问题 单项选择题

下列有关气象的表述不够准确的是( )。

A.寒潮俗称寒流,是冬季的一种灾害性天气,是指北方的冷空气大规模地向南侵袭我国,造成大范围的急剧降温和偏北大风的天气过程。我国气象部门规定,冷空气侵入造成的降温,一天内达到10度以上,此次冷空气的爆发过程即可称为寒潮过程
B.从我国江淮流域到日本南部,每年初夏6~7月问,都有一段连续阴雨时期,降水量大,次数多,这时正值江南梅子成熟季节,所以称为“梅雨”。又由于这段时间多雨阴湿,衣物容易受潮发霉,因而又俗称“霉雨”
C.夏日的地表不断受到酷日的照射,气温迅速上升,而且最热的时候是在午后一两点钟。这时候,含有大量水蒸气的热空气因受热而不停地猛烈上升,形成大块的浓积云,当积云上升到七八千米,甚至九千米的高卒时.形成了雷雨云。到了这么高的时空,云的顶部温度在零摄氏度以下,因为温度降低,使空气中蕴藏的大量水蒸气冷却凝结成水滴,水滴又互相碰撞并扩大,便落地成雨了
D.清明时节江南经常是阴雨连绵。这种天气的出现主要原因之一是:冬天,来自西伯利亚的冷空气霸占着江南,雨水较少。春天来到后,东南方海洋上的暖温空气开始活跃。冷暖空气碰撞发生冲突,就会形成阴雨绵绵的天气。清明时节,冷暖空气正好在江南地区的上空来来往往,十分忙碌,所以经常出现细雨纷纷的天气

答案

参考答案:C

解析: 一块成熟的雷雨云,其顶部温度可以低至-40℃(约1万米以上的高度),而云底部的温度却在10℃以上。由于云体在垂直方向上跨过了这么宽的温度范围,因而云中水汽凝结物的状态就很不一样。云中有水,经过冷却凝结成水滴、雪品、冰品等。C项说法不全面,雷雨云除了形成水滴外,还有雪品、冰品等。故选C。
