Near the earth s surface , however , friction tends to cause the air to move slightly outward across the isobars 接近地球表面，摩擦力使空气稍微向外越过等压线。

The more abundant the ozone in the atmosphere , the less the amount of uv radiation reaching the earth s surface 臭氧吸收紫外线，大气中的臭氧越多，较少紫外线能到达地面

It distribute on riverbed and both sides , among the terrace , malachite uncover the earth s surface or bury to underground 它分布于河床及两侧阶地中，玉石裸露地表或埋于地下。
Uvb is partially absorbed by the earth s ozone layer and in the atmosphere , with the remainder reaching the earth s surface 短波紫外光部分会被臭氧层及在大气中吸收，馀下的才会落到地面。
As it follows the earth s rotation closely , it is stationary relative to the earth s surface ( hence the name geostationary ) Mtsat - 1r是颗地球同步气象卫星，位于东经140度的赤道上空，距离地面约35 , 800公里。
A positive radiative forcing tends on average to warm the earth s surface ; a negative radiative forcing tends on average to cool the earth s surface 正值的辐射力会使地球表面变暖，负值的辐射力使地球表面变凉。

The uv index is a measure of the solar uv ultraviolet intensity at the earth s surface relevant to the effect on human skin 紫外线指数是量度在地球表面太阳紫外线影响人类皮肤的程度。紫外线对人类皮肤的损害是根据
