Weathernews announced the typhoon trend for 2023.
Due to the occurrence of the “Positive Indian Ocean Dipole Mode Phenomenon” and the “El Niño Phenomenon” of an intensity that has only been seen a few times in the past, the number of typhoons is expected to be around 29, slightly higher than normal, increasing the risk of typhoons approaching and landing mainly from the south to the east Pacific side of Japan. The risk of typhoons approaching and making landfall is expected to increase mainly on the Pacific Ocean side of Japan from south to east of the country.
During the season, the strongest “positive Indian Ocean dipole mode event” since 2019 is expected to occur. This will cause anticyclonic circulation to prevail over the eastern Indian Ocean and strengthen the monsoon blowing to the waters near the Philippines. This wind is expected to collide with trade winds east of the Philippines, resulting in slightly stronger convective activity in the vicinity of the typhoon compared to a normal year. This will result in more convective activity in the typhoon outbreak area than normal, and the number of typhoons is expected to be slightly higher than the 25.1 seen in the normal year.
At the same time, a pronounced “El Niño phenomenon” is also expected to occur. Due to this effect, the location of typhoons is expected to shift to the east or southeast of normal, and more powerful typhoons will be seen as they will spend more time passing through the sea area with high sea surface temperatures. In addition, fewer typhoons are expected to move toward the East China Sea, while typhoons tend to approach mainly from the south of Japan to the Pacific side of eastern Japan.
