The shutting down of the vital ocean currents, called the Atlantic ...The Polar Jet Stream is formed as a result of the temperature gradient between the cold polar air mass and the warmer sub-tropical air mass. Since the temperature difference is greatest in the winter, the speed of the Polar Jet Stream is at its highest also in the winter. Its altitude is generally at the 250-300 hPa level.5 Day Forecast of Jet Stream Winds at 300 mb (~30,000 ft.)

As jet streams meander across the United States like a wave, they create patterns by forcing air up or down …Both phases of the NAO are associated with basin-wide changes in the intensity and location of the North Atlantic jet stream and storm track, and in large-scale modulations of the normal patterns of zonal and meridional heat and moisture transport (Hurrell 1995), which in turn results in changes in temperature and precipitation patterns …Mid-latitude Cyclones. Mid-latitude cyclones, also known as extratropical cyclones, are huge weather systems that occur most often during the winter season in the United States.
