Is the air pressure high on sunny days or cloudy days? Why? What is the general difference?

The air pressure on sunny days is higher than that on cloudy days.

Generally speaking, the air humidity on cloudy days is higher than that on sunny days, so there is more water vapor in the air. Because the density of water vapor is lower than that of air, the air pressure on sunny days is higher than that on cloudy days.

There is no actual comparison about the difference, which needs professional answers. sorry
