Todays Jet Stream

The strongest jet
stream winds in the
atmosphere, on the
average, are most
likely found over
Japan, at a height of
20,000 to 40,000 feet.
Here, wind speeds can
reach 250 mph.
American B-29 bomber
pilots flying over Japan during World War II
discovered the location
of the planet's strongest
winds. Westward flying
bombers found themselves
appearing to hover almost
motionless over a target--
and its defenders.
