claim: This means the jet stream meanders more, with big loops bringing warm air to the frozen north and cold air into warmer southern climes.”

evidences.evidence: According to the UK Met Office, the jet stream deviated[clarification needed] to the south (bringing cold air with it) as a result of unusual contrast between cold air in Canada and mild winter temperatures in the United States.

evidences.evidence: The path of the jet typically has a meandering shape, and these meanders themselves propagate eastward, at lower speeds than that of the actual wind within the flow.

evidences.evidence: The wind does not flow directly from the hot to the cold area, but is deflected by the Coriolis effect and flows along the boundary of the two air masses.
