Heard it on Fance 24 so it must be true…
They were pointing out a lot of “Rare Snow in Shanghai”. The wiki says they get one or two days a year:
Shanghai has a humid subtropical climate (Köppen Cfa) and experiences four distinct seasons. Winters are chilly and damp, with northwesterly winds from Siberia can cause nighttime temperatures to drop below freezing, although most years there are only one or two days of snowfall. Summers are hot and humid, with an average of 8.7 days exceeding 35 °C (95 °F) annually; occasional downpours or freak thunderstorms can be expected. The city is also susceptible to typhoons in summer and the beginning of autumn, none of which in recent years has caused considerable damage. The most pleasant seasons are spring, although changeable and often rainy, and autumn, which is generally sunny and dry. The city averages 4.2 °C (39.6 °F) in January and 27.9 °C (82.2 °F) in July, for an annual mean of 16.1 °C (61.0 °F). With monthly percent possible sunshine ranging from 34% in March to 54% in August, the city receives 1,895 hours of bright sunshine annually. Extremes since 1951 have ranged from −10.1 °C (14 °F) on 31 January 1977 (unofficial record of −12.1 °C (10 °F) was set on 19 January 1893) to 39.9 °C (104 °F) on 6 and 8 August 2013. A highest record of 40.9 °C (106 °F) was registered in Xujiahui, a downtown station on 21 July 2017.
Humid Subtropical sound more like Florida, then again, we’ve had snow in Florida this year too.
This news article with lots and lots of photos seems to think there was way more than usual for more days than usual.
Stunning Photos of Shanghai Covered in Snow
By Bridget O’Donnell, January 25, 2018
Shanghai was treated to rare sighting of snow this week, as a cold front hit the city starting Wednesday.
The first snowflakes were spotted at around 3pm Wednesday afternoon. The light flurries continued through the evening and into Thursday. At 12.43pm this afternoon, the city issued a yellow blizzard alert as the snowfall became heavier.
Somehow “Blizzard Alert” does not sound like a light dusting on a day or two…
In the teaser block at the bottom is a link to another article that implies it isn’t over for a while. How long TBD:
Shanghai Set for Snow Next Week
Just when you thought it was finally getting warmer.
It looks like Central China got a big wallop and it spilled over to the coast. Probably time to look at a snow map of the globe compared to norms. This is from a couple of weeks ago:
Flight Delays, Train Cancellations as Deadly Blizzards Hit China
By That’s, January 4, 2018
At least one person has been killed and several other injured by heavy snowfall that hit central China this week.
The South China Morning Post reports that one person was confirmed dead and 20 injured after snow caused tree branches and roofs to collapse in Hefei, Anhui Province this morning. Images of a police officer in the city standing atop a bus and holding up a cable to let cars pass by went viral.
The blizzards were expected to hit parts of Shanxi, Shaanxi, Henan, Shandong, Anhui and Jiangsu on Wednesday and Thursday (through the evening).
The weather has also forced schools, major roads and transportation hubs to close as some areas have been forecasted to receive up to 30 centimeters of snow.
At least three airports (Hefei Xinqiao International Airport and Fuyang Xiguan Airport in Anhui, and Jining Qufu Airport in Shandong) suspended operations today because of the snow. Nine other airports — including those in Beijing, Xi’an, Hefei, Zhengzhou and Nanjing — are experiencing serious delays as runways have been shut down.
Lots of photos in that one too.
To me, it looks like the same kind of Mobile Arctic High air mass that’s dragging arctic temperatures down the Eastern USA. Cold (very cold) blobs from the Arctic headed south pushing warmer air up in other ares (like the West side of the USA) for their turn in the ice box. Except there isn’t much in Europe / Asia that’s warm right now…
