Earliest ice formation on Korean river in 71 years

Unusual cold wave triggers earliest ice formation on the Han River since December 12, 1946.

16 Dec 2017 – A five-day cold spell has led to ice formation on the Han River one month earlier than expected. The ice formation was observed at the Han River Bridge at dawn yesterday, according to the Korea Meteorological Administration.

Freezing of the Han River occurred 29 days earlier than the usual (Jan 13) and even 42 days earlier than last year (Jan 26).

Usually, ice formation on the Han River occurs if the low morning temperature in Seoul falls below minus 10 degrees Celsius for three consecutive days and remains below zero during the day, and that is exactly what happened.

The low temperatures of the morning in Seoul from Monday to Thursday were minus 11 C, minus 12.3 C, minus 12 C and minus 11.2 C. The sub-zero temperatures continued during the days.

  1. Yes, it is cold here in Korea these days. There was a cold spell in mid-November that lasted 7 days and earlier in December we had 8 days where either the daily low was lower than normal, the daily high was lower than normal, or both.

  2. With nearly 83 inches, this place is NY’s snowiest

    ALBANY — Winter has yet to officially start, but snow is already piling up in some parts of upstate New York.

    According to the National Weather Service, the areas with the most snow are in Oswego and Lewis counties — which get clobbered each year with snow drifting across the eastern edge of Lake Ontario.

    And it’s the usual places: the tiny town of Redfield in Oswego County is leading the state with 82.6 inches of snow as of Friday.

    So at this rate, Redfield is on pace for its second straight national recognition: Last year it won the USA Today Network’s first annual Golden Snowdrift Award after getting 350.5 inches of snow — which equals more than 29 feet.

  3. The sun is blank, NASA data shows it to be dimming

    As the sun gets successively more blank with each day, due to lack of sunspots, it is also dimming. According to data from NASA’s Spaceweather, so far in 2017, 96 days (27%) of the days observing the sun have been without sunspots.

    Across the entire electromagnetic spectrum, the sun’s output has dropped nearly 0.1% compared to the Solar Maximum of 2012-2014.

  4. Cold spells predicted over upper Thailand 17 Dec 2017
    With a strong high-pressure area covering upper Thailand and the South China Sea, the temperature will drop by 3-5 degree Celcius in the northern and central parts of the country – including Bangkok and its vicinity – during Dec 17-18, the Thai Meteorological Department said in its 11am announcement on Sunday. Mountaintops will be very cold with isolated frost.
    During Dec 19-21, another strong high-pressure area from China will reach upper Thailand. As a result, cold spells will continue and the temperature will decrease further by 2-3 degree Celcius.

  5. In case I didn’t mention it, when it was snowing in Mexico, or shortly thereafter, there was also the earliest Northeaster that I can remember for a while that was all snow to Washington DC, I believe, all the way up the Northeast Coast. 4-8 inches.
