【导语】逍遥右脑整理《高二地理知识点:物质运动和能量交换2》,以及最全的高考备考资料,有语文、数学、英语、物理、化学、生物、政治、历史、地理、文综、理综复习学习资料,复习讲义、听力材料、作文素材,历年真题试题下载及答案解析,完备的资料库为广大考生提供全面的备考参考。
(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)。
