Question

Quizplus · Accepted Answer

When a jet stream has a meridional (north-south) flow pattern, it can transport warm air from the tropics to the middle latitudes and cold air from the polar regions to the mid-latitudes. This creates larger temperature gradients and leads to more heat transfer across the globe than when the jet stream has a zonal (east-west) flow pattern.
