　　（1）大气对太阳辐射的削弱作用：①吸收作用：具有选择性，臭氧吸收紫外线，水汽和二氧化碳吸收红外线。对可见光吸收的很少。②反射作用：云层和颗粒较大的尘埃。云层的反射作用最显著。③散射作用：空气分子或微小尘埃，使一部分太阳辐射不能到达地面。

　　（2）大气对地面的保温作用：大气吸收地面辐射并产生大气逆辐射（射向地面的大气辐射），把部分热量归还给地面，云层越厚大气逆辐射越强。

　　5、全球近地面有7个气压带（高低压相间分布），6个风带。

　　（1）低纬度环流：

　　①赤道低压带：因为热力作用形成，气流辐合上升，易成云致雨，形成多雨带。常年受其控制形成热带雨林气候（亚马孙平原、刚果盆地、东南亚的马来群岛）

　　②副热带高压带：因为动力作用而形成，气流在30度纬度上空聚积而下沉，形成少雨带（东亚季风区除外），常年受其控制的地区形成热带沙漠气候（北非的撒哈拉水沙漠、西亚的沙漠、北美美国西部的沙漠、南美智利、秘鲁西部的沙漠、澳大利亚大沙漠）

　　③信风带：由副高吹向赤道低压的气流，在北半球右偏成东北信风，在南半球左偏成东南信风。

　　（2）中纬度环流：

　　④副极地低压带：由来自低纬的暖气流与来自高纬的冷气流相遇运动上升而形成。形成温带多雨带。

　　⑤中纬西风带：由副高吹向副极地低压带的气流，在北半球右偏成西南风，在南半球左偏成西北风，习惯上叫西风，受其常年控制的地区，在大陆西岸形成温带海洋性气候。（欧洲西部、北美西部如加拿大的温哥华附近、南美南端的安第斯山西侧、澳大利亚南端及塔斯马尼亚岛、新西兰等）

　　（3）高纬环流：

　　⑥极地高压带：因为热力作用而形成，冷空气下沉，形成少雨带。不过极地因为气温低，蒸发更少，所以极地属于降水量大于蒸发量的地区，为湿润地区。

　　⑦极地东风带：由极地高压带吹向副极地低压带的气流，在地转偏向力作用下，北半球右偏成东北风，南半球左偏成东南风。

　　（4）气压带和风带的移动：△移动的原因：随太阳直射点的移动而动。△移动方向：就北半球而言，大致是夏季北移，冬季南移。

　　（5）单一气压带或风带作用形成的气候类型：热带雨林气候（赤道低气压带）、热带沙漠气候（副热带高气压带）、温带海洋性气候（中纬西风带）。

　　（6）气压带、风带移动形成的气候类型：热带草原气候（夏季受赤道低气压带控制，冬季受低纬信风带控制）、地中海气候（夏季受副热带高气压带控制，冬季受中纬西风带控制）。
