Jugavoolu all mõeldakse tavaliselt tugeva tuulega kitsaid alasid troposfääri ülaosas ja stratosfääri alaosas. Jugavoolud on mõne km paksused, kuid pikkus küünib kuni kümnete tuhandete kilomeetriteni ning õhu liikumise kiirus jugavoolu teljes maksimaalselt 700 km/h, tavaliselt aga 100-300 km/h.

SIGWX forecasts shall include the following items: a) tropical cyclone provided that the maximum of the 10-minute mean surface wind speed is expected to reach or exceed 17 m/s (34 kt); Appendix 2 Annex 3 — Meteorological Service for International Air Navigation APP 2-3 14/11/13 b) severe squall lines; c) moderate or severe turbulence (in cloud or clear air); d) moderate or severe icing; e) widespread sandstorm/duststorm; f) cumulonimbus clouds associated with thunderstorms and with a) to e); Note.— Non-convective cloud areas associated with in-cloud moderate or severe turbulence and/or moderate or severe icing are to be included in the SIGWX forecasts. g) flight level of tropopause; h) jet streams; ...
Jet streams are characterized by wind motions that generate strong vertical shearing action, which is thought to be largely responsible for clear air turbulence.
