If upper-level divergence exceeds surface convergence, the air pressure at the center of the low will ____, and the isobars will become ____ tightly packed.

Question

Quizplus · Accepted Answer

When upper-level divergence exceeds surface convergence, it means that more air is being removed from the top of the atmospheric column than is being added at the bottom. This leads to a decrease in mass and therefore a decrease in air pressure at the center of the low. As the pressure decreases, the pressure gradient increases, causing the isobars to become more tightly packed.
