Super Typhoon Babe (T7709/沖永良部台風 in Japan) was the only super typhoon of the 1977 Pacific typhoon season and caused a major damage in Ryūkyū Islands, Japan. The minimum sea-level pressure in Japanese land of 907.3hPa was recorded by Babe at Okinoerabu Island. Japan Meteorological Agency gave a special name to Babe: "Okinoerabu Typhoon". According to newspaper reports, Babe was "the worst typhoon to threaten Japan in 18 years". Unusually, a Hurricane Babe existed in the Atlantic basin at the same time.

Storm path

On September 1, a weak surface circulation with associated convection occurred at 7N-150E and a Tropical Cyclone Formation Alert was issued by JTWC. On September 2, Tropical Depression 10 formed near Caroline Islands at 8.3N-144.6E and was upgraded to Tropical Storm Babe at 8.9N-141.5E on the same day: a latitude of a formation of Babe was lower than that of Tropical Storm Ivan in the Atlantic Basin: he formed at 9.7N-30.3W on September 3, 2004.

At first, Babe didn't show a significant development while it moved westward: the subtropical ridge between the trough and it forced it northward. Babe was forecast to continue to move westward and make a landfall at the central Philippines. But when the subtropical ridge began to weaken on September 5, Babe changed a direction north-northwestwardly and began to strengthen rapidly. Babe became a typhoon on September 6 and was upgraded to super typhoon on September 8. Babe was the only super typhoon of the 1977 Pacific typhoon season.

Until September 8, Babe was forecast to continue to move north-northwestward and hit Taiwan. But a short wave occurred in the northern China and Babe turned to the north-northeast, so Taiwan was relieved. Instead, Japan was threatened by Babe.

Babe hit Okinoerabu Island, Japan on September 9. The minimum sea-level pressure in Japanese land of 907.3hPa was recorded by Babe at Okinoerabu Island. The previous record was 908.1hPa at Miyakojima on September 15 by Typhoon Sarah ("Miyakojima Typhoon"). An anemometer was broken by Babe's strong wind and meteorological staffs couldn't continue to measure a maximum wind.

In Japan, Babe was forecast to make a landfall at Kyūshū. But a Fujiwhara effect with the cut-off low occurred and Babe turned to the northwest. At last, Babe made a landfall as a minimal typhoon at Shanghai, China on September 10 and dissipated soon after.
