Sentence examples for gradual events from inspiring English sources
Particles with energies greater than 10 MeV are observed within several hours after the occurrence of flares and CMEs in many gradual events.
Typical gradual events that resemble closely coronal composition are found with Fe charge state of ≈11 and impulsive events with high Fe abundance and charge states between 17 and 20.
The results suggest that for gradual events with both peaks, the ESP peak often dominates at 1 MeV energies and is dominant about half the time at 10 MeV.
It has recently been proposed that residual energetic ions from preceding impulsive solar energetic particle (SEP) events may contribute to the source population for the larger gradual events accelerated by CME-driven shocks (Mason et al., 1999).
In the gradual events main energization occurs close to the Sun at low Mach numbers; significant interplanetary enhancement of energetic ion fluxes requires a narrow scale length in the propagating shock.
One of the selection criteria of quiet-time periods is to demand that H/He < 10 provided that periods with noticeable contribution of remnants of gradual events have been excluded from consideration.
The Holocaust was a gradual event, going back to official anti-Semitic policies and pogroms, but accelerating with anti-Jewish policies and actions in 1932 and 1933.
Thus, when the usual classification refers to a gradual event, this fails to distinguish between particle populations of three distinct acceleration histories.
The coexistence of three different rodent metacommunities during the early Vallesian in the southern province as well as the prolonged persistence and gradual changes in the ecological structure of metacommunity B in the northern province appear to reinforce this interpretation of the Vallesian Crisis as a gradual event.
We discuss the implications of these observations for the origin of particles accelerated in gradual SEP events.
In these energy spectra, we have looked for spectral and compositional signatures typically characteristic of impulsive or gradual SEP events.
