Will a patch of ground in direct sunlight have a higher or lower pressure than a patch of ground in shade?

A patch of ground in direct sunlight will generally have a higher pressure compared to a patch of ground in the shade. This is due to the heating effect of sunlight, which warms the air above the ground, causing it to expand and rise, thereby creating a lower pressure area. In contrast, shaded areas remain cooler, leading to denser air and relatively higher pressure. However, the differences in pressure may be minimal and influenced by other environmental factors.
