Given the implications of the hydrostatic equation, we would expect that Group of answer choices
A) Differences in temperature on either side of a cold front should not have any significant effect on upper-level pressure.
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 warm front should not have any significant effect on upper-level pressure.
D) Pressure be independent of altitude.
