1、专题三大气一、单项选择题1.(2009年高考上海综合卷)2008年初的雪灾与大气的逆温现象有关。逆温是指对流层中气温随高度上升而增高的现象。下列四图中表示近地面逆温现象的是()。对流层顶高度高度高度高度对流层顶对流层顶对流层顶气温气温气温气温ABCD【答案】A【解析】审题时注意“近地面逆温”而非整个对流层逆温。找出图中近地面气温随高度上升而增高的即可。【考点定位】逆温现象读某日08时地面天气图(图6)和文字信息,回答10~11题。orientationofenterpriseandbusinessinvestmenttrendsandinvestment,activ

7、“露重见晴天”的说法。就此现象,下列叙述正确的是A.天空云量少,大气保温作用强B.地面辐射强,地表降温慢C.空气中水汽少,地表降温慢D.大气逆辐射弱,地表降温快【答案】D【解析】“露重见晴天”与大家熟悉的“十雾九晴”的理解一样。露是空气中水汽以液滴形式液化在地面覆盖物体上的液化现象。夜间气温下降,越近地面冷却越快,形成与白天相反的下冷上热的温度分布,当地面温度冷却到使贴地面空气中的水汽含量达到饱和时,地面物体上开始观察到露滴生成。“露重见晴天”就是说早上多露,则说明夜间气温下降快,气温低,即可知D项:大气逆辐射弱,地表降温快是正确的。【考点定位】该题考查对日常生
