The jet stream is a fragmented global wind flow that encircles the mid-latitudes in a wavelike pattern. Embedded within this global wind belt are jet streaks. A jet streak is a segment of the jet stream that has relatively high velocity winds. ... Jet streaks are caused by a large low-level temperature gradient, thus they are more intense in the cool season when the differential in temperature between the polar regions and tropical regions is largest. Jet streaks are analyzed near the 300-mb level. 4, record 1, English, - jet%20streak

Some authors consider "jet stream core" and "core of the jet stream" synonyms with "jet streak." In fact, a "jet stream core" is "a line, within the jet stream, along which the wind speeds are maximum both in the vertical and horizontal." The "jet streak" is a "segment within the jet stream core where the wind reaches its greatest speed." There could be more than one "jet streak" within a "jet stream core." The French equivalent of "jet stream core" is "coeur du courant-jet." 7, record 1, English, - jet%20streak

Le cœur du courant-jet constitue la partie centrale du courant-jet et fait en principe tout le tour de la planète aux latitudes tempérées, tandis que les «jet streaks» ou «rapides du courant-jet» correspondent aux portions du courant-jet où les vents sont les plus forts. Le terme français incite d'ailleurs à faire une analogie en imaginant le courant-jet comme une rivière ponctuée de rapides!
