"Solar max," as scientists call it, is an 11-year cycle where the sun's magnetic field reverses polarity, typically spawning sunspots, flares, auroras and geomagnetic storms that, if large enough, can disrupt satellites and fry power grids on Earth. Over a period of about two years, "the...
The effect of the 11-year solar cycle on the response of the stratospheric geopotential height and temperature fields at 10 and 30 hPa in winter to solar activity oscillations with periods related to the period of the Sun's rotation (27.2 days) is discussed, applying methods of statistical ...
Image of sun courtesy of NASA. Streaming into the solar system at nearly the speed of light, galactic cosmic rays (GCRs) are a high-energy mix of protons, electrons, and atomic nuclei. As they pass into reach of the outflowing solar wind, the propagation of GCRs is inhibited. Galactic ...
For the past eighteen months, high latitude (20°–40°) sunspots have begun to appear in increasing numbers, giving the characteristic overlap seen at this epoch of the 11-year cycle with the decreasing old-cycle spots in equatorial latitudes (0°–10°). The routine observations of the ...
The Signal of the 11-Year Sunspot Cycle in the Regions around Japan We outline the correlations between the height of the constant pressure levels in the lower stratosphere in the Japanese region and the 11-year solar cycle... K Labitzke,HV Loon - 《Journal of the Meteorological Society of...
11-year solar cycle in the North Atlantic Oscillation in winter, which thereby raises the possibility of using the solar cycle to predict the circulation years in advance. Here we present evidence that contradicts this claim. First, we show the absence of a solar signal in the North Atlantic ...
Solar activity rises and falls with an 11-year cycle that affects modern life in many ways. Increased solar activity includes increases in extreme ultraviolet and X-ray emissions from the Sun that produce dramatic effects in Earth’s upper atmosphere. The associated atmospheric heating increases both...
This may be partly a direct effect in this layer, because of more absorber (ozone) and more ultraviolet radiation from the sun in the peaks of the 11-year solar cycle. However, it is more likely to be mainly an indirect dynamical consequence of UV absorption by ozone in the middle and ...
As Voyager 2 moves further into the heliosheath, the region of subsonic solar wind plasma in between the termination shock and the heliopause, it has observed an increase of the magnetic field strength to large values, all while maintaining magnetic flux conservation. Dr. Burlaga will present the...
The modulation of the relationship between the Arctic Oscillation (AO) and the East Asian winter climate by the 11-year solar cycle was investigated. During winters with high solar activity (HS), robust warming appeared in northern Asia in a positive AO phase. This result corresponded to an en...
