中东部多地将开启回暖 昼夜温差加大江南多地可超15℃

Group 1 - A weak cold air mass is currently affecting northern China, leading to noticeable temperature drops in some areas, particularly in Inner Mongolia where snowfall is also occurring [1] - The cold air will continue to impact the northwest region with temperature decreases of 2 to 6 degrees Celsius, while the south will begin to warm up as rain and snow diminish [2] - After the cold air influence ends, most of central and eastern China will experience warming, with daytime temperatures in the lower reaches of the Yangtze River expected to exceed 15 degrees Celsius [2] Group 2 - Despite the warming trend during the day, nighttime temperatures will remain low, resulting in significant diurnal temperature variations, with some areas in Hubei, Hunan, Jiangxi, and Zhejiang experiencing differences exceeding 15 degrees Celsius [2] - In major cities like Changsha, daytime highs will rise above 15 degrees Celsius, while nighttime lows will hover around 0 degrees Celsius, indicating a "one day, two seasons" scenario [2] - Recommendations for dressing in such variable temperatures include layering with moisture-wicking inner layers, warm sweaters or fleece for mid-layers, and waterproof, windproof outer layers to ensure comfort and warmth [2]
