Meaning of triple point | Babel Free

Definitions

1. The unique temperature and pressure at which the solid, liquid and gas phases of a substance are all in equilibrium.
2. A point where the incident shock wave, the reflected shock wave, the Mach stem, and one slipstream meet.
3. A point where a curve or surface intersects itself along three arcs.
4. The intersection of an occluded front, cold front, and warm front.
5. The point where two boundaries, such as a dry line, outflow boundary, or cold front, intersect.
6. A point where three plates intersect.

Examples

“A solid sublimes only when the pressure of its vapor is below that of the triple point for that substance.”

“When the incident shock wave is at position “a” the second triple point, T, is still inside the zone where the vibrational degree of freedom has not yet reached its equilibrium and the dissociational degree of freedom is still frozen at that position, as its excitation can be assumed to start only after vibrational equilibrium is reached.”

“A triple point may have a convex Mach stem, in which case the SS points upward.”

“One constant, however, is that the flow, just downstream of the incident shock, at a triple point, must be supersonic.”

“The number of the distinguished edges whose orientations point towards the triple point is exactly one, or exactly two.”

“A cubic surface with a triple point (a cubic cone) may or may not be rational.”

“A further investigation is made of the reasonably-close relationship between some multiple tornado outbreaks in the British Isles and the passage of frontal-system triple points (TPs) using, principally, TORRO records and the hourly British Isles charts archived by the Meterorological Office at Bracknell.”

“...together at the point of occlusion, or triple point, where conditions are favorable for formation of a new cyclone, sometimes called a secondary cyclone.”

“The point where occluding starts is the triple point, because there are three air masses involved: that ahead of the occlusion, the warm air aloft, and the air behind the occlusion, or where the cold, warm and occluded fronts meet.”

“Few, however, reach the African continent; some dissipate in the intertropical-front bulge east of southern Africa; others form triple points with the temperate fronts available for recurving anywhere between Australia and the Seychelles-Madagascar-Mascarenes (Reunion-Mauritius-Rodriguez) sector.”

“It is concluded that the severe storms formed in close proximity to a "triple point" (TP), at which a synoptic cold front and "insolation-enhanced" warm front intersected.”

“Such a 'piecrust model' has been used to explain the generation of triple points which can give rise to splitting of a continental body.”

“Microstructures like static mineral growth, equilibrated grain boundaries with triple points especially in quartz and feldspar fabric and the lack of plastic crystal lattice deformations even in quartz indicate that metamorphism outlasted deformation.”

“End-member stable triple point configurations are indicated in which the triple point is fixed to the North or South American plates (dashed grey lines) or fixed to the Caribbean Plate (dotted grey lines).”
