The Chinese paddlefish (psephurus gladius) in Yangtze river extinct... https://www.nationalgeographic.com/animals/2020/01/chinese-paddlefish-one-of-largest-fish-extinct/ I can't tell the impact on fishery in terms of economics... I think there have been researches but I didn't focus on it.

The Three Gorges dam is mainly built for power and control the flood threat in summer. The starting point of the South-North water transfer project is Danjiangkou reservoir located at northwest Hubei. Southern China have rather enough rainfall in winter and the early spring rain season start at March. (attached: January and July mean precipitation in mm)

Here is another map of "annual average maximum snow depth"(not snowfall) based on all stations made by us. The snowfall of the western parts of China is too difficult to estimate so we haven't done it yet. * in centimeters ** shown all claimed territory. Some famous snowy attractions and towns in China (honestly not comparable with Japan, Russia, Northern Europe, Canada, and USA) : Kanas Lake, Altay Prefecture, Xinjiang - estimated 150 inches (4 meters) of annual snowfall Altay City, Xinjiang - estimated 70 inches (1.8 meters) of snowfall Nyalam County, Xigaze, Tibet - estimated 70 inches (1.8 meters) of annual snowfall, with record maximum snow depth of 2.30 meters which made of two snow events. - snowiest national observation station (WMO ID: 55655). Xuexiang ("snow town") National Forest Park, Changting township, Heilongjiang - estimated 80 inches (2 meters) of snowfall Heaven Lake of Changbai/Paektu Mountain, Jilin - estimated 100 inches (2.5 meters) of snowfall Wendeng District of Weihai City, Shandong - estimated 20 inches (0.5 meters) of snowfall, the snowiest town south of the Great Wall in eastern China.

Well, the vegetation in Beijing is temperate deciduous forest (and for the entire North China Plain), with 580mm (23 inches) rainfall annually mostly in summer, enough for trees but far from enough for people with its huge population .

Thank you for sharing this! One problem is, before 2010, stations in China that of very high latitude and have stable snow cover season only measure snow depth after new snow drops, but we wouldn't know the depth value before that and hence cannot calculate the snowfall. I try to obtain the 2010-present value and then to get liquid-to-snow ratio and published climatology (precipitation, temperature, snowy days, etc) to convert it to an estimated 20-30 year mean value.

I just drew sketch maps of snowfall in Nov, Dec, Jan, Feb, and Mar, not as high-quality as the annual map though.

Hi etudiant, Harbin only receives around 4.5mm(0.18 inches) of precipitation / 2 inches of snow in January, which is not high, but this city have nearly six months for snow, and the moisture condition would be much better in Nov and Mar. After all, Harbin locates farther east than 120E and therefore sometimes ahead the trough and have more chance to experience extratropical cyclone(especially in Nov, Dec, and Mar, when the westerlies are more active (in wavy activity)), which bring the moisture from the Sea of Japan, Yellow Sea and Bohai Sea. Harbin just received 10 inches in one snow storm last month.

I am from China, and I think eastern America and eastern China are (most) comparable in climate, both have continental humid and subtropical humid climate (the difference is monsoon). We observe snow depth once a day at 00UTC (sometimes more than once though) , but do not have statistics. I don't have data from all stations but some of them.

What is typical in January...

Thank you! I am a weather enthusiast from Beijing and now studying meteorology in Raleigh, North Carolina. It is because they don't measure snowfall as an accmulation of new snow - the concept of snowfall does not exist in our meteorology, instead we only count snowy days, precipitation, maximum snow depth and snow-covered days for climatology. (I didn't see that kind of map of Europe either - I did see the USA, Russia, and Japan version) Northern China see much lesser snow compared with the same latitude in US, because the Mongolia high surpresses extratropical storm activity and the Tibetan Plateau locks the phase of westerlies. However, southern China - 33N or less are snowier than the same latitude in US - the persistent heavy snow (and ice) happened in January 2008 almost shut down half of the southern China for nearly one month. The western parts of China might be a little bit different - Altay Prefecture of Xinjiang is the most snowy region in China, of which annual snowfall range from 50 to more than 150 inches (the Kanas Lake) as I estimate.

I guess it's nice to be compared with the US version

You won't find it elsewhere! China Meteorology Agency does not give official snowfall statistics. The contours are in centimeters, so 1 is 0.4 inches, 2.5 is 1 inch, 5 is 2 inches, 10 is 4 inches, 15 is 6 inches, 20 is 8 inches, 30 is 12 inches, 50 is 20 inches, 70 is 28 inches, and 100 is 40 inches.
