50% to 70% of the incoming solar radiation back into space. Only 6% of incoming solar energy is reflected by the ocean. [67] As the climate warms, the area covered by snow or sea ice decreases. After sea ice melts, more energy is absorbed by the ocean, so it warms up.
