Rapid Cold Wave and Heavy Snow in This Winter
It is forecast that this winter has absolute possibility of having abnormal weather like a rapid cold wave, heavy snow and so on.
The Busan Regional Metrological Office reported on December 21 that “The observation of El Nino on the surface of the equatorial Pacific ocean maintains high water temperatures until now, some 0.5~1.5 degrees higher than usual, since last July. A weak El Nino has occurred on the peninsula this winter and is presumed to maintain current weather conditions until next spring.”
Therefore, this winter is expected to have a higher average temperature than normal because the cold continental high atmospheric pressure gets weakened by global warming and El Nino effects. However, it is possible that some abnormal conditions may come, like a rapid cold wave, heavy snow, and changes of temperature.
There are some suggestions that there is a greater possibility of abnormal weather, including rapid cold waves, heavy snow and others, due to an increase in changeable width of temperatures.
In fact, winter weather shows obvious high-temperature trends fueled by global warming and urbanization. Every year, winter temperatures have been higher than average during the last 20 years, except for 1995.
In the face of global warming, urbanization and other factors, the nation has tended to have high atmospheric conditions in winter for the past twenty years. Temperatures every winter have been either the same or slightly higher than average, except 1995.
During the past thirty years, severe winter weather, including heavy snowfall or storms due to El Nino, were recorded in 1978, 1982, 1986, 1987, 1988, 1992, 1993, 1994, 1997 and 2004. Two natural disasters occurred in 1991 and 2005, and four in 1998, bringing the total to eighteen times.
The biggest disaster happened from March 4 to March 5 in 2004 when 12,920 people lost their homes and a great amount of property damage was incurred.
