Since June 24th, 2020, South Korea's longest monsoon in seven years has been causing serious damage from heavy rains. As torrential rain fell heavily, most cities and provinces suffered massive property damage and dozens of casualties across the country including flooding of urban and agricultural areas, power outages, landslides, loss of facilities such as roads and the collapse of reservoirs. At least 31 people have died, and 11 remain missing after 54 days of rain.
Korea Meteorological Administration concluded that this unusual longer and heavier monsoon season is an extreme weather event caused by climate change. The unusually high temperatures in the Arctic region due to climate change has made upper jet stream currents have weakened which established the conditions for cold air from the North Pole to descend to the middle latitudes. This created the 'super monsoon' in East Asia this year including Japan and China.
