Typhoon No.15 Why is it developing? "Sea water temperature" and "compact" September 9 20:08
Typhoon No. 15, which brought a record storm to the Kanto region, developed to a very strong power in the Kanto region. Why has it developed so much? The Japan Meteorological Agency and experts analyze that the cause is “high seawater temperature” and “the typhoon was compact”.
Typhoon No. 15 has developed to a very strong power, such as the atmospheric pressure at the center of 955 hectopascals in the south of Kanto.
According to the Japan Meteorological Agency, it was the strongest class of typhoons that landed in the Kanto region in the last 30 years with statistics.
Why has it developed so much?
One of the causes is “high seawater temperature”.
The sea area in the south of Japan where the typhoon passed was about 1 to 2 degrees higher than normal, and the place where the sea temperature was high continued to the sea near Kanto.
The Japan Meteorological Agency believes that a large amount of water vapor was sent to the typhoon due to the high seawater temperature.
Furthermore, meteorological experts point out that one of the reasons is that the size of the typhoon was relatively compact.
According to Professor Kazuhisa Tsuboki of Nagoya University who is familiar with the typhoon mechanism, this typhoon No. 15 is characterized by a relatively small cloud range and clear typhoon eyes.
This compact typhoon is characterized by the fact that it is easy to develop because the clouds tend to gather toward the center, and we analyze that this was also the factor behind the development of Typhoon # 15.
