claim: “The jet stream forms a boundary between the cold north and the warmer south, but the lower temperature difference means the winds are now weaker.
evidences.evidence_id: Global warming:37
evidences.article: Global warming
evidences.evidence: As the temperature difference between the Arctic and the equator decreases, ocean currents that are driven by that temperature difference, like the Gulf Stream, are weakening.

evidences.evidence: This in turn reduces the temperature gradient that drives jet stream winds, which may eventually cause the jet stream to become weaker and more variable in its course.

evidences.evidence: If two air masses, one cold and dense to the North and the other hot and less dense to the South, are separated by a vertical boundary and that boundary should be removed, the difference in densities will result in the cold air mass slipping under the hotter and less dense air mass.

evidences.evidence: Therefore, the strong eastward moving jet streams are in part a simple consequence of the fact that the Equator is warmer than the North and South poles.
