Sentence examples for day periodicity from inspiring English sources

No wave feature is evident in the mesosphere during the warming period, although a 12 14 day periodicity is observed after 2 weeks of the warming event, indicating close resemblance to the results of other simultaneous investigations carried out from high latitude Antarctic stations.

At this cycle maximum, a 30 40 day periodicity is found to be dominant among the variations in ¯¯¯B, and this periodicity is found in ¯¯¯A during almost throughout the period 1986–1994.

These processes also exhibit a significant 2 4 day periodicity (Supplementary Fig. 3d) that may reflect progressive cycles of damage accumulation due to tidal grounding, culminating in iceberg disintegration after 2 to 4 days of repeated tensile loading, or amplified wave-notching as a result of increased ocean turbulence during the passage of transient storms15.

These results indicate that the Be-7 concentrations in the air at ground level have 26 day periodicity as a component of time variations and the time variation is caused by the solar modulation of galactic cosmic rays, which corresponds to the variation of the sunspot number due to the rotation of the sun.
