It is news that there is no sign of the rain to stop, but rather it will be expanded to the whole country. I will talk more about this rainy season with reporter Seo Dong-gyun, who is in the studio.

Q. When is the rainy season ending?

[Reporter Dong-Gyun Seo: The Korea Meteorological Administration is forecasting the medium-term forecast for the next 10 days, but in the meantime, when I checked the medium-term forecast, the rain was forecast more each day. So, the rainy season has been extended, but according to the forecast released today (5th), it was predicted that the rain will stop on August 15th, next Saturday.

We have also confirmed the results of using the numerical forecasting model used by the European Mid-term Forecast Agency, but the forecast is expected to stop when the Wednesday passes over the end of next week. As the forecast gets longer as the date gets longer, the accuracy decreases, so I have to keep in mind the possibility of medium-term forecasting and refer to it.]

Q. Seoul, which almost rained yesterday… Should I see the forecast as wrong?

[Reporter Dong-Gyun Seo: The Korea Meteorological Administration forecasted a lot of rain yesterday and yesterday at dawn in the metropolitan area including Seoul and the central region. Up to today, 100~300mm, and in many places where there is a lot of rain, forecasted a rain of up to 500mm or more, while heavy rain warnings were lowered all day in the central region almost yesterday. This heavy rain warning is a heavy rain that takes effect more than 90 mm in 3 hours and 180 mm in 12 hours, but yesterday Seoul rarely rained, as we felt, and the most heavily rained area was Gangnam. Yesterday 49 mm fell.

In Cheorwon, Gangwon-do, as it was predicted, it rained a lot more than 250mm, and most of the rain except for Gangwon-do and some northern parts of Gyeonggi Province was a little different from the forecast. However, it is recommended to prepare thoroughly because the river overflows due to the large amount of accumulated rain and the water level of the Han River is rising, causing heavy rain damage even in areas where there is no direct rainfall.]

Q. Up to today, the best from 500mm to 7 days The forecast has changed to 400mm, right?

[Reporter Dong-Gyun Seo: Because I made a forecast yesterday, I said that 500mm will come to this day, but it rained a little less yesterday. Today, we will have to do some more observations, but once we see yesterday, the forecast from the Korea Meteorological Administration may be a little out of place.]

Q. What would be the characteristics of this rainy season?

[Reporter Seo Dong-gyun: Once the North Pacific high pressure pushes the warm rainy season in the south and the force of cold air in the north boils, the rainy season couldn't be raised further and it is stagnating now in the middle. Because of the similar power, the width of the rainy season was also very narrow. In the same case yesterday, the width of the rainy season was about 15km north to south. Because of this, there is a great deal of difference in precipitation between the North and the South, but there is a lot of rain and rain, even if it goes up a bit, rain falls even if it goes down a little to the south.

Another feature is that the rain is concentrated at dawn time, which is difficult for people to prepare for. This phenomenon occurs because the water vapor tends to turn into raindrops at night, and the wind over 1.5km that flows into the water during the day The wind weakens due to the turbulence caused by the heating of the surface, but when the turbulence disappears at night, the wind that can supply more water becomes stronger, so the supply of water vapor increases and the rain is concentrated mainly in the early morning hours.]

Q. This rainy season is longer Is there any particular reason to lose?

[Reporter Seo Dong-gyun: As I said earlier, the North Pacific high pressure forming the rainy season front, the warm North Pacific high pressure in the south and the cold air in the north have similar powers. Originally, in the summer, the word that heat is coming is when the warm northern Pacific high pressure pushes the rainy season front as it expands its power, and the heat is coming and the rainy season ends. In this year, the high temperature of Siberia caused the cold air to come down from the north. As this cold air adds strength, the high pressure of the North Pacific in the south is not lifting the rainy season front.

In this way, the rainy season is continuing on the 43rd day, and the 32nd day of the week has already passed. This is because the power is not being used on either side. The 49th of 2013 was the longest rainy season. According to the forecast of the Meteorological Administration, it is expected that it will be at least 49 days in the future, so this year is expected to be the longest rainy season.]
