下图为我国某地区气象要素分布状况,甲、乙两地水平直线距离约为220千米。读图完成下列问题。

小题1:甲、乙两地气候的最大差别表现为

A.气候类型

B.气温年较差

C.年降水量

D.盛行风向小题2:造成甲、乙两地气候差异的最主要因素是

A.地理纬度

B.海拔高度

C.大气环流

D.山地坡向小题3:图中所示山地为

A.天山山脉

B.昆仑山脉

C.横断山脉

D.大兴安岭

答案

小题1:C

小题2:D

小题3:A

题目分析:

小题1:此图所用的坐标较多,总共有三个:气温、年降水量、海拔高度。经过甲点作一垂线,该垂线分别与七月均温线、一月均温线、年降水量线、地形剖面线存在一交点(如下图①~④)。

下面我们以①点为例来说明这类坐标的读法。如图所示,因为点①是该垂线与七月均温线的交点,故而该点的纵坐标应该表示甲地七月均温。我们经过①点向左作垂线,与表示气温的坐标轴交点即甲地七月均温,读出该值约为23℃。对于点②、③、④,分别为甲地的一月均温、海拔高度、年降水量,它们的数值分别为-11℃、900米、80毫米。同样道理可以读出乙地的信息:26℃-七月均温,-14℃-一月均温,290毫米-年降水量,700米-海拔高度。经过比较,两者最大的差异体现在年降水量。

小题2:影响降水量的主要因素有:大气环流、海陆位置、地形、洋流、人类活动。根据题目中信息,甲、乙两地分居与某山脉的南北两侧,从而判断出主要影响因素是地形。从降水量来看,该处山脉北坡是迎风坡,乙地空气受地形影响被迫上升形成较多的降水。

小题3:从图中判断,该山脉的走向为东西走向。东西走向的山脉:我国东西走向的山脉主要有三列:自北向南依次为:①天山——阴山;②昆仑山 ——秦岭;③南岭(读我国地形图,明确它们的位置)。其中秦岭是划分我国南方与北方的重要地理界线。根据上题分析结论,试题中山脉北部为迎风坡,可知应该是天山山脉。天山北坡受大西洋和北冰洋水汽影响,年降水量大于南坡。
