South Korea Improves Its Extreme Weather Forecasting Capabilities

This post was submitted by Climate Scorecard South Korea Country Manager Jitae Chang

South Korea is no exception to global trends toward extreme weather events. The country is losing its spring and autumn seasons, which has serious consequences for their agriculture and fishing industries. In some places, the agricultural industry has had no choice but to replace several traditional crops with Southern Asian tropical species that are not native to the area.

According to the National Institute of Meteorological Science (NIMS), compared to the early twentieth century, the recent thirty-year average annual temperature has increased by 1.4˚C in South Korea. This has resulted in unpredictable weather conditions, such as sudden localized heavy rain and sudden coldness.

NIMS reports that climate change cost South Korea 162 lives and 5.4 billion USD of property over ten years (2007–2016). It recommends that South Korea work with the Intergovernmental Panel on Climate Change (IPCC) more closely than ever to provide meteorological data and collect more correct climate change simulation data.

Since 2008, the South Korean government has deployed aggressive climate change actions, such as promoting a number of green energy and renewable energy projects. The Korea Meteorological Administration (KMA) has developed an extreme weather warning system, with indicators benchmarked from other advanced countries.

KMA saw the need to publish dedicated meteorological technology and policy journals in order to develop a more accurate weather prediction system and exchange information with the public. They started publishing two journals: Meteorological Technology and Policy and Meteorological Technology—Policy Information Trend. The first focuses more on what we should do to improve our preparation and response to extreme weather changes, and the kinds of available technology. The second journal looks at what other countries are doing to improve the prevention of extreme weather changes. As of this month, these two periodicals have reached the 32nd issue and 497th issue, respectively.

With the knowledge and technologies now available, KMA can more accurately and quickly analyze unexpected local weather conditions. Their extreme weather forecasting and warning ability has greatly improved since 2008; it is still impossible to anticipate the weather with 100% accuracy. South Korea tragically suffers casualties every year because of extreme weather changes. While the total number is decreasing, and as KMA continues to improve, more lives and property will be saved.

Current ability of the country to adapt to extreme weather conditions it faced in 2021:
