Test your knowledge with these top questions!
What scientific effect, caused by Earth's rotation, gives the jet stream its powerful west-to-east flow?
The Coriolis effect deflects northward-moving air to the right in the Northern Hemisphere due to Earth's rotation, creating the jet stream's dominant west-to-east winds at altitudes of 9-16 km.
Used by pilots to save fuel and time, these high-altitude rivers of air primarily flow in which direction?
Jet streams, narrow bands of strong winds at high altitudes, flow primarily west to east due to Earth's rotation and the Coriolis effect, enabling pilots to save up to 10% on fuel for eastbound flights.
The large, meandering curves in the jet stream that cause prolonged weather events are known by what wave-like name?
Rossby waves, named after meteorologist Carl-Gustaf Rossby, are planetary-scale undulations in the atmosphere driven by Earth's rotation, causing the jet stream to meander and prolong weather extremes like droughts or floods.
Jet streams, fast-flowing air currents, are found in which atmospheric boundary layer located just below the stratosphere?
Jet streams occur at the tropopause, the boundary between the troposphere and stratosphere, where sharp temperature gradients create powerful wind shear.
What WWII weapon, a type of balloon bomb, was designed by Japan to ride the powerful jet stream across the Pacific Ocean?
The Fu-Go balloon bombs, launched by Japan in 1944-1945, carried incendiary devices intended to start forest fires in the US, but only about 300 of the 9,300 released reached North America.
