例如，如果没有树木来吸收太阳的辐射并提供树荫，那么太阳辐射就会完整地到达地面。

For instance, without a tree to absorb radiation from the Sun, to offer shade, the full intensity of that radiation reaches the ground.

上图中，相对较低的积云（低于4500米）很可能是地面附近的水汽受太阳辐射，与低层大气发生对流所形成的。

The relatively low-level cumulus clouds (below 15,000 feet) shown in this image are likely the product of moisture near ground level being cooked by the Sun and convected into the lower atmosphere.
