During the March, 1993 storm off the coast of Texas, a region of ____ air in the upper air above the storm caused the rapid decrease of surface pressure, leading to the development of a wave cyclone.
A)diverging
B)converging
C)blowing straight from west to east
D)increasing in speed uniformly over a broad area
E)blowing from north to south

Question

Quizplus · Accepted Answer

Diverging air in the upper atmosphere leads to a decrease in surface pressure because as air diverges aloft, it reduces the mass of air directly above, causing surface pressures to drop. This can lead to the development of a wave cyclone as the pressure gradient forces air to move from areas of higher to lower pressure, creating cyclonic circulation.
