Present Understanding

The average characteristics of year-to-year variability of Galactic cosmic ray (GCR) flux measured in one mid-latitude neutron monitor stations (Newark) and high latitude station (Apatity) have been studied under different planetary disturbance (Kp) conditions. The year-to-year variability which oscillates in response to solar cycle was analyzed using Fourier technique and the amplitude of variation was obtained using data for 1980–2005. There is a noticeable trend in the difference between the amplitudes of the year-to-year variation of the two stations. The difference is highest during low Kp conditions and lowest during high Kp condition. There is generally lesser association of GCR with solar wind (SW) flow pressure and density as the Kp index increases. Similar feature is observed with the interplanetary magnetic field IMF (total). These observations have important implications for our present understanding of the effect of solar activity to variability in GCR flux.

Present Understanding

Spacecraft observations of the Earth’s magnetosphere have revealed the presence of a complex spatially structured plasma and field environment, which undergoes significant variations on time-scales from minutes to years. Magnetospheric plasma originates in the solar wind and the ionosphere, and the principal transport process is a twin-vortical flow driven by coupling to the solar wind. We review present understanding of the coupling process and some consequences which follow.
