Since the middle of 65438 10, there has been a large range of rain and snow weather in southern China. The statistical map of snow cover in southern China and other provinces and cities made by multi-source satellite snow monitoring information shows that from 26th to 29th, many provinces in southern China maintained large-scale snow cover, and Henan, Anhui, Hubei, Shanghai, Jiangsu, Hunan, Chongqing, Shaanxi and other provinces and cities accounted for more than 70% of the province's urban area, among which Henan, Anhui, Hubei, Shanghai, Jiangsu and Shaanxi accounted for more than 70% of the province's urban area. The snow area in Guizhou, Jiangxi, Zhejiang, Sichuan and other provinces accounts for about 25%-45%.
From the snow monitoring map of multi-source satellite remote sensing on June 29th, 65438, it can be seen that there is snow in most parts of the south of the Yangtze River, most parts of Huanghuai, Jianghuai, Jianghan, northwest and east, northwest, western North China, Inner Mongolia and northeast China.
From the estimated map of snow thickness made by clear sky data from satellite remote sensing on October 29th, 65438, it can be seen that the snow thickness in central and southern Henan, northern Anhui, northern Jiangsu, northern Hubei, northwestern Hunan and southern Shandong exceeds 10 cm, and quite a few areas exceed 20cm.
From the snow monitoring map of polar-orbiting meteorological satellite on June 5438+1October 30 (pictured), it can be seen that there is snow in most parts of Henan, northern Anhui, northern Jiangsu, most parts of Hubei, Shaanxi and Shanxi. Southern Anhui, southern Jiangsu, Hunan, Zhejiang, Jiangxi, Guizhou, Sichuan and other places are covered by clouds.
Using satellite remote sensing 65438+129 October snow monitoring information, we can see that railways, highways, airports and other traffic and shipping in Henan, Anhui and other provinces are in snow-covered areas, including Beijing-Guangzhou Railway, Beijing-Zhuhai Expressway and other traffic arteries. At the same time, we can see that some airports are shrouded in fog.
