“…Calisto et al [] and Rozanov et al [] found in their chemistry‐climate models that galactic cosmic rays (GCR) cause ozone loss in the polar lower stratosphere and modulate troposheric temperatures during winter. Veretenenko et al [] also linked long‐term variations in the North Atlantic surface air pressure to the cosmic rays. Mironova et al [] recently found an association between energetic electron precipitation and the vorticity of winter storms on the day‐to‐day time scale, which suggests a much faster mechanism than ozone destruction, possibly by the modulation of the global electric circuit [ Tinsley , ].…”

Spatial distribution of Northern Hemisphere winter temperatures during different phases of the solar cycle

Several recent studies have found variability in the Northern Hemisphere winter climate related to different parameters of solar activity. While these results consistently indicate some kind of solar modulation of tropospheric and stratospheric circulation and surface temperature, opinions on the exact mechanism and the solar driver differ. Proposed drivers include, e.g., total solar irradiance (TSI), solar UV radiation, galactic cosmic rays, and magnetospheric energetic particles. While some of these drivers are difficult to distinguish because of their closely similar variation over the solar cycle, other suggested drivers have clear differences in their solar cycle evolution. For example, geomagnetic activity and magnetospheric particle fluxes peak in the declining phase of the sunspot cycle, in difference to TSI and UV radiation which more closely follow sunspots. Using 13 solar cycles (1869-2009), we study winter surface temperatures and North Atlantic oscillation (NAO) during four different phases of the sunspot cycle: minimum, ascending, maximum, and declining phase. We find significant differences in the temperature patterns between the four cycle phases, which indicates a solar cycle modulation of winter surface temperatures. However, the clearest pattern of the temperature anomalies is not found during sunspot maximum or minimum, but during the declining phase, when the temperature pattern closely resembles the pattern found during positive NAO. Moreover, we find the same pattern during the low sunspot activity cycles of 100 years ago, suggesting that the pattern is largely independent of the overall level of solar activity.

“…Consequently, a weak 22‐year solar radiance variation has been found to excite a significant spectral peak, with a ~70 year period in global mean surface air temperature (Drijfhout et al , 1999). In the North Atlantic (45–65°N), a ~80 year periodicity has been detected in solar/geomagnetic activity and the intensity of cosmic rays in the cold months of the year (Veretenenko et al , 2005). The incidence of external cosmic ray penetration to the lower atmosphere is also the inverse of the sunspot cycle, so there is a lot of research required to disentangle what appears to be a complex non‐linear system, since cosmic rays could also accelerate nucleation through the process of electron bombardment (Svensmark and Calder, 2007).…”

“…The SOI‐solar association has been investigated recently due to increasing interest in the relationship between the Sun's cycles and climate (Drijfhout et al , 1999; De Jager, 2005; Veretenenko et al , 2005; Weng, 2005). The attraction of a solar application is that it offers the potential for the long‐range prediction of SOI behaviour and associated rainfall variations, since quasi‐periodicity in solar activity results in an expected cycle of situations and phases (for example, polar reversals and sunspot minima) that are not random events.…”

Exploratory Analysis of Similarities in Solar Cycle Magnetic Phases with Southern Oscillation Index Fluctuations in Eastern Australia

There is growing interest in the role that the Sun's magnetic field has on weather and climatic parameters, particularly the ~11 year sunspot (Schwab) cycle, the ~22 yr magnetic field (Hale) cycle and the ~88 yr (Gleissberg) cycle. These cycles and the derivative harmonics are part of the peculiar periodic behaviour of the solar magnetic field. Using data from 1876 to the present, the exploratory analysis suggests that when the Sun's South Pole is positive in the Hale Cycle, the likelihood of strongly positive and negative Southern Oscillation Index (SOI) values increase after certain phases in the cyclic ~22 yr solar magnetic field. The SOI is also shown to track the pairing of sunspot cycles in ~88 yr periods. This coupling of odd cycles, 23–15, 21–13 and 19–11, produces an apparently close charting in positive and negative SOI fluctuations for each grouping. This Gleissberg effect is also apparent for the southern hemisphere rainfall anomaly. Over the last decade, the SOI and rainfall fluctuations have been tracking similar values to that recorded in Cycle 15 (1914–1924). This discovery has important implications for future drought predictions in Australia and in countries in the northern and southern hemispheres which have been shown to be influenced by the sunspot cycle. Further, it provides a benchmark for long‐term SOI behaviour.

“…The latitude effect of cosmic radiation intensity has been analyzed by several authors using the techniques available at the time of their reports [23][24][25]. Recently, Veretenenko et al [26] investigated the long-term variation of surface pressure in the North Atlantic, and their association with galactic cosmic rays. Measurements at sea level of cosmic rays intensity were carried out between Tokyo Bay and Indian Ocean using a NaI (Tl) scintillation detector installed on the deck of a vessel [27].…”
