A)the surface level and upper level of the troposphere are two distinct layers.
B)the Bjerknes model of cyclogenesis gives the best explanation for the formation and life of mid-latitude cyclones.
C)upper-level divergence has little impact on the surface.
D)the temperature at the surface can affect air flow at upper levels of the atmosphere.

Question

Quizplus · Accepted Answer

The temperature at the surface can affect the air flow at upper levels of the atmosphere through the concept of thermal advection. As warm air rises from the surface, it causes a low-pressure system at the surface, which in turn causes cold air to sink from the upper levels, forming a high-pressure system. This impacts the upper-level flow, as the movement of the high and low-pressure systems can affect the movement of the upper-level jet stream.
