Answer:
jet stream
Step-by-step explanation:
Jet streams or air jets are wind currents that move the planet from west to east at high altitudes in a wavy pattern. Among the most powerful jets are the polar jets, which occur around 7 and 12 km altitude, between latitudes 30 ° to 60 °. The width of a jet stream is a few hundred kilometers, while its vertical thickness is no more than 5 km. Jet currents can also be defined as a fast moving air range that moves from west to east, high in the atmosphere. This air stream constantly bends and descends to move climate systems.
