The inner heliosphere that Ulysses explores is characterized by many short term events, superimposed on the long-term baseline, which have apart from their strong temporal and radial dependence easily recognizable latitudinal and azimuthal features.
His analysis revealed a relentless, long-term increase superimposed on the seasonal cycle, a trend that was dubbed the Keeling Curve.
Ice sheet initiation is studied using the topography before uplift and after each phase of uplift by applying different forcing conditions relevant for the late Cenozoic, which was characterised by long-term cooling superimposed by cold and warm excursions.
It appears that the exercise-training programme was sufficient to accelerate the natural recovery process in the short term and superimpose a beneficial physiological adaptation in the intervention group vs controls.
"The EU-attributable particulates in London are likely to have significantly contributed to the violations, because they raised the background concentration on which local short-term peaks were superimposed," explains Steven Barrett.
A weak long-term trend might be observed in the 0.5- to 0.9-Hz band (Figs. 4a, 5a), although this long-term trend is superimposed into the coseismic and postseismic velocity changes associated with the Greenville earthquake.
Consequently, there are short-term fluctuations that are superimposed upon a long-term trend for decreasing ice.
Inferred magnitudes of short-term (105 yr) fluctuations superimposed on the longer-term rises and falls range from 20 to > 70 m during the early to mid-Pennsylvanian and are substantially reduced (≤ 20 m) during the late Pennsylvanian.
Somewhere between the meme as christened by Richard Dawkins (that is, a component of culture that is disseminated through human interaction) and the term as it now exists in the popular imagination (a graphic with text superimposed to side-splitting effect), lies the internet meme as this column understands it: a phrase or image or idea that spreads rapidly through the virtual consciousness.
It could even be possible that short-term climatic fluctuations superimpose a long-term trend of aridification and contribute to ongoing change of environmental selective pressures.
