A powerful cold wave is gripping large parts of China this week, driving temperatures sharply lower and pushing the freezing line steadily south, according to the National Meteorological Center.

据国家气象中心称，本周一股强劲寒潮正席卷中国大部分地区，气温急剧下降，冰冻线持续向南推进。

The center continued to issue blue alerts — the lowest of a four-tiered color-coded warning system — for a cold wave and strong winds on Tuesday morning, forecasting that the cold air will keep moving east and south through Wednesday.

气象中心周二上午继续针对寒潮和大风发布蓝色预警——这是四级颜色编码预警系统中的最低级别——并预测冷空气将持续向东和向南移动至周三。

Yang Shunan, chief forecaster at the center, said the cold wave has already gripped the entire northern part of the country and continues to push south.

气象中心首席预报员杨舒楠表示，这波寒潮已覆盖全国北方地区，并持续向南推进。

As of Tuesday afternoon, temperatures in the Inner Mongolia autonomous region, Northeast China and North China had fallen by 6 to 10 C, with some areas recording drops of 12 to 14 C. These regions, along with the Shandong and Liaodong peninsulas, have also recorded winds of up to 39 kilometers per hour, Yang said.

截至周二下午，内蒙古自治区、东北地区和华北地区气温普遍下降6至10摄氏度，部分地区降温幅度达12至14摄氏度。杨舒楠表示，这些地区以及山东半岛和辽东半岛还出现了时速达39公里的强风。

On Tuesday, Beijing and Tianjin recorded their coldest morning of the second half of the year at around minus 5 C, while Changchun in Jilin province, Shenyang in Liaoning province and Shijiazhuang in Hebei province also hit new seasonal lows.

周二，北京和天津录得今年下半年最低气温，约为零下5摄氏度；吉林省长春市、辽宁省沈阳市和河北省石家庄市也创下本季新低。

The cold wave is set to keep pressing south over the next two days, bringing the coldest conditions of the season so far to large parts of central and eastern China. In some areas of Jiangsu, Anhui and Zhejiang provinces, temperatures are expected to plunge by more than 10 C, with wind chills exacerbating the cold conditions.

未来两天，寒潮将继续向南推进，给中国中部和东部大部地区带来今冬迄今最严寒的天气。江苏、安徽和浙江部分地区气温预计将骤降10摄氏度以上，寒风将使体感温度进一步降低。

"The most notable features of this cold wave are its complex weather impacts and the significant temperature plunge," Yang said.

杨舒楠表示：“此轮寒潮最显著的特征在于其复杂的气象影响和显著的降温幅度。”

In addition to strong winds and plummeting temperatures, sand and dust storms were reported in parts of Inner Mongolia and North China in the early stages of the cold air outbreak.

在冷空气来袭初期，除强风和气温骤降外，内蒙古和华北部分地区还出现了沙尘暴。

Unlike the cold wave in mid-November, which took a more westerly track and brought sharper temperature drops to southern and western regions, the current system is tracking slightly farther north, resulting in the strongest cooling being concentrated north of the Yangtze River, she said.

杨舒楠指出，与11月中旬那场偏西路径、导致南方和西部地区气温骤降的冷空气不同，当前这股冷空气路径略偏北，因此强降温主要集中在长江以北地区。

On Wednesday morning, the nation's coldest regions will be in parts of the northeast, northwest and North China, according to the center.

气象中心称，周三上午，全国最寒冷的地区将出现在东北、西北和华北的部分地区。

Minimum temperatures below minus 10 C are forecast across more than 10 provincial-level regions, including the Xinjiang Uygur autonomous region as well as the provinces of Qinghai, Gansu and Hebei.

预计新疆维吾尔自治区、青海省、甘肃省、河北省等十余个省级行政区最低气温将低于零下10摄氏度。

Major northeastern cities such as Harbin and Changchun may see temperatures dip below minus 20 C for the first time this season. Forecasters advise commuters and students to bundle up with hats, gloves and scarves to avoid frostbite.

哈尔滨、长春等东北主要城市的气温可能在本季首次跌破零下20摄氏度。气象预报员建议通勤者和学生做好保暖措施，戴好帽子、手套和围巾，以防冻伤。

By Thursday, the freezing line will reach its southernmost point during this cold spell, extending into parts of Zhejiang, Anhui and Hubei. The cold wave is expected to weaken and come to an end from late Wednesday into Thursday night, Yang said.

到周四，冻线将达到此轮寒潮的南端极限，延伸至浙江、安徽和湖北部分地区。杨舒楠表示，预计寒潮将于周三晚至周四夜间逐渐减弱并结束。
