English term or phrase: jet stream
Definition from National Weather Service Upton, NY:
Relatively strong winds that are concentrated in a narrow band in the atmosphere. Jet Streams are usually thousands of kilometers long, hundreds of kilometers wide but only a few kilometers thick. They are usually found between 6 and 10 miles above the surface.

Example sentence(s):
  • This page displays the current location of the Atlantic jet stream and also the forecast position and intensity over the next seven days. metcheck
  • One of the main drivers of world’s weather is moving due to climate change. As this ScienCentral News report explains, scientists are finding that the jet stream, that river of air that pushes storms across the country, is moving towards the north and south poles. ScienCentral Archive
  • The jet stream is useful for the prediction of temperature. The jet stream divides colder air to the north from warmer air to the south. The transition between temperatures on each side of the jet is very abrupt.

Definition from Wikipedia:
Suihkuvirtaus on ylhäällä troposfäärissä kulkeva putkimainen nopean tuulen vyöhyke. Suihkuvirtauksen leveys on 300–500 kilometriä ja paksuus korkeintaan noin 3 kilometriä. Keskimääräinen nopeus on 30–60 m/s. Suihkuvirtaus sijaitsee suunnilleen matalapaineen reitillä ja ilmamassojen rajalla. Se kiemurtelee käärmemäisesti, ja näkyy monesti satelliittikuvissa selvänä nauhamaisena pilvimuodostumana.

Example sentence(s):
  • Suihkuvirtaustermiä käytetään yleensä ylätroposfäärissä eli noin 5-10 kilometrin korkeudella olevasta ympäristöään selvästi voimakkaamman tuulen alueesta. Käytännössä suihkuvirtausalueet ovat pitkiä ja melko kapeita, jotka mutkittelevat etelä-pohjoissuunnassa matala- ja korkeapaineiden sijainnin mukaan. Pohjoisella pallonpuoliskolla suihkuvirtausten akseli on leveyspiirillä 30°N noin 12 km korkeudella, missä tuulen nopeus on tyypillisesti 40 m/s (= 144 km/h). - Ilmatieteen laitos
