Polar vs. Subtropical Jet Streams

Two primary jet streams influence agricultural regions: thee polar jet t e subtropical jet. The polar jet sits near thee boundary of Arctic air, typically affecting thee United States, Canada, Europe, and northern Asia. Its valigations are responsible for thee movement of cold fronts andd winter storms. Thee subtropical jet is found further sout, influencing weatheir materns in thee southern United States, thee Mediraneen, the Middle Eass, and parts asia.

The El Niño -Southern Oscillation (ENSO), the Arctic Oscillation (AO), ande North Atlantic Oscillation (NAO) all fecret the jet straem 's position and intensity.
