Upper air winds:

Question

Upper air winds:

Quizplus · Accepted Answer

Upper air winds, also known as jet streams, are generally faster than surface winds. This is because they are influenced by different factors, such as pressure gradients and temperature contrasts, and are located at higher altitudes where there is less friction from the Earth's surface.

Answer: C 
 Upper air winds are affected by the Coriolis force, just like surface winds. In fact, the Coriolis force is what causes the jet streams to exist in the first place. The deflection of winds due to the Earth's rotation is stronger at higher altitudes, which leads to the formation of high-speed currents that flow from west to east.

Therefore, choices A and D are incorrect.
