jet streamNarrow band of very fast wind (velocities of over 150 kph/95 mph) found at altitudes of 10-16 km/6-10 mi in the upper troposphere or lower stratosphere. Jet streams usually occur about the latitudes of the Westerlies (35°−60°). The jet stream may be used by high flying aircraft to speed their journeys. Their discovery of the existence of the jet stream allowed the Japanese to send gas-filled balloons carrying bombs to the northwestern USA during World War II. How to thank TFD for its existence?
