【1】要监测该“炸弹气旋”的位置,需运用的地理信息技术是( )
A. 卫星遥感技术B. 地理信息系统
C. 全球定位系统D. 航空遥感技术
【2】关于此次“炸弹气旋”说法正确的是( )
A. 属海洋灾害B. 给美国旧金山带来狂风、酷寒和暴风雪
C. 是热带气旋D. 北极极冷空气与海洋暖湿空气相遇而成
【答案】
【1】A
【2】D
【解析】
【1】遥感技术是在距离地球一定距离的飞机、飞船、卫星上,使用光学仪器和电子仪器,接收地面物体发射或反射的电磁波信号,以图像胶片或数据磁带形式记录下来,传送到地面,最后通过分析,揭示出物体的特征、性质以及变化。因此对“炸弹气旋”的监测,需要的是GIS技术,故选A。
【2】由材料分析可知,“炸弹气旋”指发生在中高纬度洋面上、强烈迅速发展的锋面爆发性气旋,因该属于气象灾害,A错误;由材料可知,该“炸弹气旋” 主要分布在美国东海岸上空,对旧金山影响不到,B错误;“炸弹气旋” 主要是北极极冷空气与海洋暖湿空气相遇而成的,并非热带气旋,D正确,C错误。故选D。
