Sentences with phrase «ray modulation»

An important parameter for cosmic ray modulation is the solar dipole moment [DM] at minimum.

I also mentioned previously the possibility of cosmic ray modulation, via velocity induced changes in the Lorentz force which deflects them, affecting the Earth's climate (though, I still haven't made any calculations to see whether that idea holds any water).

The reversal of magnetic field strength from one solar hemisphere to the other may have significant effects on cosmic ray modulation, for example.

Here is one from Brazil Evidence for cosmic ray modulation in temperature records from the South Atlantic Magnetic Anomaly region (Annales Geophysicae, Volume 31, Issue 10, pp. 1833 - 1841, October 2013)- E. Frigo et al..

I am concerned about the apparent lack of correlation between the shortwave reflections and CRF as measured by the neutron counter (figure 6 on my DRAFT copy of «Cosmic rays modulation of the cloud effects on the radiative flux in the Southern Hemisphere Magnetic Anomaly region»).

Although observational limitations restrict the maximum angle to be 70 ° (Suess et al. 1993), this does not affect the use of this model's reconstructions for the study of GCRs heliospheric modulation, since convective - diffusive processes are the main contributors to cosmic rays modulation for tilt angle values greater than 50 ° (Lopate & Simpson 1991; Potgieter & Le Roux 1992; Cliver et al. 2013).

Modulation is only important for cosmic ray particles with energies below about 50 GeV.

I mean since there is no clear trend (upward or downward) in cosmic ray flux over the period we've been able to measure them directly; and since we do not see a significant difference in climate over the 11 year solar cycle between Solar Max and Solar Min (and this modulation is much larger than the one Svensmark is talking about); and since it is not clear how important the ionization from GCR is in cloud formation; and since the anthropogenic ghg mechanism does just fine reproducing the data, exactly how do you foresee implementing this «effect»?

Similarly to the solar magnetic modulation, high geomagnetic field intensity decreases the flux of galactic cosmic rays and radionuclide production rates and the opposite for low geomagnetic field intensity.
