2. Meteorology. Each of a number of narrow, variable bands of very strong air currents encircling the earth in the upper troposphere or lower stratosphere, moving typically from west to east.There are usually two or three jet streams in each of the northern and southern hemispheres, typically hundreds of kilometres wide and a few kilometres deep; speeds can exceed 400 km per hour (240 m.p.h.). Jet streams follow a meandering course owing to the phenomenon of Rossby waves (see Rossby n. 2), and have a strong influence on the movement of cyclonic systems.
