Sentences with phrase «activity changes these magnetic fields»

Not exact matches

The Sun's activity — including changes in the number of sunspots, levels of radiation and ejection of material - varies on an eleven - year cycle, driven by changes in its magnetic field.

It monitors changes in Earth's magnetic field, providing data that help NOAA and the U.S. Air Force track magnetic storms due to solar activity.

But mole rats that built nests within changing magnetic fields showed strong activity in a brain region called the superior colliculus, which collects spatial cues and directs orienting behavior.

After all, the implied changes in GCR flux are huge compared to what is expected from the gentle modulation of the Earth's magnetic field arising from recent solar activity changes (not that there's any trend in those that would explain recent warming).

The good news: The scientists argue that the minimum magnetic field strength will change depending on the M - dwarf's spectral type, as well as on stellar activity and stellar magnetic field strength changes.

Heliophysics encompasses cosmic rays and particle acceleration, space weather and radiation, dust and magnetic reconnection, solar activity and stellar cycles, aeronomy and space plasmas, magnetic fields and global change, and the interactions of the solar system with our galaxy.»

Solar» activity» encompasses changes in solar magnetic field strength, IMF, CRF, TSI, EUV, solar wind density and velocity, CMEs, proton events etc..

We show that the index commonly used for quantifying long - term changes in solar activity, the sunspot number, accounts for only one part of solar activity (William: Closed magnetic field) and using this index leads to the underestimation of the role of solar activity in the global warming in the recent decades.

Fluctuations in solar activity, including magnetic field - powered sunspots and solar flares, have been linked to past changes in climate, including, controversially, the Little Ice Age.

Your own 300 year long sunspot data (as well as those of Wang, Lean, and Sheeley) http://www.vukcevic.talktalk.net/TMC.htm also suggest that there is an (for some inconvenient) direct strong link between solar activity and the Earth's magnetic field change.

Long - term trends in the upper atmosphere - ionosphere are a complex problem due to simultaneous presence of several drivers of trends, which behave in a different way: increasing atmospheric concentration of greenhouse gases, mainly CO2, long - term changes of geomagnetic and solar activity, secular change of the Earth's main magnetic field, remarkable long - term changes of stratospheric ozone concentration, and very probably long - term changes of atmospheric dynamics, particularly of atmospheric wave activity (Lastovicka 2009; Qian et al. 2011; Lastovicka et al. 2012).

Whereas CO2 concentration is quasi-steadily increasing, other drivers change their trends with time even to opposite (solar and geomagnetic activity, stratospheric ozone), or change trends with location (Earth's main magnetic field), or with latitude (geomagnetic activity), or are largely unknown but probably unstable in space and time (atmospheric winds and waves).

Since these fields are close enough to react with eachother changes in the suns magnetic fiels must certainly have an effect on the Earth's tectonic activity.

Sunspots and other forms of solar activity are produced by magnetic fields, whose changes also affect the radiation that the Sun emits, including its distribution among shorter and longer wavelengths.

After all, the implied changes in GCR flux are huge compared to what is expected from the gentle modulation of the Earth's magnetic field arising from recent solar activity changes (not that there's any trend in those that would explain recent warming).
