From theCambridge English Corpus This should be a good test of the existence ofsaltation. From theCambridge English Corpus Subsequently,saltationbegins when particles move vertically into the air by a distance of the order of their diameter. From theCambridge English Corpus Contemporary models of evolutionary biology simply do not allow for these kinds of rapid evolutionary saltations, certainly not within the time frame dictated. From theCambridge English Corpus Withoutsaltation, momentum is transported by the turbulence from the wind to the bed surface. From theCambridge English Corpus An alternative explanation is that the fluctuating component of surface pressure may have an influence on thesaltationrate. From theCambridge English Corpus Thence, using the image analysis system on the microcomputer,saltationtrajectory statistics, such as ejection and impact velocities, were calculated. From theCambridge English Corpus The effects of particle density on thesaltationtrajectory could not be studied here independently of the more significant effects of friction velocity and particle size. From theCambridge English Corpus Even so, within thesaltationregime, there are interesting variations in the statistics of the particle motion according to the size, type and distribution of particles. From theCambridge English Corpus In fact the explanation may be that there is a transition fromsaltationto suspension when u /ut > 1.5. From theCambridge English Corpus Bagnold (1941) also identified four distinct subprocesses in the sandsaltationsystem: aerodynamic entrainment, the grain trajectory, the grain/bed collision and wind modification. From theCambridge English Corpus Note that in more dilute flows, such as in a powder cloud or asaltationlayer, other segregation mechanisms dominate and the direction of segregation may reverse. From theCambridge English Corpus Anderson (1989) describedsaltationin terms of an analogy with a biological population. From theCambridge English Corpus Knight instead favors a model that leads to an abruptsaltationfrom ' protolanguage ' to the sudden appearance of full human linguistic ability.

In the "lower flow regime", the natural progression is from a flat bed, to some sediment movement (saltationetc.), to ripples, to slightly larger dunes.
