The ground surface radiates longwave energy to the sky, and net radiation becomes negative. The surface cools. This means that air near the surface also cools, as we saw in Figure 3.6. If the surface stays cold, a layer of cooler air above the ground will build up under a layer of warmer air, as shown in Figure 3.11. Figure X also indicates the typical changes in air temperature that take place over the course of a day. The largest change in air temperature happens just above the ground surface with much less change higher up. The reason is that the ground surface temperature responds more rapidly to changes in radiation than the air.Physics 8th Edition By John D. Cutnell & Kenneth W.
