Recently, the frequency of typhoons has increased so much that four typhoons occurred simultaneously in November.

Fortunately, there was no direct impact on our country, but the technology to predict the path of typhoons is becoming increasingly important.

Recently, artificial intelligence technology has enabled us to accurately capture the eyes of typhoons.

Reporter Kim Min-kyung visited the weather observation ship and the National Typhoon Center.

When the news came that the super typhoon is likely to move north to Korea, the meteorological observation ship “Weather No. 1” hurriedly completes preparations for departure.

“We’re about to leave Weather 1.”

The vessel is equipped with high-rise weather observation equipment such as Radio Zonde as well as water temperature and salinity, allowing it to collect a wide range of marine and atmospheric information as it travels through the ocean.

Since the sea cannot establish fixed observation stations like land, it collects data while moving directly and installs observation equipment in advance on the expected path when a typhoon is predicted.

It is a floating buoy that floats in the sea and collects data such as wave height and air pressure, and before the typhoon approaches, the ship goes to the prediction path and releases it into the sea to deliver important real-time information as the typhoon moves.

Beyond the drifting typhoon’s rising East China Sea, it is set up in Taiwan and the Philippines, where typhoons often develop, to prepare for observation.

(Ryu Dong-gyun / Captain 1st Weather: If you go down to the 30-31 degree line and float a drifting bouie, we can know the ocean data of the typhoon’s path and predict the intensity and intensity of the typhoon.)

The typhoon observations collected in this way are used as base data for forecasters and are also reflected in the numerical prediction model.

Since last year, AI and artificial intelligence have also been added to typhoon forecast analysis.

(Kim Dae-joon / National Typhoon Center Forecaster: Decaying and weakening typhoons are very difficult to balance. As far as I know, the AI ​​has learned analysis with satellite-based data from several previous cases, so it comes out in four minutes.

Since typhoons have the strongest winds in the snow near the center, it is important to find the exact location of the snow, and AI finds it quickly, greatly reducing the forecaster’s analysis time.

The Met Office is expanding operational watches to respond to typhoons that gradually strengthen and occur until late,
We plan to strengthen the speed and accuracy of typhoon forecasting by developing AI technology that can not only analyze the eyes of
typhoon but also its intensity and size.
