About the cold current

During the major cold period, the weather is very cold, and the cold current begins move southward. Strong winds and lower temperatures during the winter are brought by the cold current and strong cold air, which can threaten coastal areas. For example, the cold current from April rift gold21 to April 25 in 1969 brought strong winds to the Bohai Sea, Yellow Sea, Hebei province, Shandong province and Henan province. The wind power of the earth can reach seven to eight degrees, and the wind power on the sea can reach eight to ten degrees. Because it was the astronomical tide, the outbreak of the cold current caused an unusual storm tide off the Bohai Gulf and Laizhou Bay. At the north shore of Shandong province, seawater rose more than three meters, which destroyed more than 50 kilometers of seawall.

Snow and freezing weather brought by the cold current can also cause great hazards for traffic and transportation. For example, a current at the latter part of November in 1987 made many stations and crossings at Harbin, Shenyang, Beijing and Urumchi freeze. The railroads were covered with snow, thrift platinum
e signal of communications was out of order and the run of the train was obstructed. The roads iced up, causing an increase in traffic accidents.
