The Han River has frozen. This is a week earlier than the average. It has frozen 37 days earlier than last winter.
The Korea Meteorological Administration announced on the 3rd that the Han River has frozen due to the ongoing cold wave at the end of the year and the beginning of the year.
It is said that the Han River froze when a virtual rectangular area set at a 100m upstream section between the second and fourth piers of the Han River Bridge connecting Dongjak-gu and Yongsan-gu was completely covered with ice, making the river water invisible.
Observations of the Han River freezing in our country began in 1906. Over the past 100 years, the terrain and scenery have changed, but the observation point remains the same.
The Han River freezes when the minimum temperature in Seoul stays below minus 10 degrees Celsius for more than five days, and the daily maximum temperature also remains below zero.
After the minimum temperature dropped below zero on the 29th of last month and did not recover to positive, the Han River also froze.
The Han River froze the earliest on December 4, 1934, in observation history. The latest was on February 13, 1964. Additionally, freezing was not observed on nine occasions, including in 1960, 1971, 1972, 1978, 1988, 1991, 2006, 2019, and 2021.
Meanwhile, the Han River has been freezing later compared to the past. This is attributed to the deepening and straightening of the river due to the Han River Comprehensive Development Project in the 1980s, which increased the flow rate, and the rise in temperature due to climate change.
