[Asia Economy Reporter Lim Chun-han] During this year's monsoon and heavy rainfall periods, the accuracy of precipitation forecasts was found to be significantly low, below 80%.

On the 12th, Ahn Ho-young, a member of the National Assembly's Environment and Labor Committee from the Democratic Party of Korea, received data titled 'Recent 5-Year Meteorological Administration Forecast Accuracy Status' from the Korea Meteorological Administration (KMA). According to the data, the accuracy of precipitation occurrence forecasts in July and August 2020 was identified as 78.2% and 79.5%, respectively.

The annual average accuracy of precipitation occurrence forecasts maintained above 92% from 2015 to 2019, but as of August 2020, the accuracy dropped to 89.9%, showing a difference of about 2 percentage points.

Representative Ahn stated, “This year, abnormal climate phenomena caused by climate change have become frequent, increasing the importance of weather forecasts in reducing property damage and socioeconomic costs across various sectors such as agriculture, industry, and national infrastructure during the monsoon period.” He added, “The KMA should identify the causes of the decreased accuracy of weather forecasts in July and August, when heavy rainfall is common, and make every effort to improve the accuracy and reliability of weather forecasts.”
