Meteorological Administration forecasts that there will be up to 300mm of heavy rain in most parts of the central area almost every day. A heavy rain warning was also given to Seoul yesterday (4th), but the rain on Jongro, the center of Seoul, was about 4 mm.

Reporter Dong-Gyun Seo will explain in detail why the forecast is missed and when the rainy season will end.

The central rainy season continues on the 43rd day.

The forecast that the Meteorological Administration said in May was about to hit the heat from late July to mid-August was completely missed.

Even so, long-term forecasts often fail to meet the weather one day later.

Meteorological Agency notice with the forecast between yesterday and today.

Over the course of two days, it predicted heavy rains over 100-300mm in many places in Seoul, Gyeonggi-do, Yeongseo and North Chungcheong, and up to 500mm in many places.

At the same time, heavy rain warnings were issued throughout the entire central region, including the metropolitan area.

The results were greatly missed.

In most regions, the precipitation was only 50 mm, and Seoul, where heavy rain warnings were issued, only showed a rain in the afternoon.

Gangnam-gu, which had the most rain, fell only 3.9mm to 47mm in Songwol-dong, Jongno-gu, the representative observatory.

The forecast was correct for the northern part of Gyeonggi Province and Gangwon, where heavy rains struck 200mm, but Incheon and southern Gyeonggi, which had reached 30mm, missed.

The forecasts are grouped together and the accuracy is poor.

In response, the Korea Meteorological Administration said, "A rain cloud can develop explosively at any time, conservatively enforcing the news."

He also explained that supercomputers based on historical data have limitations in accurately predicting abnormal climates.

This is the cloud surrounding Korea today.

As the cold air in the north and the warm air in the south stand tight, a narrow rainy season line is formed in the central region.

By this time of year, the warm air in the south should have been pushed up, but this year, the cold air in the north endures, and the central rainy season is getting longer.

This is because the high temperature caused by the high temperature in Siberia provided warm air to the North Pole, and the cold air that had to be in the north was pushed down to Korea.

The rainy season in the central part has already reached the 43rd day today, 11 days longer than the average, approaching the longest 49th.

The Korea Meteorological Administration's mid-term forecast is announced in ten-day increments, according to today's forecast, the next Saturday, so on the 15th, the rain will stop.

The predictive model used in Europe has also shown that the rain will stop in the second half of next week.

However, due to the nature of the medium-term forecast, the accuracy is not high.

Tomorrow and the day after tomorrow, the rain will expand to the whole country under the influence of the typhoon'Hagupit', which has turned into a temperate and low pressure.

This low pressure affects the rainy season front, so it is predicted that the rain will reach 100~200mm in Seoul, Gyeonggi, Gangwon Yeongseo and Chungcheong, and up to 300mm in Gyeonggi inland and Gangwon Yeongseo.
