Definition of magnetic storm in US English:

magnetic storm


  • A disturbance of the magnetic field of the earth (or other celestial body).

    • ‘The magnetic storms are too severe to get any closer for the Probes and they cannot relay any clear photos back without having static wiping out the pixels.’
    • ‘Severe solar weather is often heralded by dramatic auroral displays, northern and southern lights, and magnetic storms that occasionally affect satellites, radio communications and power systems.’
    • ‘The information is important because of the potentially destructive effects of magnetic storms caused when the earth is hit by a surge of solar particles.’
    • ‘Stewart collected magnetic field measurements from several observatories but particularly from Sabine, who had concluded seven years earlier that the pattern of magnetic storms around Earth tracked closely with the sunspot cycle.’
    • ‘In the northeastern United States, a manufacturer of computer microchips shut down operations because the magnetic storm was disturbing sensitive instruments.’
    • ‘The transient radiation is mainly composed of protons and cosmic rays that constantly stream through space and are enhanced during the magnetic storms on the Sun known as ‘solar flares’.’
    • ‘Finally, Birkeland's theory of electron beams failed to account for the occurrence of magnetic storms close to Earth's equator.’
    • ‘In scientific circles where solar flares, magnetic storms and other unique solar events are discussed, the occurrences of September 1-2, 1859, are the star stuff of legend.’
    • ‘It is rare for the aurora borealis to be seen so spectacularly in this latitude, but the unusual sunspot activity, including magnetic storms, triggered a splendid display, which had been forecast by meteorologists.’
    • ‘According to measurements from spacecraft and ground observatories, a magnetic storm was just beginning to wane when a tremendous shock wave from the Sun arrived on May 4.’
    • ‘Severe solar weather is often heralded by dramatic auroral displays, but magnetic storms are occasionally harmful, potentially affecting satellites, radio communications and power systems.’
    • ‘A century after Carrington and Loomis dissected the great storm of 1859, the link between solar storms, magnetic storms, and man-made technology was obvious, if not well understood.’
    • ‘Together with Cluster, a group of four satellites launched in 2000, Double Star will be at the disposal of a group of Sino-European researchers who hope to discover more about what happens inside magnetic storms high above the atmosphere.’
    • ‘After he published his results, Edward Sabine and other scientists compared the rise and fall of sunspot numbers with the frequency of magnetic storms around Earth.’
    • ‘Suddenly, scientists around the world became interested in the sunspot cycle, reconstructing older records and comparing the changes in sunspot numbers with the number of magnetic storms detected on Earth.’
    • ‘The unexpected result resolves a forty-year-old debate as to how the safe zone is formed, and it illuminates how the region is cleared after it is filled with radiation during magnetic storms.’
    • ‘These immense clouds of material can cause large magnetic storms in the Earth's magnetosphere and upper atmosphere.’
    • ‘Some of these phenomena are spectacularly beautiful, such as the polar aurorae, but others, like the magnetic storms, can have serious effects on human activities - from power cuts to damaged satellites and communication breakdowns.’
    • ‘Many operators were expected to put their satellites into a ‘hibernate’ mode when the magnetic storm was at its height.’
    • ‘Forecasters are warning the power companies to brace for a wicked magnetic storm, which likely means that many cities along the East Coast will be forced to endure preventative rolling blackouts, disrupting commerce for the day.’
