This year's winter is forecast to cut short an unusually warm autumn weather sooner than it did in previous years as climate change plays havoc with Korea's weather.
The Korea Meteorological Administration said a high-pressure front in the North Pacific should lead to higher-than-usual temperatures in September. From 1981 to 2010, the average temperature that month was between 18 and 22 degrees Celsius.
But a continental high-pressure front is expected to develop sooner than in previous years, leading to lower-than-usual temperatures in November. The average from 1981 to 2010 was between 4 and 12 degrees Celsius.
The North Pacific high-pressure front that brought scorching temperatures this summer will continue until Sept. 10 with warm weather to last until Sept. 20 due to warm southwesterly winds.
Temperatures are then expected to return to the average of between 16 and 21 degrees, bringing typically mild autumn weather. The Arctic Ocean has melted more this year than in previous years, leading to frigid temperatures this winter. The cold Arctic air mass is expected to reach as far south as Siberia, while the region's cold and dry high-pressure front is expected to gain strength, according to weathermen.
The KMA also forecast at least one typhoon will affect Korea between September and November. "The ocean temperature around the country is between 26 to 30 degrees Celsius, which is two to four degrees higher than usual," said Kim Hyun-kyung at the KMA. "Such high ocean temperatures could aggravate the situation when typhoons form."
