“Rare Snow” in Shanghai

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…

    So what’s that Koeppen-Geiger map looking like now? Are there any boundary movements between climate types since AGW kicked off? If not, there is no climate change.

    If you do a screen grab of :

    Right now you can see cold air pouring out of eastern China along side the Korean Pennisula down toward Shanghai.

    At 100k ft altitude there is strong westerly flow out of central Chinese mainland

    With temperatures in the high 20’s to low 30’s (deg F)

    That is insane! Standing on a slippery bus, holding electrical cables?

    I hope that man was paid very well!

    Rhoda Klapp,
    Right on! I’ve been making a similar point for 10 years on blogs such as this. (Okay; 9+ years)
    The person that started the simple temperature change as “global warming/climate change” ought to be shot. Oh, I’m not to say that, I guess.

    For those that are unaware; Köppen began with plants and looked for ecotones, although not using this term. Numbers are easier and cheaper, so temperature and precipitation entered. But, vegetation integrates climate and can’t be fooled, nor adjusted.

    Looks like Japan is involved too:


    Rare and heavy snow sparks chaos in Japanese capital.

    Tokyo’s ambulance service has experienced its busiest day in more than 80 years, officials said

    “We think the combination of influenza, heavy snow and cold weather contributed to the record high number,” said a spokesman for the Tokyo fire department, which runs the ambulance service.

    The mercury in Tokyo dropped to -4C (25F), the coldest in 48 years, according to Japan’s Meteorological Agency.

    A rare heavy blanket of snow in Tokyo on Tuesday left thousands of travelers stranded and scores injured.

    Japan’s weather agency recorded as much as 23 cm (9.2 inches) of snow in parts of Tokyo.

    On the same day, the temperatures in Hokkaido, well accustomed to cold winters, dropped to -31.3 °C (-24.3 °F). Some parts of Hokkaido registered record lows.

    And the government warned the glacial conditions would continue.

    @John, no plants do not integrate climate. They must survive and thrive in whatever the local weather is at every point in time and at a point in space on the this rock we call Earth. Plants integrate weather.

  7. p.g.sharrow says:

    Plants require energy to carry out their needed biological functions. Sunlight, carbon dioxide and water to create carbohydrates that they need to function. Soil temperatures and air temperatures at night must be over 53F degrees or the plants must burn carbs to warm themselves. Cold nights or cold soils can cause exhaustion or lack of growth, no matter what the daytime temperatures or amount of sunlight…pg

    @Per Integration:

    Since climate is supposedly integral weather, the argument over plants integrating weather vs climate is just first or second integral…

    The reality is that plants, like animals, have limits. Limits on water needed. Limits on cold endured. Limits on heat to kill. etc. The Koeppen Climate zones came from that recognition. That’s why they matter.

    In my yard is a tomato vine. It is presently 1/2 dead and browned from frost. A couple of days ago I picked a few ripe “cherry tomatoes” from the other half. It is in a slightly sunnier area and closer to the shed that gets afternoon solar warmth and light. That plant is telling me it is ALMOST frozen out… I’m on the edge of “frost hardy” vs “frost killed”. (Next month it will be all frost killed).

    So to ask if the Koeppen zones have changed IS to ask a series of questions in one: Has the frost line moved? Has the tree line moved? Has the first / last frost date changed significantly? Has the water changes (higher or lower)?

    FWIW, there was a recent shift of the Koeppen zone map. Not much at all, and well inside what would fit in the cyclical changes from the ’70s to now. As we are now in a cooling 1/2 phase, I fully expect to return to the older map in about a decade when it is clear the old map frost kill zones are applying again… IMHO the changes were largely politically inspired by zealots (or perhaps idiots) and with deliberate ignorance of the 60 year cycles.

    Late to the party, but…..

    I live in northern Tohoku. Winter came early (the snow has been lying since November rather than late December when it usually starts). By yesterday (Friday) it was shoulder deep on my garage roof and something had to be done. The garage (like most roofs in heavy snow areas) is rated at 2 metres. I spent 3 1/2 hours taking a 120cm cut off, and dumping the snow down the magic hole.

    Good move. This morning dawned to a 40cm overnight snowfall. Starting a 8 a.m.it took me until 9:30 to get the shop front open and another hour to clear the carpark. A break to change clothes, rest, and an hour’s teaching saw me outside by 11 to tidy up. The dang Yukios (snow pusher) broke its throttle cable and i’m back to the old method. It being Saturday there’s no chance to replace the cable before late Monday.

    Today, all my neighbours were either up on the roof skimming snow, or on the ground scooping snow down the magic hole. FWIW, my town averages about 10 metres of snow every winter. In 20012/13 winter we had over 16 metres of snow.

    Snow and cold all over the planet. Watch the daily video reports from Adapt 2030, Oppenheimer Ranch Project and The Watchers who collect info from all over the world.
    And also have a look at the latest CIMP6 solar forcing dataset that clearly shows the upcoming Eddy Minimum to ruin this entire century. https://scontent-ort2-2.xx.fbcdn.net/v/t1.0-9/26993800_1782578218460576_5228760927433785453_n.jpg?oh=288bba30c5884698ae1bbca87fab1857&oe=5AF5A7C6

    Global Warming is dead. Now we have to sideline up the sick pack of apparatchiks that baked who baked us this poisonous cake.

    Snow, hail and cold events in exotic places lately. Sahara, Morocco, Algeria, Saudi Arabia, Oman, Viethnam, Myanmar (where they dressed uo there elephants with knitted woolen covers to protect them from the cold, India and Bangladesh where children and elderly died from the cold. Also cold spells in Mexico affecting crops and crop yields and some regions in South America. All these events took place this month. In the mean time MSM is pushing all time warmth records for this month although we’re in a very small band of green between the North Sea and the Atlantic and the terrible cold that has settled over Northern Europe, the East and the Alps.
    We’re just lucky
