Given the implications of the hydrostatic equation,we would expect that
A)pressure be independent of altitude.
B)cold, dense air would have a greater vertical pressure gradient than would warm, light air.
C)differences in temperature on either side of a cold front should not have any significant effect on upper-level pressure.
D)differences in temperature on either side of a warm front should not have any significant effect on upper-level pressure.

Question

Quizplus · Accepted Answer

The hydrostatic equation states that pressure decreases with altitude. Therefore, pressure is not independent of altitude (choice A is incorrect). The vertical pressure gradient is determined by the density of the air, which is influenced by its temperature. Cold, dense air will have a greater vertical pressure gradient than warm, light air (choice B is correct). Differences in temperature on either side of a front will have significant effects on upper-level pressure, which is why choices C and D are incorrect.
