In January 2024, many regions across China experienced unusually high temperatures, with cities such as Nanjing and Hefei recording record-breaking highs for the month. According to meteorological data, Nanjing reached a maximum temperature of 22.3°C on a January day, while Hefei hit 23.1°C—both significantly above the long-term average for January and setting new historical records for the month.Experts attribute this anomalous warming primarily to a strong influx of warm, moist air from the southwest and an unusually northward extension of the subtropical high-pressure system, combined with weaker-than-normal cold air activity. These conditions led to prolonged sunny and clear weather across southern China, allowing temperatures to rise rapidly. While the ‘warm winter’ may feel pleasant in the short term, it could disrupt agriculture, ecosystems, and energy management. For instance, some overwintering crops might sprout prematurely due to elevated temperatures, increasing their vulnerability to frost damage later. Additionally, the altered seasonal cues may confuse public health preparedness.Meteorological authorities caution that despite the current warmth, winter is not yet over, and sudden cold snaps or cold waves could still occur. The public is advised to stay updated with weather forecasts and adjust daily routines accordingly to mitigate health risks associated with rapid temperature fluctuations.
2024年1月，中国多地遭遇异常高温天气，其中南京、合肥等城市气温显著偏高，打破当地1月历史最高气温纪录。据气象部门监测，南京1月某日最高气温达22.3℃，合肥则达到23.1℃，均远超常年同期平均水平，并刷新有气象记录以来1月的最高值。专家分析指出，此次异常升温主要受强盛的西南暖湿气流和副热带高压异常北抬影响，加上冷空气活动偏弱，导致南方多地持续晴朗、日照充足，气温快速攀升。这种‘暖冬’现象虽带来短暂舒适，但也可能对农业、生态系统及能源调度造成一定影响。例如，部分越冬作物可能因温度过高而提前返青，增加冻害风险；同时，公众对季节变化的感知错乱也可能影响健康防护。气象部门提醒，尽管短期气温偏高，但冬季尚未结束，仍需警惕后续可能出现的剧烈降温或寒潮。公众应关注最新天气预报，合理安排出行与生活，避免因气温剧烈波动引发健康问题。
