 。1)大氣對太陽輻射的削弱作用:①吸收作用:具有選擇性,臭氧吸收紫外線,水汽和二氧化碳吸收紅外線。對可見光吸收的很少。②反射作用:云層和顆粒較大的塵埃。云層的反射作用最顯著。③散射作用:空氣分子或微小塵埃,使一部分太陽輻射不能到達地面。


 。2)大氣對地面的保溫作用:大氣吸收地面輻射并產(chǎn)生大氣逆輻射(射向地面的大氣輻射),把部分熱量歸還給地面,云層越厚大氣逆輻射越強。


  5、全球近地面有7個氣壓帶(高低壓相間分布),6個風(fēng)帶。


  (1)低緯度環(huán)流:


 、俪嗟赖蛪簬В阂驗闊崃ψ饔眯纬桑瑲饬鬏椇仙仙,易成云致雨,形成多雨帶。常年受其控制形成熱帶雨林氣候(亞馬孫平原、剛果盆地、東南亞的馬來群島)


  ②副熱帶高壓帶:因為動力作用而形成,氣流在30度緯度上空聚積而下沉,形成少雨帶(東亞季風(fēng)區(qū)除外),常年受其控制的地區(qū)形成熱帶沙漠氣候(北非的撒哈拉水沙漠、西亞的沙漠、北美美國西部的沙漠、南美智利、秘魯西部的沙漠、澳大利亞大沙漠)


 、坌棚L(fēng)帶:由副高吹向赤道低壓的氣流,在北半球右偏成東北信風(fēng),在南半球左偏成東南信風(fēng)。


 。2)中緯度環(huán)流:


 、芨睒O地低壓帶:由來自低緯的暖氣流與來自高緯的冷氣流相遇運動上升而形成。形成溫帶多雨帶。


 、葜芯曃黠L(fēng)帶:由副高吹向副極地低壓帶的氣流,在北半球右偏成西南風(fēng),在南半球左偏成西北風(fēng),習(xí)慣上叫西風(fēng),受其常年控制的地區(qū),在大陸西岸形成溫帶海洋性氣候。(歐洲西部、北美西部如加拿大的溫哥華附近、南美南端的安第斯山西側(cè)、澳大利亞南端及塔斯馬尼亞島、新西蘭等)


 。3)高緯環(huán)流:


 、迾O地高壓帶:因為熱力作用而形成,冷空氣下沉,形成少雨帶。不過極地因為氣溫低,蒸發(fā)更少,所以極地屬于降水量大于蒸發(fā)量的地區(qū),為濕潤地區(qū)。


  ⑦極地東風(fēng)帶:由極地高壓帶吹向副極地低壓帶的氣流,在地轉(zhuǎn)偏向力作用下,北半球右偏成東北風(fēng),南半球左偏成東南風(fēng)。


 。4)氣壓帶和風(fēng)帶的移動:△移動的原因:隨太陽直射點的移動而動!饕苿臃较颍壕捅卑肭蚨,大致是夏季北移,冬季南移。


 。5)單一氣壓帶或風(fēng)帶作用形成的氣候類型:熱帶雨林氣候(赤道低氣壓帶)、熱帶沙漠氣候(副熱帶高氣壓帶)、溫帶海洋性氣候(中緯西風(fēng)帶)。


  (6)氣壓帶、風(fēng)帶移動形成的氣候類型:熱帶草原氣候(夏季受赤道低氣壓帶控制,冬季受低緯信風(fēng)帶控制)、地中海氣候(夏季受副熱帶高氣壓帶控制,冬季受中緯西風(fēng)帶控制)。
