2010年气象知识竞赛题目及答案50题

2010年气象知识竞赛题目及答案(50题) 1.2010年世界气象日的主题是世界气象日--致力于人类安全和福祉的60年。 2.中华民族的文化与自然环境息息相关,从冷、暖、干、湿,到春、夏、秋、冬;从风、云、雷、电,到雨、雪、霜、雾……它们在成语世界里也可谓是“气象万千”。你能说出四个与气象有关的成语吗?风干物燥、风雨交加、温暖如春、电闪雷鸣、春意盎然。 3.大气的主要成分是什么?氮、氧、氩、二氧化碳和水汽 4.什么叫逆温层?它对空气污染有什么作用?一般情况下,在低层大气中,通常气温是随高度的增加而降低的。但有时在某些层次可能出现相反的情况,气温随高度的增加而升高,这种现象称为逆温。出现逆温现象的大气层称为逆温层。在逆温层中,较暖而轻的空气位于较冷而重的空气上面,形成一种极其稳定的空气层,就象一个锅盖一样,笼罩在近地层的上空,严重地阻碍着空气的对流运动,由于这种原因,近地层空气中的水汽、烟尘、汽车尾气以及各种有害气体,无法向外向上扩散,只有飘浮在逆温层下面的空气层中,形成并加重大气污染。 5.你知道什么是灰霾天气吗?把大气中悬浮的大量微小尘粒、烟粒或盐粒的集合体,使空气混浊,水平能见度降低到10km以下的一种天气现象称为阴霾天气。 6.1860年以来的一百多年间,全球地表温度的年平均值升高了 0.6℃,其中,最暖的十年都出现在1990年以后。这是科学家称为“全球气候变暖”的主要依据。 7.1982年,科学家首次发现臭氧减少的现象是在(南极)上空。 8.你知道风、雨、雷电等天气现象发生在空中哪一层吗?对流层 9.你知道4级风地面物体的征象是什么吗? 能吹起地面灰尘和纸张,树枝动摇,高草呈波浪起伏。 10.请你说出“九九歌”的内容。一九二九不出手;三九四九冰上走;五九六九沿河看柳;七九河开八九雁来;九九加一九,耕牛遍地走。 11.什么是气候资源?气候资源具有哪些特征?气候资源是自然资源的一部分,是有利于人类经济活动的气候条件。包括太阳辐射、热量、水分、空气,风能等。它是一种取之不尽,又是不可替代的。气候资源具有以下几个特征:第一,不可或缺性。第二,自然性。第三,利弊相生性。第四,多样性。 12.请说出“气象”“天气”和“气候”的区别是什么?“气象”,是一个统称,它是指发生在天空中的风、云、雨、雪、霜、露、虹、晕、闪电、打雷等一切大气的物理现象;“天气”,指一个地方瞬时或较短时间内的风、云、降水、温度、气压等气象要素的综合状态;“气候”,则是指整个地球或某一个地区、某一城市年、季、月或一段时期内有规律性的天气特征加以概括总结,得到的大气平均状况。 13.我国劳动人民在长期的生产和生活中,总结出很多看云识天气的谚语。请对出“天上钩钩云,地下雨淋淋”。 14.看风也能识天气。请对出“夜夜刮大风,雨雪不相逢。” 15.什么是“倒春寒”?在气象上,把入春后“前暖后冷”的天气称为“倒春寒”。入春是指气温上升到候(5天)平均气温高于10℃以后。在这个条件下,如遇到本应逐渐回暖的气候,在受到较强冷空气影响后,气温会突然下降,降至常年同期平均气温值以下,就是所谓的“倒春寒”了。 16.对于多数人来说,最舒适的环境温度是多少?22-24度 17.你知道什么是空间天气吗?由于太阳上出现的耀斑和日面物质抛射等剧烈活动,给地球磁层、电离层和中高层大气、卫星运行和安全、以及人类健康,带来严重影响和危害,

气象常识

气象常识 一、气象名词 (一)天气图与气象卫星云图 用于分析大气物理状况和特性的图统称为天气图。主要有地面天气图和高空天气图两种。卫星云图是气象卫星拍摄发送回来的云的图片,能显示出大范围的云况,是天气预报的参考依据之一。 (二)地面等压线和3000m上空,308线 由于降水云系主要形成于3000m左右的上空,因而分析700hPa 等压面的天气形势尤为重要。气象广播中经常提到“3000m上空,308线在......一线”,指的是700hPa等压面的天气形势,为了便于理解,故称为“3000上空”,308线就是气压为700Pa,位势高度为3080m (以什米为单位,即位势为308什米)的各地连成的等高线。 (三)高压、高压脊 在分析天气图时,有些等压线是闭合曲线,如果其中心的气压值比周围高,这个区域叫做高压控制的区域,其中气压最高的地方,称为“高压中心”。自高压中心向外,气压逐渐下降。由于沿各个方向气压的下降率不同,所以等压线不是以高压中心为圆心的一组同心圆。气压降得慢的部位,等压线就从高压中心向外凸出,该凸出部分,叫做“高压脊”。在高压(或高压脊)控制的地方,空气由于受地球自转的作用,不断沿顺时针方向向外流散,在它的上空,就会有空气下沉补充流走的空气。在高压中心附近,一般都是晴到少云天气。 (四)低压、低压槽 在分析天气图时,如果闭合等压线内的气压比周围低,就称为低气压(简称“低压”)。低压区域内气压最低的地方,叫做“低压中心”。自低压中心向外,气压逐渐升高,但是沿各个方向气压的升高率不同,

气压升高缓慢的部位,等压线就自低压中心向外凸出,该处的气压低于毗邻三面的气压,形似凹槽,故称“低压槽”。在低压系统影响时易出现阴雨天气。 (五)倒槽.气旋波 低压槽一般自低压中心伸向偏南或西南方,槽向北或东北方向开口。若低压中心伸向北或东北方向槽向南或西南开口,地面天气图上等压线呈“∧”型的低槽叫做“倒槽”。如果在低压的西北侧有冷空气侵入,东南侧有暖空气绕低压中心旋转运动,这样的低压中心就叫“气旋波”(或叫“气旋”)。 (六)槽线、切变线 槽线,就是连结自低压中心到低压槽内气压最低的点而成的一条线,通常呈东北~西南向或北~南向,槽线的两侧风向有明显转折。在水平方向,槽前盛行西南暖湿气流,槽后为干燥的西北气流。在垂直方向,槽前有上升运动,如水汽充沛,常产生降水;槽后为下沉气流,天气转晴。 在槽线的两侧有明显的温度差异和风向的转变。如果在某一地区范围内,只有风的转变,没有明显的温度差异,这就叫“切变线”。当切变线形成后,由于两测风向、风速的不一致,使切变线区域内形成辐合带,使大量气流上升,因此在切变线影响下,常出现阴雨 (七)冷锋、暖锋、静止锋 性质不同的冷暖气团相遇而形成的交界面,通称“锋面”。锋面分冷锋、暖锋、静止锋等。因为锋面附近,是冷暖空气的交会地带,因而这里往往伴有云、雨或大风等天气现象。 冷锋,就是冷空气势力校强,冷气团向暖气团地区前进,它们的交界面叫做“冷锋”(意即冷空气前锋)。冷锋一般向南到东南方向移动,

(1)关于该国的叙述,正确的是() ①位于低纬度②地形以山地丘陵为主③河流水位季节变化小④A 地降水比 B 地多⑤1月份气温最低 A. ①②③ B. ①②⑤ C. ②③④ D. ③④⑤ (2)下列最适宜该国发展的农业是() A. 畜牧业 B. 橡胶种植 C. 水稻种植 D. 棉花种植【答案】(1)C (2)A 【解析】【分析】(1)由图可知,该国全部位于中纬度地区,地形以山地丘陵为主,大部分属于温带海洋性气候,全年降水均匀,河流的水位季节变化小,A 地处于迎风坡,降水比B地多,该国属于南半球,1月份时气温最高,故选C。(2)由图可知,该国大部分是位于40-60度之间的大陆西岸,以全年温和湿润的温带海洋性气候为主,这种气候适合多汁牧草的生长,有利于发展畜牧业,不利于发展种植业,故选A。 【点评】(1)新西兰位于太平洋西南部,领土由南岛、北岛及一些小岛组成,以库克海峡分隔,南岛邻近南极洲,北岛与斐济及汤加相望,首都惠灵顿以及最大城市奥克兰均位于北岛。新西兰常年受盛行西风的影响,形成了终年温和湿润的温带海洋性气候,四季温差不大,植物生长十分茂盛,森林覆盖率高。 (2)新西兰天然牧场或农场占国土面积的一半,广袤的森林和牧场使新西兰成为名副其实的绿色王国。当地的温带海洋性气候终年温和多雨,使得作物光照不足,谷物生长条件较差。但适合多汁牧草的生长,于是新西兰发展了举世闻名的乳畜业,主要生产乳制品。 3.某校地理兴趣小组观测本校某月全部四次降水。统计出当月的降水量是() A. 6mm B. 9mm C. 12mm D. 36mm 【答案】 D 【解析】【分析】解:每个月的降水量是这个月每一天降水量的总和;题干中当月降水量=6mm+10mm+8mm+12mm=36mm。 故答案为:D。
