Core Viewpoint - The article discusses the ongoing foggy weather conditions affecting several regions in China, particularly in Beijing, Tianjin, and Hebei, with visibility dropping below 200 meters in some areas. The article also explores the reasons behind the recurrence of fog and its expected duration. Group 1: Weather Warnings and Conditions - The Central Meteorological Observatory issued a yellow fog warning, predicting dense fog in southeastern Beijing, central Tianjin, central Hebei, western and southern Shandong, northern Jiangsu, northern Anhui, and central Hunan, with visibility potentially below 200 meters [1][3] - The recent fog events are attributed to a pattern of cold air activity interspersed with moist conditions, which has led to three significant fog occurrences since autumn, primarily in the Beijing-Tianjin-Hebei region [3][5] Group 2: Impact on Transportation - Foggy weather significantly impacts transportation, particularly on highways where "tuanwu" (group fog) is common, especially in the North China Plain, Jiangsu, and Anhui regions [7] - The latest forecast indicates that the current foggy conditions will persist until the 8th, with a cold air front expected to move eastward on the 9th, gradually reducing the fog [9]

Core Points - The Central Meteorological Observatory has issued a yellow fog warning, predicting dense fog with visibility below 200 meters in several regions including southeastern Beijing, central Tianjin, central Hebei, western and southern Shandong, northern Jiangsu, northern Anhui, and central Hunan [1][3] - The recent fog events are attributed to specific weather patterns, particularly the dry upper air and moist lower air, which facilitate fog formation [4] - The current foggy conditions are expected to persist until the 8th, with a cold air mass moving in on the 9th, leading to a gradual reduction of fog in the central and eastern regions [7] Weather Impact - The fog significantly affects transportation, especially on highways where "tuanwu" (fog patches) are common, particularly in the North China Plain, Jiangsu, and Anhui [5] - There have been three major fog events since the beginning of autumn, primarily affecting the Beijing-Tianjin-Hebei region and surrounding areas [3]

Weather Alerts - The Central Meteorological Observatory issued a blue rainstorm warning, predicting heavy rain in regions including southern Shaanxi, northeastern Sichuan, and most of Chongqing from October 12, 08:00 to October 13, 08:00, with local areas experiencing extreme rainfall of 100-120 mm [3][5] - The warning includes potential short-term heavy rainfall with maximum hourly precipitation of 20-30 mm, and localized areas may exceed 50 mm, along with thunderstorms and strong winds [3][5] Typhoon Update - Typhoon "Nakiri," the 23rd typhoon of the year, has intensified from a tropical storm to a strong tropical storm as of October 11, with maximum wind speeds of 28 m/s and a minimum central pressure of 982 hPa [7][8] - The typhoon is expected to move northeast at a speed of 25-30 km/h, gradually weakening and transitioning into a temperate cyclone by October 14 [8] Air Quality and Meteorological Conditions - Most regions in the country are experiencing favorable atmospheric diffusion conditions, with no significant haze expected; however, from October 13 to 16, some areas in central and southern regions may experience short-term haze [11][12] - Specific regions such as the Yangtze River Delta and the Fenwei Plain are forecasted to have good atmospheric conditions with no significant haze [13][14] - The central and southwestern parts of Hunan may see light to moderate haze on October 12, but conditions are expected to improve later [15]
