Full launch in 2022! Japan prepares "artificial typhoon"

According to the "Japan Keizai Shimbun" website reported on the 18th, in response to the strengthening trend of typhoons brought about by global warming, the "artificial impact typhoon" project jointly participated in by Japanese government agencies, universities and enterprises will be fully launched in 2022.

According to the report, statistics from Japan's Ministry of Land, Infrastructure, Transport and Tourism show that in recent years, disasters such as heavy rain caused by large typhoons making landfall in Japan have continued to increase. The team of Professor Hiroshi Koho of Yokohama National University calculated the effect of artificially influencing typhoons through simulation experiments. "The eye of the typhoon is warmer than the surroundings, and the water vapor from the updraft from the ocean provides sustained winds. If the atmosphere in the typhoon's eye is cooled, the updraft may weaken, which in turn weakens the typhoon's wind. Using Typhoon No. 15 of 2019 as a model, he envisioned spraying a large amount of ice into the eye of the typhoon within 30-50 kilometers, and the calculations showed that the maximum wind speed was reduced by 3 meters per second, which could reduce the damage to the building by 30%.

However, the report also mentioned that if you want to affect the typhoon through artificial rain and other methods, the rain that should be received elsewhere will be reduced. If the scale of artificial rainfall is huge, it will no longer be a problem for a single country, and a legal framework such as international coordination and attribution of responsibility for problems will need to be established.
