据中央气象台数据显示，由于14日强冷空气的到来，全国22个城市经历断崖式”降温。中东部大部分地区降温6-10摄氏度。10月17日，北京气温受寒潮影响降到0摄氏度以下，创下10月中旬气温最低值。气象部门也发布寒潮预警，建议公众针对寒冷天气和强劲大风采取预防措施，同时建议交警部门预备应对道路结冰等情况。
According to the National Meteorological Center, due to a strong cold wave that hit China on Oct 14, 22 cities have seen cliff-like drops in temperatures. Temperatures in most of the central and eastern regions across the country had dropped by at least 6 to 10 C. For example, the cold wave drove temperatures in Beijing below 0 C on Oct 17, setting a record low for the mid-October period. China’s meteorological authority also issued alerts for the cold wave, advising the public to take precautions against the cold weather and strong winds. It also suggested traffic and police authorities prepare for icy road conditions.
表示温度下降除了drop，还可以用fall，decline，plunge。表示“寒潮”可以说cold front、cold snap、cold wave、cold spell。
