It was found that the Han River did not freeze in this winter, when it was exceptionally dry and there was no rain.
The Korea Meteorological Administration announced today (15th) that no ice was observed in the Han River from December 2021 to February 2022.
It is the ninth time that the Han River has not frozen since the first observation of ice in 1906.
In the observation of freezing on the Hangang River, a band shape is observed in the vicinity of 100m upstream of the second and fourth piers of the Hangang Bridge.
If the part is completely frozen and you can't see the river, it is judged that the Han River is frozen.
Some ice was observed at the observation site this winter, but it was not recognized as ice because it was not completely covered with ice.
The Korea Meteorological Administration analyzed the Seoul temperature from 5 days before the freezing day of the Han River to the freezing day for the past 7 years.
The temperature this winter was similar to or lower than normal.
However, the Korea Meteorological Administration analyzed that no icing was observed as the days when the temperature was higher or lower than the normal year were uneven, and the days when the minimum temperature fell below -10 degrees did not last.
The average daily minimum temperature in Seoul has a clear upward trend, and the number of days when the daily minimum temperature falls below -10 degrees Celsius also decreases, so climate change seems to be affecting the freezing of the Han River.
The first freezing day of the Han River is also getting delayed.
The last time the Han River did not freeze with the exception of this winter was 2019, and the average winter temperature in Seoul was the warmest ever at 6.1 degrees Celsius.
