But passengers won't just have to keep their seat belts locked, they may have to stay locked in for longer,
as jet stream wind patterns change.
However, when these temperature gradients decrease in just the right way, a weakened «double peak» jet stream arises with the
strongest jet stream winds located to the north and south of the mid-latitudes.
Pushed
by jet stream winds, the line of clouds began to extend westward from Asia on October 12.
The atmosphere in many northern regions like Canada (Northern America) or Europe is currently dominated by
westerly jet stream winds.
Because the temperature contrast between the frigid Arctic and the milder mid-latitudes is what drives the
powerful jet stream winds that guide weather systems, what happens in the Arctic is bound to have some sort of influence on the world's weather.
Synoptic scale weather disturbances tend to form in the regions of
maximum jet stream wind speed and propagate downstream.
He added, «While La Niña can produce similar patterns, there is no indication that
these jet stream winds are related to the developing weak La Niña.»
They are stronger than
jet stream winds, which are less than 70 mph in the troposphere below.
