Sentence examples for gradual event from inspiring English sources

Thus, when the usual classification refers to a gradual event, this fails to distinguish between particle populations of three distinct acceleration histories.

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.

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).

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.

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.

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.

Data from this study suggest that the loss of ancestral genes resulted in the loss of functional genes of M. leprae's ancestor and its divergence from M. tuberculosis and that pseudogenization events appear to be recent gradual evolutionary events in M. leprae's lineage (within the last 20 million years).

The propagation ranges of protons and other ions in the impulsive SF events are narrow compared with those in the gradual CME events (e.g., Reames 1999); thus, more 3He-enriched SF particles were partly prevented from arriving at the Moon.

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.
