Examples
“still keeping time to the music like⟳ Harlequin in a pantomime, he thrust a letter into our hero′s hand, and continued his saltation without pause or intermission.”
“the saltation of the great artery”
“Indeed we have⟳ always thought that Mr. Darwin has unnecessarily hampered himself by adhering so strictly to his favourite “Natura non facit saltum.” We greatly suspect⟳ that nature does make⟳ considerable jumps in the way of variation now and then, and that these saltations give⟳ rise⟳ to some of the gaps which appear⟳ to exist⟳ in the series of known forms.”
“Thus, a tap that precedes the final one by a tenth of a second will likely appear⟳ to be midway between the contactors, whereas a tap preceding the final one by only 20 ms will appear⟳ to be virtually superimposed on it. Because the overall experience⟳ is of a stimulus jumping from place⟳ to place⟳, Geldard called the phenomenon saltation.[…]First, saltation can occur⟳ only over a limited distance: A tap on the shoulder will not be drawn toward a later one delivered to the foot.”
“Of extreme importance in the saltation phenomenon is the vertical distribution of particles, as well as total flux, as functions of the wind speed⟳. The formations of all scales of bed formations, from centimeter-size ripples to kilometer-size dunes, are all due to the saltation process⟳.”
“2004, Basil Gomez, Mobile Bed, entry in Andrew Goudie (editor), Encyclopedia of Geomorphology, Volume 2, page 685, Saltation rapidly becomes the dominant type⟳ of motion as the flow⟳ intensity increases further, and at still higher flow⟳ intensities suspension begins to dominate. […] There is also an important difference between the movement of particles by saltation, in air and in water.”
“Rolling is thought to account for about 10% of the mass when creep⟳ and saltation occur⟳ together.[…]The transition from saltation to suspension occurs when the wind speed⟳ exceeds about 15 m/s.”
