Question

multiple choice 1 point
which of the following is a potential effect of a strong jet stream?
a strong jet stream could cause a decrease in wind speed across the globe.
a strong jet stream could cause more frequent and intense storms due to enhanced temperature contrasts.
a strong jet stream causes an increased stability in weather patterns.
a strong jet stream causes no impact on local weather conditions.

Explanation:

Jet streams are fast - flowing, narrow air currents in the atmosphere. A strong jet stream can lead to more frequent and intense storms. This is because jet streams can influence weather systems. For example, they can help to lift air masses, which is a key factor in storm formation. An increased temperature contrast (which is related to jet stream strength) can enhance the forces that drive storm - related processes.
On the other hand, a strong jet stream does not cause no impact on local weather (it has a significant impact). It does not cause increased stability (as it is associated with dynamic weather changes). And it does not cause a decrease in wind speed across the globe (jet streams are high - speed wind currents).

Answer:

A strong jet stream could cause more frequent and intense storms due to enhanced temperature contrasts.
