Gap winds can range in width from hundreds of feet to over one hundred miles, and in unusual circumstances can be associated with strong winds exceeding 50 knots. These winds are normally quite shallow, extending hundreds of feet to a few thousand feet above the surface, with large changes of wind, or wind shear, at their upper and lateral boundaries. Gap winds are generally strongest when there is a large pressure drop across a gap, although there is one class of gap wind that does not depend on a pressure gradient across the gap. 3, record 2, English, - gap%20wind
Record number: 2, Textual support number: 1 OBS
Although physicially plausible, the venturi mechanism appears to be at odds with most real gap wind situations, where the strongest winds are generally over the exit region of the gap, not at the narrowest section or constriction. There are a number of reasons for the failure of the funnel model. First, there is no rigid lid in the real world. ... Another reason the flow tend to be strongest in the gap exit region is that there is often a synoptic or mesoscale pressure gradient across the gap. 4, record 2, English, - gap%20wind

[The term "gap wind"] was introduced by R. S. Scorer (1952) for the surface winds blowing through the Strait of Gibraltar. ...

Selon les météorologues consultés d'Environnement Canada, l'effet venturi ne peut expliquer à lui seul la force du vent. En effet, une composante liée à l'étalement de l'air, à la sortie du couloir, dans le relief contribue également au phénomène. Par contre, selon le météorologue consulté de Météo-France, il considère que l'effet Venturi englobe l'ensemble des effets qu'un obstacle en forme d'entonnoir fait subir à la vitesse d'écoulement d'un fluide qui le traverse et plus particulièrement l'effet d'accélération de la vitesse du flux dans la zone d'étalement de l'air, phénomène qu'il attribuerait à l'accélération causée par la dépression relative locale, attribuée à l'obstacle placé en amont (surpression en amont de l'obstacle/dépression en aval). 1, record 2, French, - vent%20de%20couloir

A gradient method is recommended for samples that cannot be easily separated by isocratic methods because of their wide k range. In gradient elution the eluent strength is increased during the separation by changing the composition of the mobile phase.

Ocean-floor metamorphism is a type of metamorphism of regional or local extent related to the steep geothermal gradient occurring near spreading centres in oceanic environments. The recrystallisation, which is mostly incomplete, encompasses a wide range of temperatures. The metamorphism is associated with circulating hot aqueous fluids(with related metasomatism) and typically shows an increasing temperature of metamorphism with depth. 5, record 6, English, - ocean%2Dfloor%20metamorphism
