新一轮冷空气即将影响我国 北方多地气温将创新低

新一轮冷空气将从10月15日起影响中国，北方地区气温面临显著下降1。降温过后，北方大部最高气温将不足20℃，其中西北、华北北部、东北等地最高气温将不足10℃1。

本轮冷空气影响范围广泛，16日至19日将自西向东影响长江中下游及以北大部地区1。新疆北部、华北、东北地区、黄淮、江淮、江汉、江南西部和北部等地将先后出现4至6℃的降温，局地降幅可达8℃以上1。到21日早晨，西北、华北大部、东北地区最低气温将不足10℃，其中西北地区大部、华北北部、东北北部等地最低气温将不足0℃1。

值得关注的是，本轮冷空气将推动多个城市气温创下半年新低1。呼和浩特、乌鲁木齐、西宁的最高气温将在今年下半年首次降至10℃或以下，天津、济南也将首次降至20℃以下1。同时，西北地区东部、华北、东北、黄淮、江淮、江汉、江南北部及重庆等地将出现中到大雨，局地可能发生暴雨或大暴雨1，加快北方多地的入冬进程。

A new cold air mass will begin affecting China starting October 15th, bringing significant temperature drops and widespread precipitation across the nation 1. Following the cooling period, maximum temperatures across most northern regions will fall below 20°C, with northwestern, northern North China Plain, and northeastern areas experiencing highs below 10°C 1.

The cold front will advance eastward from October 16th to 19th, impacting areas from the middle and lower Yangtze River northward 1. Xinjiang's northern sections, North China Plain, northeastern regions, the Yellow River and Huai River basins, and western and northern portions of the Yangtze River basin will experience temperature drops of 4 to 6°C, with some areas seeing declines exceeding 8°C 1. By the morning of October 21st, minimum temperatures in northwestern regions, most of North China Plain, and northern northeast China will fall below 0°C, while broader northwest and central regions will dip below 10°C 1.

Several major cities will record their first sub-seasonal temperature milestones. Hohhot, Urumqi, and Xining will see maximum temperatures drop to 10°C or below for the first time in the second half of this year, while Tianjin and Jinan will experience their first maximum temperatures below 20°C 1. The cold front will also be accompanied by substantial precipitation, with medium to heavy rain expected across northwestern China, North China Plain, northeastern areas, the Yellow-Huai basins, the middle Yangtze River region, northern Yangtze River basin, and Chongqing, with some localities facing downpours or torrential rainfall 1.
