Group 1 - The 2026 Spring Festival travel season has begun, with a predicted total of 9.5 billion trips, setting a new historical record for inter-regional mobility during this period [1] - The first week of the Spring Festival will experience fluctuating temperatures, with a warm-up followed by a significant drop due to a new cold air mass arriving around February 5 [3][4] - The northern regions will face strong winds and temperature drops, with maximum temperature decreases expected to reach around 10°C, while southern regions will experience widespread rain [3][4] Group 2 - The combination of cold air and warm moist air will lead to extensive rain in southern regions during the latter half of the first week, particularly affecting travel conditions [4] - Areas such as Xinjiang, Gansu, and parts of Inner Mongolia will have favorable weather for travel, but significant temperature differences between day and night will require travelers to dress appropriately [4] - Safety guidelines for travel during the Spring Festival emphasize the risks associated with winter weather, including slippery roads and the importance of wearing appropriate footwear and clothing [5]

Core Viewpoint - The weather during the Spring Festival travel season in February 2026 will be influenced by multiple cold air processes, with varying temperatures and precipitation across different regions of China. Group 1: Cold Air Processes - Four cold air processes will impact China in February, with varying intensities: moderate in early February, strong in mid-February, moderate again in mid-February, and weak towards the end of the month [1]. - The average temperature in February will be lower by 0.5 to 1°C in northern parts of North China, western Northeast China, northwestern Tibet, and northern Xinjiang, while the rest of the country will see temperatures close to or above normal [1]. Group 2: Precipitation and Weather Risks - The eastern and central regions will experience more precipitation in the north than in the south, with potential for low-temperature rain and snow events [2]. - Northeast China, northern North China, and northern Xinjiang will have temperatures close to or below normal with increased precipitation, leading to risks of strong cooling, strong winds, and heavy snowfall [2][3]. Group 3: Regional Temperature and Drought Conditions - Southeastern East China, southern Central China, eastern South China, and western Southwest China will experience higher temperatures and continued low precipitation, which may lead to meteorological drought conditions [4]. Group 4: Upcoming Weather Trends - A significant warming trend will last for nearly five days, with temperatures in many regions expected to rise by over 10°C, and some areas exceeding 15°C [5][6]. - A new cold air mass will arrive on February 5, bringing a temperature drop of 4 to 8°C, with localized areas experiencing drops of 10 to 12°C, along with light to moderate rain in various regions [8][10].
