Group 1 - The core viewpoint indicates that while cold air will frequently affect the weather, temperatures in North China and southern regions will generally rise, with maximum temperatures significantly higher than usual, particularly in the Yangtze River basin where many areas will see highs around 20°C [1][7] - The temperature drop will continue to move east and south, affecting Northeast, East North China, Huanghuai, and Jianghuai regions, with slight decreases also expected in Jiangnan and southeastern South China [2] - Over the next ten days, cold air will frequently impact the weather, but its intensity will be relatively weak and mainly affect northern areas, with most of the country experiencing higher than normal temperatures [3] Group 2 - In Northeast China, cold air and frequent snowfall will lead to temperatures being lower than the historical average for this time of year, with cities like Changchun and Harbin experiencing maximum temperatures below -10°C and -18°C respectively [5] - For North China and southern regions, temperatures will fluctuate and rise, with significant increases expected from December 12 to 16, particularly in maximum temperatures, which will reach around 20°C in cities like Hefei, Wuhan, Nanjing, Hangzhou, Changsha, and Nanchang [7] - Despite the warming trend, nighttime temperatures will not rise significantly, leading to a large diurnal temperature range exceeding 15°C in many areas, with some locations surpassing 20°C, necessitating attention to warmth during early morning and evening outings [7] Group 3 - Alongside the temperature increases, most regions in China will maintain a dry weather pattern with little precipitation, and even in the south, afternoon humidity levels will drop below 40% or even 30% in some areas [8] - Due to the lack of rainfall, certain areas in southern Fujian, southeastern Jiangxi, eastern and southern Guangdong, and southeastern Guangxi will face high forest fire risk levels, highlighting the need for fire safety precautions [8]
