选项 A、a tornado in Edmonton, Alberta
B、what’s a "Nowcast"
C、the disadvantage of conventional computer models of the weather forecast

答案D
解析 主题归纳。文中一开始讲述了某次龙卷风造成的损失,指出传统的计算机天气预测模式由于没有详细的天气情况数据而不能对类似于龙卷风的暴风雨做出及时的预报。直到最近,由于高科技的发展解决了人们收集天气数据时的种种问题,才使得Nowcast这种准确、及时的天气预报成为现实。因此,文章主要讲述天气预报方面的一大突破(breakthrough)。
