"Reading the street tree and penetrating through the eyes with AI"...a leap in the forecast of a typhoon

[Anchor]
Recently, the frequency of typhoons has increased to the extent that four typhoons occurred at the same time 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.

When the news broke 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 ship is equipped with high-rise weather observation equipment such as Radio Zonde as well as water temperature and salt, allowing it to collect a wide range of marine and atmospheric information as it travels through the sea.

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 drops it into the sea to deliver important information in real time when 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 sea data from the typhoon's path and predict the typhoon's intensity and intensity.]

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

Since last year, AI and artificial intelligence technologies 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, AI has learned analysis with satellite-based data from several past 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 and greatly shortens the forecaster's analysis time.

The Met Office expands drifting observations to respond to typhoons that gradually become stronger and occur until late,
We plan to strengthen the speed and accuracy of typhoon forecasts by developing AI technology that can analyze not only the eyes of the
typhoon but also its intensity and size.
