  2. Increase of seismic events in XX century … … over the increase of seismic stations and equipment sensibility. So only the “atomic age” seismic data were used.

  3. SEISMICDATABASENEIC (1973-2003)291 thousands events, Ms > 3 IRIS(1964-2003)286thousands events, Ms > 4 NEIC IRIS

  4. The seismic intensity for various magnitudes (NEIC by SSA) versus solar activity (WN) • The intensity of the seismic process has low frequency variation nearly opposite to solar activity. • Seismic process responds to solar activity less than 10 % of intensity.

  5. Relative frequency of the origin of seismic swarm (P) in comparison with the solar activity (WN). The small-scale structure of the seismic events distribution is more sensitive to the solar activity.

  6. The time variations of persistency (H by R/S) as other structural parameter of the seismic events distribution Cor = 2H-1, 0< H <1, if H=0.5 => earthquake time distribution is Poisson. So the seismic event stream becomes more random with increasing of the solar activity. ? - Perhaps variations of the atmospheric pressure could be the intermediary between the solar activity and terrestrial seismicity (after Сытинский А.Д., 1987).

  7. The global 4-daily surface pressure (in Pa) NCEP/NCAR reanalysis data minus normal pressure (Ps)and their low-frequency filtering (Psf) (cut off 0.2 cpy). Left - The filtering data of upper figure without linear trend in comparison with the scaled solar activity. Right – The moving average (on 1 year interval) of the mean error (Std) of the filtering initial data of upper figure (cut off 1 cpy).

  8. The peak values of cross-correlation and corresponding time shifts of the atmospheric pressure for various regions and WN data. The irregular low-frequency variations are revealed in global and regional atmospheric surface pressure as well as in the amplitudes of noisy (high-frequency) component of the baric fields. These variations are close to the sun cycle butdo not give convincing arguments to consider the atmosphere as the transfer mechanism between solar activity and terrestrial seismicity.

  9. The another way is to determine the solar conditioned global distribution of various atmospheric parameters (sea level pressure, sea surface temperature and surface wind 72*144 = 10368 points on the globe) Cross-correlation(CC) WNand SLP dSLP

  10. Solar activity on the rise recession dSLP SLP

  11. Cross-correlationSSNand SST dSST There is common regions (mainly in oceans) where solar activity acts more effective. What kind of atmospheric processes are responsiblefor that?

  12. Tropical cyclons (TC) trackswww.csc.noaa.gov/hurrican_tracks(v, λ, φfor each hours from 1980) and dSLP Probably solar activity acts on the cyclogenesis. To test this assumption the research of TC evolution in magnetic storm was made. (see for “CATRIN” - К.Г.Иванов, 2005, Геомагнетизм и Аэрономия, т. 46, №5.)

  13. Ар–index (swdcwww.kugi.kyoto-u.ac.jp) The local maximum of Ap after smoothing (ωс> 1cpd) and pulse discrimination (<30)

  14. Dynamics of cumulative intencity of North-Atlantic and North-East Pacific TC relative to the moments of geomagnetic disturbance (±12 days from each local max of Ар) It is obvious that TC “avoids” geomagnetic stormsinNorth-Atlantic and indifferent to Ap inNorth-EastPacific .

  15. Cosmic IR images of cloudiness (each 6 h) and TC tracks

  16. The distribution of all (without discrimination) standardized Арrelative to the center of TC

  17. The time distribution of origin TC relative to the nearest maximum ofАр North-East Pacific North Atlantic

  18. Comparison of cyclons-day and seismicity days
